I've found that you will have much better luck with a smaller company. The smaller company needs your "small" purchases. HP couldn't care less. You don't affect their bottom line.

Or, alternatively, calculate the cost of paying twice as much for the equipment simply for the promise of support. If I'm following the numbers correctly - 20K for 10 TB from HP - you could buy 2 12 TB units from abernas for about 17K. Cheaper, and you now have a ready, live, hot backup. If they both fail in 5 years? And the company is out of business? Take that 3K that you saved, and use it to buy a new 100 TB system.

There is no 4 partitions limit - a PC hard drive can have up to 15 partitions. There is a limit of 4 _primary_ partitions, but one of those can be an 'extended' partition, containing 11 (or 12) _logical_ partitions. Windows insists being installed in a primary partition, Linux does not care. Boot from the slack CD and switch it to 'rescue' or 'maintenance' mode instead of the 'install' mode. Then run the following command dd if=/dev/zero of=/dev/hda bs=1M count=1 [If it complains about hda being read-only, substitute sda for hda and try again]. This will clear out the partition table. Next, install Windows and during installation create the first partition, which will contain Windows. After that, boot with the slackware disk. When you create the first two partitions (swap and /) use primary disks. Then, create the others as logical disks. [c]fdisk will implicitly create the extended partition and place all the logical disks in there. Then, proceed with the installation.

I dual boot slack & windows, and have done this setup many times without fail. The easiest way to do this is with a 3rd party bootloader (I like boot magic), but you can do it with the resourses you have as well. Install windows as normal, or repair your windows MBR if you destroyed it on accident. Then install slack, but do not put lilo in the MBR. Put lilo on the slackware root partition - "root partition's superblock" I believe they call it in the install (also do not pick simple install for the lilo, make a custom lilo, and point to your proper slack / or /boot partition ie:/dev/hda5). Very Important - Make sure to create a Slackware boot disk. Once Slack is installed, reboot into Slack using the boot floppy. Log in, and su to root. Check your /etc/lilo.conf file to make sure it is accurate. Should look something like: # Start LILO global section boot = /dev/hda5 #(make sure this is your slack root partition) message = /boot/boot_message.txt prompt timeout = 100 # Override dangerous defaults that rewrite the partition table: change-rules reset # VESA framebuffer console @ 1024x768x256 vga = 773 # End LILO global section # Linux bootable partition config begins image = /boot/vmlinuz root = /dev/hda5 #(make sure this is your slack root partition) label = Slackware read-only # Linux bootable partition config ends ** if you make any changes at this point, remember to run "lilo" after your done editing to install your new lilo. Now, grab a DOS formatted empty floppy (sorry should have mentioned you'll need one earlier), and mount it. You should not need to mount the floopy since you just booted from a floppy, but if it need to be mounted try: (as root) mount -t msdos /dev/fd0 /mnt/floppy The following command will copy your lilo onto the floopy: dd if=/dev/hda5 bs=512 count=1 of=/mnt/floppy/linux.bin Pop out the floopy, and reboot into windows 2K. Once booted copy the contents of the floppy to the root of the windows drive, most likely C:\ Now edit the windows boot.ini file (I like vim for windows, but you can use notepad). Add the following to to the bottom of boot ini. c:linux.bin=?Slackware" Reboot without any floppies in the drive and viola you should be able to choose which OS you want to boot into! If you have gone and turned off the display of other operating systems, you will need to turn that back on. If you don?t know how or don't remember, right click on ?My Computer?, click on ?Properties?. This brings up the ?System Properties? window, click on the ?Advanced? tab and then the ?Startup and Recovery? button at the bottom. You should see the first check box unchecked, simply put a check in the box and then set the number of seconds the display is up before booting into the default OS! I have done trick over 100 times without a problem. I hope you think pad has a floppy, if not... well good luck. Good Luck!!!

Yes, I did restart the x-server. In fact, I restarted the computer. Also, something else I tried - I noticed the xorg.conf had modelines, so after some digging I used the gtf command line utility to generate a new modeline and pasted that into xorg.conf and restarted. The screen res utility now shows the correct 75Hz, but the flicker problem remains. Actually flicker might not be the best word. On moving images like a screen saver, the image is sometimes flashed onto the wrong part of the screen, so you get a kind of jagged lightning-like ghost-image effect. It's not fun. This is the only version of Linux I've had this problem - I have this monitor hooked up to an older machine with Debian Etch and that drives the monitor just fine.

You can cut and paste sections into xorg.conf if you've got a copy of your old one, but for crying out loud, what kind of solution is that? I've got the same problem, Ubuntu thinks my monitor only goes to 1024x800. Manually adding the modeline works, but it will not start X at 1200x1024 no matter how I try to convince it. Even cut and pasting the entire section into xorg, with 1024x800 commented out, doesn't stop it from starting X at 1024x800.

I've been using Kubuntu v7.10 and noticed that my xorg settings kept changing back every time I had to reboot (initial install glitches). So I made a backup of the file the way I wanted it and rebooted. Lo and behold, some 'automagical' process has nuked my settings and restored the ones that didn't function very well. My solution. Make the changes to the xorg file so you get the resolutions you want, make a backup copy, then change the permissions to 444. Problem solved. What ever 'automagical' process was messing with my settings is no longer allowed to change them. -- ========== Todd Young -------------- Original message ---------------------- From: Pete > On Mon, May 5, 2008 at 12:12 PM, Thomas Johnson wrote: > > > I believe that xorg.conf is still the place to override the 'handy' > > auto-configuration nonsense.

Jeremy ---------- Forwarded Message ---------- Subject: A special minnebar reminder Date: Monday 05 May 2008 From: Ben Edwards To: MinneBar MinneBar is this Saturday, May 10 at Coffman Union at the U of M. Now with 50% less sweltering heat and sweaty geeks! 300 people have already signed up to attend and there are over 40 diverse sessions focused on development, design, and business-related topics. If you haven't signed up yet, please add your name to the wiki page now. Edit http://barcamp.org/MinneBar (the "invite code" is "c4mp") and add your name. Full details and the session list are available on the wiki. * Pre-event Mixer * It's back - a chance to get to know some of the participants before participating. Come down to the Bulldog NE this Friday night for some free appetizers and conversation. The fun starts early, at 6pm. This mini-event is being sponsored by Refactr LLC. Here's a link to a map: http://tinyurl.com/4fyjgp * Still room for sessions and demos * We have a lot of space for more sessions so if you got something you want to share with others, add it to the sessions page: http://barcamp.org/MinneBarSessions Another great thing about having a lot of extra rooms will be the opportunity for "ad hoc" sessions to spring up. Perhaps a session will spark another topic or you find yourself excitedly talking to a colleague about a great idea, sign up on the "ad hoc" session board and grab a room. We'll do our best to send out a tweet on the topic/ location as well. * Blog/Twitter/Email -- Spread the word * Please help us spread the word about MinneBar with your co-workers, friends, ex-lovers, whoever. Blog posts, Twitter mentions, and email forwards really help us out. (Speaking of Twitter, make sure you follow @minnebar to get updates during the event.) Can't fill up an hour, but still have something cool to show off? Give a five minute "lightning talk"! Send an email to look at recursion.org to sign up. * Sponsor loving * Last but not least, we'd like to thank our sponsors again for making this event possible: * University of Minnesota Software Engineering Center (Venue Sponsor) - http://www.umsec.umn.edu * Split Rock Partners - http://www.splitrock.com * ipHouse - http://iphouse.com * Swarmcast - http://www.swarmcast.com * Sierra Bravo - http://www.sierra-bravo.com * FindLaw - http://www.findlaw.com Be sure to thank them at the event.

Then pick two 8^) If you want real RAID, you need to go to 3WARE, Areca, Hightpoint, Adaptec or LSI Logic, and cough up $100 or more per port. But you get hardware raid, battery backup for the cache, better management, maybe some extra checksumming. If you want decent host-based RAID you can try the Addonics stuff. They have a nice line of external SATA enclosures and multi-port cards. They have 4-port RAID for around $100, either internal or external. If you want cheap, go with a JBOD controller and use the Linux software RAID implementation.

I'm not even sure you can find more than two port pci controllers, let alone with RAID capability. In PCI-X or PCI-e you can definitely get in the game for less than $100/port, ala the 3ware 9550/9650. If I recall my Highpoint 2300 was under $200 for 4 ports some time ago, but it has no battery capability. It does have real management and all the features of a real controller, including in-OS OCR/OLRM. PCI-e though. If you're stuck with 32 bit PCI slots I'd get a plain SATA controller and use linux's software RAID. Performance is going to be limited by the bus anyways. -- Thanks, Josh Paetzel PGP: 8A48 EF36 5E9F 4EDA 5A8C 11B4 26F9 01F1 27AF AECB -------------- next part -------------- A non-text attachment was scrubbed...

Use 'badblocks' for surface testing and 'smartmontools' for the rest of the circuitry. For badblocks, I'm using the following incantation: badblocks -s -v -c 128 -b 4096 -w Depending on the speed and capacity of the drives, it could take a whole day. With smartmontools, you use the 'smartctl' program to look at the values of the SMART counters, which include certain classes of errors. You use: smartctl -a /dev/[hs]d[abcd] depending of the type and physical position of your drive in the system. If the 'SMART Error Log' section contains the 'No Errors Logged', then you are half-way out of the woods. To make sure, start a exhaustive self-test with: smartctl -t long /dev/[hs]d[abcd] The program should tell you how long the test will take and when to come back and run the 'smartctl -a' to get the results. BTW: you should run 'badblocks' before 'smartctl', to give the whole disk surface a good scrub. The error counters reflect only errors that occurred while attempting to operate on a sector. If the sector is corrupted but nobody asks for it... it won't be counted. Good luck, florin -- Bruce Schneier expects the Spanish Inquisition. http://geekz.co.uk/schneierfacts/fact/163 -------------- next part -------------- A non-text attachment was scrubbed...

I should have tried that first. To answer some of the questions that people had; yes Slackware still relies on LILO ,but does not prevent using GRUB - the reason being a desire to stick to the method with the longest track record - the tried and true. The reason that I did not try copying the first 512 bytes of the Linux partition to the Windows NT partition and modifying boot.ini is that method is described in the Slackware book as a deprecated NT hack that should not be needed, as the current version of LILO has no problem with Win 95,98,2K... (That 'hack' worked quite nicely after I updated the BIOS to the latest version - 1.22 (2001/10/12) ) That fdisk is limited to 4 primary partitions was only a problem due to my ignorant assumption that Linux needed to live on primary partitions. All of my problems were due to my antique BIOS not being willing to look at anything beyond the 1023rd cylinder.

I started with 7.10 and have upgraded to 8.04. Under 7.10, hibernate worked most of the time and suspend didn't work at all. Under 8.04, suspend seems to work perfectly and so I haven't tried hibernate. (No guarantees on that for future kernel & driver updates, but I've yet to have it not wake up since the dist-upgrade.) I imagine that the latest Fedora et al would work just as well, but have no personal experience. This is a nearly new Dell Vostro 1400 which listed at $1,497.00 and has the following specifications: Vostro 1400 Intel?

Also, I paid more for the higher resolution screen, so you can see a lot in the 14" of space. Do you work with photos? You'll love the screen. The warranty travels with the machine. You'll get full coverage and years of on-site service directly from Dell, so you don't have to worry about buying a used machine. I did get it on sale a few months back, but I paid hundreds more than I'm now offering it at. Why? Because I know that computers get cheaper over time. (*grin*) Just now, I went to Dell's site and tried to configure the same thing. Their options have changed slightly, but the closest thing that I could come up with had a price tag of $1223.64 (inc. tax -- Dell, despite being mail order, does charge sales tax in MN). 80% of that price is 978.91, so I think that $975 is a very fair price for this great system. This sleek, black notebook computer has very rarely left my home office and, when it has, it was carried around in a really nice padded case. Q. So, why am I selling it? A. Because my work will be buying me a newer laptop with a much larger screen for presentations and there's no sense in this sitting around unused. I plan on restoring it, using the factory-supplied discs, to the exact original software configuration. If you want me to put XP (ugh) instead of Vista (double Ugh) on it, I'm willing to do so, but it'll be $50 more for the hassle and for using up one of my old OEM XP licenses. If you want Ubuntu Linux (which is what I've been using), I'll do that for free. LOCAL BUYERS ONLY. I will NOT, repeat NOT, ship this to you, so don't bother trying to scam me. Questions? Please ask.

Even though it's not what you want I would look at some of the job listing sites. At least that way you'll get some clue of the basic skills required such as shell scripting, log analysis, etc. Also, every site handles things a little differently so I don't see how you can really do this without the input of your Linux/UNIX team.

Robert, If it wasn't for your first sentence, I'd have no trouble recommending Request Tracker (http://bestpractical.com/rt/). I've used it for several years with great success. It requires a certain investment to install and configure, but once it's rolling I think you'd find it to be flexible and powerful. -Tim -- Tim Wilson, The Savvy Technologist Twin Cities, Minnesota, USA Educational technology guy, Linux and OS X fan, Grad. student, Daddy mailto: wilson at visi.com aim: tis270 blog and podcast: http://technosavvy.org From erikerik at gmail.com Thu May 15 12:35:22 2008 From: erikerik at gmail.com (Erik Anderson) Date: Thu, 15 May 2008 12:35:22 -0500 Subject: [tclug-list] Trouble Ticket type systems In-Reply-To: References: Message-ID: I set up Request Tracker at work about 5 years ago, and it's worked flawlessly ever since. It easily satisfies your requirements. We currently have about 6 queues configured in RT, and are creeping up rather quickly on 20k tickets. RT is somewhat of a pain to get installed, as it has a ton of perl module dependencies. Fortunately, they include an installer script that takes care of 95% of that for you, so it's not a big deal. We currently have RT set up so that for ticket submission, users just send email to a certain email address. Every 10 seconds or so, RT checks that box and pulls down any new messages. Upon ticket submission, the users get an autoreply back - this message includes a web link they can use to view their ticket directly. It would be easy enough to set permissions such that any user can view the whole queue, though, like you wanted to do. -Erik On Thu, May 15, 2008 at 12:21 PM, wrote: > Hello, and a good day to all.

I've used dotProject [1] in the past in a few different situations and found it quite useful. In the end, I customized all of them and found it to be pretty simple as well. The helpdesk plug-in should do what you want off the bat and since it's been a while since I last used it, it might be incorporated by now.

The difference is in the procmail recipe: if the destination ends with a / then it's treated as a maildir. If you have separate recipes for users, it is trivial to modify yours however you want, without impacting anybody else. > Also will I need to run a separate IMAP server for myself to be able to > access these mailboxes, while others still use mbox? Dovecot seems to be able to convert on the fly: http://wiki.dovecot.org/Migration/MailFormat > And is there a way to convert my mbox mail to maildir format? Yes there are several, but you need to test them. Last time I used a program called 'formail', that comes with 'procmail' and I had some errors - but I was converting some mailman archives which looked like honest mboxes, so I don't know if the bug was in the mailman or in the recipe.

I am about to order a new server for my job, and I was wondering about the raid controller option. The box is going to used for running a very busy database. I have the option for Intel SAS RAID Controller or Intel SAS RAID Controller w/ Portable Cache Module (Add $450.00) I am planning on running 2 drives as raid 1 for the OS (Slackware), and 3 drives as raid 5 for the database. What is the benefit of the Portable cache module. I am not concerned about the price, just if this is something I should consider. Any thought would be great. Thank You!!!

That way if the server loses power while data is waiting to be written to disk, you won't lose data. This is especially important for databases. It is also important to enable write-back cache if you have battery backed cache. If you don't have battery backed cache then you really should do write-through to prevent data lose. The difference between write-back and write-through is write-back stores the data to be written in cache and tells the operating system it can continue. Write-through makes the OS wait, which is slower. Some controllers allow you to adjust what percentage of cache is used for reads and writes. If the controller has 256MB of cache, I'd just give 50% to each and see how things perform. It depends on how your database is being used, but if you have 256MB of cache and are read heavy, I'd consider testing 75% read, 25% write. One last recommendation, you may want to consider getting 6 or 8 drives and doing RAID 1+0. The performance is much better for reads and writes than a RAID 1 and a RAID 5, plus you're still redundant.

For the most part this is true, however on a lot of modern RAID controllers if you hook 12 drives up in RAID-5 you are going to see amazing performance. Here is an article with a very thorough review of 9 SATA RAID cards: http://tweakers.net/reviews/557/26/comparison-of-nine-serial-ata-raid-5-adapters-pagina-25.html The issue here is that they do not do a RAID-10 test with 12 drives. I don't know what they are doing on the Coraid SR 1521 to make RAID-5 faster than RAID-10, but when you get up to 14 drives in the chassis you get much better throughput, now mind you this is not random I/O, just another thing to think about: http://coraid.com/support/sr/ANSR002.pdf For a large number of drives in a RAID-5 you get really good performance and much higher capacity. Not that this is really relevant to the original poster.

The benchmarking was random reads and random writes of varying sizes (multi-gig to make sure it was beyond the total cache available). RAID0 = fastest (just for fun and to set the watermark) RAID10 = second fastest (about 65% of RAID0) RAID5 = a very very distant last (about 20% of RAID0) These % numbers are rough and from memory of several weeks ago.

It's never a bad time to learn something new. There's usually multiple ways to do something. One thing to note is that with -delete if a delete fails find will exit non-zero (after find finishes). This is something to consider when calling find in a script and using -delete. Also -depth is implied with -delete so when including directories in the find search that is another thing to consider. This case is simpler as its only files. -----Original Message----- From: tclug-list-bounces at mn-linux.org [mailto:tclug-list-bounces at mn-linux.org] On Behalf Of Bret Baptist Sent: Thursday, May 29, 2008 11:52 AM To: tclug-list at mn-linux.org Subject: Re: [tclug-list] sftp/scp server with ldap/AD integrated authentication On Thursday 29 May 2008 11:41:44 am Justin Krejci wrote: > cron+find is your friend here.

Samba+Winbind can do the AD integration. Smaba3 can participate in AD as a full domain member computer and authenticate AD users for accessing your Linux computer. Once Samba is configured and joined to AD, you have to edit your PAM configs to use the winbind module and update nssswitch.conf. Everything you need is in the samba manual. If you wanted to go a step further with the AD integration you can fully kerberize your Linux box by installing the kerberos aware versions off sshd and other services. You will have to learn how to set Service Principle Names in Active Directory (using setspn.exe command line utility or ADSI Edit MMC) and just learn a bit how Kerberos works in general. The easy part is that MS Active Directory is also a Kerberos Domain and Samba in AD member mode has already done the Kerberos client setup for you, even creating the SPN needed in AD for Kerberos single sign on connections to your Linux samba server from a Windows (or other domain member) computer. If you are going to open up SSH to the internet you may want to consider setting up firewall rules to filter out unwanted IP addresses. I have a SCP/SFTP server setup to meet the needs of a customer and it was getting constant SSH requests. I ended up restricting it to only accepting SSH connections from the customer's IP range and local network to get rid of the bots that were searching for exploitable SSH installations or just trying to brute force things. If you have an Account Lockout policy set on your AD domain (and if you don't, why not?) a public SSH server could easily lock out numerous AD accounts. Don't bother trying cifs or smb over the Internet. It will work, but it is so slow it may as well not work at all. If you really need to do cifs/smb over the Internet, use VPN. It will still be slow but there will at least be some security there. -- Andrew S.

OK, My new server is going to have 6 drives. I am going to go with RAID10. For the first part (raid 1), do I want to make two or three sets. For Example, do I want to make drive 1+2, 3+4, 5+6 RAID 1, or can I do 1+2+3 & 4+5+6 as RAID 1. What do you think is best. Then for the second part (raid 0), I guess that depends on how the raid 1 was setup. Your thoughts are greatly appreciated!

I'd do whatever makes it easiest to service from the front of the system. It's a pain if you've got one array that jumps around *physically* on the front of the box. In other words, if the drive setup is two rows of three drives, I'd do one stripe on all three drives across the top and the second stripe across all three drives along the bottom. Odds are, this is going to be 1,3,5 and 2,4,6 as your stripes. If, however, you've got a box where all the drives stand on their edge in one single row, I'd recommend 1,2,3 as one stripe and 4,5,6 as the second. Does this answer your question? ----- Eric F Crist Secure Computing Networks From goeko at Goecke-Dolan.com Fri May 30 10:25:55 2008 From: goeko at Goecke-Dolan.com (Brian Dolan-Goecke) Date: Fri, 30 May 2008 10:25:55 -0500 Subject: [tclug-list] *Tomorrow* OLPC (One Laptop Per Child) - Topic @PenguinsUnbound Linux Meeting May 31st, 2008 Message-ID: <48401C83.6070202@Goecke-Dolan.com> This months PenguinsUnbound.net meeting will be Saturday May 31st, 2008 at TIES, 1667 Snelling Ave. N., St. Paul, MN 55108 from 10:00am to 12:00pm (See the web site http://www.penguinsunbound.com/Location_for_Meetings for directions and more info.)

It's a horrific choice for a database that is going to see any sort of write load. Not only do you have to calculate parity, but you have to seek every head in the array to do a write. In practice on a heavily loaded database server seek times on the drives dictate throughput. I have database servers with RAID 10 arrays of 15k U320 drives that never manage to do 20Megs/sec of throughtput, even though they are completely I/O bound. While a sequential read or write can be nearly 15 times that. -- Thanks, Josh Paetzel PGP: 8A48 EF36 5E9F 4EDA 5A8C 11B4 26F9 01F1 27AF AECB -------------- next part -------------- A non-text attachment was scrubbed...

This may not be exactly what you are looking for, but I would take a look at Linux-based NAS. I recently got a Buffalo LinkStation that can do everything on your list, but depending on your requirements a TeraStation might make more sense for you - http://www.buffalotech.com/products/network-storage/. If you want to consider Buffalo, take a look at http://buffalo.nas-central.org/index.php/ . There are two main options for opening up the software on the NAS. You can keep the stock firmware and add softare on top of it, or you can move to new firmware and run a different Linux distribution on it - I run Debian. Anyway, I know that there are other similar products out there - the Linksys NSLU2 is a popular one - but a NAS might do what you want. Or depending on your needs, you culd problably just use samba, ssh, and cron to set it on an old box that you have lying around. -- Jim Crumley |Twin Cities Linux Users Group Mailing List (TCLUG) Ruthless Debian Zealot |http://www.mn-linux.org/ Never laugh at live dragons | From stuff at cb1inc.com Fri May 30 14:11:05 2008 From: stuff at cb1inc.com (Chris Barber) Date: Fri, 30 May 2008 14:11:05 -0500 Subject: [tclug-list] OT - Hardware Advice In-Reply-To: References: <05aa01c8c0dd$f56b8970$eb17a8c0@usicorp.usinternet.com> <200805281347.40614.josh@tcbug.org> <200805281511.30877.bbaptist@iexposure.com> <483DC74A.2040006@cb1inc.com> <483ED2F9.7040607@cb1inc.com> Message-ID: <48405149.9010004@cb1inc.com> What you would do is create a new logical array that included all 6 disks. Then it asks what RAID level you want. Almost every RAID controller I've seen allows you to pick a valid RAID level for the number of drives you selected. In the case of 6 drives, you commonly should be able to do RAID 0, 1, 1+0, 5, 6. If you don't see RAID 1+0 in the list, make sure your controller can even do RAID 1+0. Once you have a single large logical drive, go ahead and install the OS on it and as I recommended in my previous email, allocate 2-4GB to swap area and the rest to your OS and data files. Some people like creating a separate partition for data, and that's cool, but I've run into issues with running out of disk space one of the partitions. When you run out of space, pretty much your only choice is to format and re-install. I suppose you could add more drives and expand the array, then figure out how to grow the file system, but expanding a RAID array takes forever and a day. And after you've reinstalled your OS a couple times, fancy partitioning schemes can be annoying to setup again. -Chris Robert De Mars wrote: > Chris Barber writes: > > >> Nope, use all 6 disks in the RAID 1+0.

Hoping there is someone else on this list that has a solution. I am trying to transcode an avi file to a wmv file that wmp can play. I'm using Ubuntu 1.7.10. , and installed vlc via apt. When I attempt to transcode the avi file I get the following error: ffmpeg error: cannot find encoder MPEG Audio layer 1/2/3 stream_out_transcode error: cannot find encoder ((null)) main debug: removing module "mpeg_audio" stream_out_transcode error: cannot create audio chain main error: cannot create packetizer output (mpga) So, I get video, but no audio. I transcoded the same file on a vista box, and it worked perfectly. From all the googling around it seems Ubuntu's version of vlc may not have mp3 encoding capabilities built into it because of licensing issues. I rebuilt ffmpeg to include lamemp3, and was able to convert the avi to wmv via the command line, but could not get it to work via vlc, so I uninstalled vlc and reinstalled via src, thinking I configured it correctly, but in the end, it performed worse than the standard install. Hoping someone knows the proper ./configure options so I can get this to work, or is aware of another way to fix the problem. -- Raymond Norton LCTN -------------- next part -------------- An HTML attachment was scrubbed...

Syslog is one example. Also if you get a dirty partition that needs a fsck then the larger it is the longer time for recovery. _____ From: tclug-list-bounces at mn-linux.org [mailto:tclug-list-bounces at mn-linux.org] On Behalf Of Chris Barber Sent: Friday, May 30, 2008 2:11 PM To: Robert De Mars; tclug-list at mn-linux.org Subject: Re: [tclug-list] OT - Hardware Advice What you would do is create a new logical array that included all 6 disks. Then it asks what RAID level you want. Almost every RAID controller I've seen allows you to pick a valid RAID level for the number of drives you selected. In the case of 6 drives, you commonly should be able to do RAID 0, 1, 1+0, 5, 6. If you don't see RAID 1+0 in the list, make sure your controller can even do RAID 1+0. Once you have a single large logical drive, go ahead and install the OS on it and as I recommended in my previous email, allocate 2-4GB to swap area and the rest to your OS and data files. Some people like creating a separate partition for data, and that's cool, but I've run into issues with running out of disk space one of the partitions. When you run out of space, pretty much your only choice is to format and re-install. I suppose you could add more drives and expand the array, then figure out how to grow the file system, but expanding a RAID array takes forever and a day. And after you've reinstalled your OS a couple times, fancy partitioning schemes can be annoying to setup again. -Chris Robert De Mars wrote: Chris Barber writes: Nope, use all 6 disks in the RAID 1+0. That way you get more throughput. I like things easy, so I would just create a root partition that eats up almost all of the space, then a second small (2GB) swap area. That way you don't have to worry about running out of disk space if you make a particular partition too small. -Chris Forgive me for asking so many questions, but I am still a virgin to RAID, and this is going to be my first RAID setup. OK, My new server is going to have 6 drives. I am going to go with RAID10. For the first part (raid 1), do I want to make two or three sets. For Example, do I want to make drive 1+2, 3+4, 5+6 RAID 1, or can I do 1+2+3 & 4+5+6 as RAID 1. What do you think is best. Then for the second part (raid 0), I guess that depends on how the raid 1 was setup. Your thoughts are greatly appreciated!

I was originally planning on running the OS, and database separate from each other. How should I proceed with the install. Would it be best to run the OS as RAID 1 (2 disks) as originally planned, and run the database on RAID 1+0 (4 disks)? Or, should I run the whole thing (OS & Database) on one huge RAID 1+0?

It's what's inside the container, which may cause you a problem. So, the real question is - what codec do you try to use to encode your video and audio. Obviously you try to use mp3 as audio codec, which is not included with the Ubuntu's vlc. Then try mencoder or transcode to do the job, or try with other codec - can't you use wma? What is the original audio codec used in the avi? If it is mp3, try using copy of the audio stream (not transcoding) and transcode only the video. -- Svetoslav Milenov (Sunny) Even the most advanced equipment in the hands of the ignorant is just a pile of scrap.
