Thanks to everyone for the help regarding the LVM on RAID question I
had the other day. There's another issue with it that I'm trying to
resolve, and that is getting the RAID5 to initialize on startup.
Problem history review:
Originally, it was a RAID0 (not my design) and converted to RAID5
(yay!) after the owners suffered a disk failure. On bootup, all other
RAID devices initialize. However, this RAID5 doesn't.
>From my understanding, this line in the /etc/raidtab is required for
it to be read and initialized on bootup:
persistent-superblock 1
Again, here's the /etc/raidtab relevant info:
raiddev /dev/md4
raid-level 5
nr-raid-disks 3
chunk-size 64k
persistent-superblock 1
parity-algorithm left-symmetric
nr-spare-disks 0
device /dev/sdc1
raid-disk 0
device /dev/sdd1
raid-disk 1
device /dev/sde1
raid-disk 2
After bootup, I can initialize the /dev/md4 device and then mount
filesystems by hand and it works. If I wanted to, I could throw it
into the rc.local script, but that's a hack and not the way I want to
do it.
I do have a call into RH for support on this, however, they're being
extremely slow to respond... I've googled this, but so far am not
finding much that's helpful.
Further thoughts?
