what's up with my mdadm? note how it's taking 97% of CPU: >top - 11:40:14 up 1:16, 1 user, load average: 1.02, 1.04, 0.90 >Tasks: 187 total, 2 running, 185 sleeping, 0 stopped, 0 zombie >Cpu0 : 24.8%us, 75.2%sy, 0.0%ni, 0.0%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st >Mem: 2928404k total, 604280k used, 2324124k free, 17800k buffers >Swap: 0k total, 0k used, 0k free, 338536k cached > > PID VIRT RES NI %CPU TIME+ S COMMAND > 2078 5728 1700 0 97.3 24:32.14 R mdadm --monitor --scan -f --pid-file=/var/run/mdadm/mdadm.pid > 3031 107m 3176 0 0.0 0:44.05 S bash > 1 19356 1600 0 0.0 0:31.68 S /sbin/init > 4718 873m 120m 0 0.0 0:21.58 S /usr/lib/libreoffice/program/soffice.bin --splash-pipe=6 > 429 0 0 0 0.7 0:10.92 S [md3_raid1] > 705 0 0 0 1.0 0:10.39 S [md0_raid1] > 4 0 0 0 0.7 0:09.36 S [ksoftirqd/0] > 709 0 0 0 0.3 0:06.49 S [md2_raid1] > 585 10656 752 -4 0.0 0:04.21 S /sbin/udevd -d mdstat doesn't drop any clues (md0 is boot, md2 is swap, md3 is lvm): ># cat /proc/mdstat >Personalities : [raid1] >md0 : active raid1 sdb2[1] sda2[0] > 204788 blocks super 1.0 [2/2] [UU] > >md2 : active raid1 sdb1[1] sda1[0] > 10238904 blocks super 1.2 [2/2] [UU] > >md3 : active raid1 sda5[0] sdb5[1] > 153598908 blocks super 1.1 [2/2] [UU] > bitmap: 0/2 pages [0KB], 65536KB chunk > >unused devices: <none> right after rebooting i swapoff -a, just to narrow in on what's up. if i leave it idle mdadm is still quiet a few hours later. but as soon as i fire up some app, like libreoffice, mdadm pins the CPU and stays that way. it's way bogged down, but stuff still works. a couple days ago this box froze up. this has been happening since. so probably the md3 raid is corrupted? shouldn't mdstat say something? what do i look at next? should i try removing sda5, and then sdb5? or some other way to know which one is good? or is that just wasting time, do i need to ditch md3&fire up a fresh raid? -------------- next part -------------- An HTML attachment was scrubbed...
