I got a few helpful responses from some folks on the mailing list, but
would like to throw things back out ...
I can successfully run raidadd and ckraid, but raidrun always fails with
the message:
md: 09:00: raid array is not clean -- run ckraid
ckraid always appears to complete without errors. I have run ckraid with
--fix, --force-continue, --suggest-failed-disk-mask 0x01,
--suggest-fix-parity, --force-check and a few combinations therein.
Here is my /etc/raidtab
raiddev /dev/md0
raid-level 5
nr-raid-disks 5
nr-spare-disks 0
chunk-size 16
parity-algorithm left-asymmetric
device /dev/sdd1
raid-disk 0
device /dev/sde1
raid-disk 1
device /dev/sdf1
raid-disk 2
device /dev/sdg1
raid-disk 3
device /dev/sdh1
raid-disk 4
Here is /proc/mdstat after I run raidadd /dev/md0
Personalities : [4 raid5]
read_ahead not set
md0 : inactive sdd1 sde1 sdf1 sdg1 sdh1 44419200 blocks
md1 : inactive
md2 : inactive
md3 : inactive
The only message that shows up in the log is
md: 09:00: raid array is not clean -- run ckraid
Just a re-cap. I am running RedHat 5.2, unpatched kernel 2.2.3, md is
compiled as kernel modules, but loads fine using insmod before I attempt
raidadd or anything else. (I also tried a 2.2.6 kernel with the raid
driver compiled in, and got the same results).
Everything was all working grand before a power outage last night.
Any help would be appreciated. As I mentioned before, if you need, I can
pay someone for time if they want to call (phone number below).
