Subject: degraded raid5 at bootup
Date: Fri, 13 Aug 2004 12:49:18 -0700 [thread overview]
Message-ID: <411D1B3E.9050306@tupshin.com> (raw)
I have a 5 disk raid5 using autodetect partitions. If I have a clean
array when I shut down, I always have a degraded array with one disk
removed when I boot back up. Below I include the relevant dmesg output.
hdi1 is always the problem. If I do a "mdadm -a /dev/md0 /dev/hdi1",
then the array rebuilds without a problem, and runs clean until I reboot
again. Any suggestions?
Kernel is 2.6.8-rc2-mm2, but I've tried it with a few other recent
kernels (mm and not) and all have the same problem. Distro is Debian Sid.
