 Posted: Tue Dec 13, 2005 10:15 pm Post subject: Kernel Panic when simulating drive failure in software raid1 |
 |
|
I have 64bit gentoo running on a dual xeon 3.2ghz machine, with software raid level 1, md compiled into the kernel instead of as a module.
All is fine and dandy, the raid is running, but if I open the case, and unplug a drive, either drive, the kernel panics.
Raidtab:
| Code: |
# /boot (RAID 1)
raiddev /dev/md0
raid-level 1
nr-raid-disks 2
chunk-size 32
persistent-superblock 1
device /dev/sda1
raid-disk 0
device /dev/sdb1
raid-disk 1
# / (RAID 1)
raiddev /dev/md2
raid-level 1
nr-raid-disks 2
chunk-size 32
persistent-superblock 1
device /dev/sda3
raid-disk 0
device /dev/sdb3
raid-disk 1
# /home (RAID 0)
raiddev /dev/md1
raid-level 1
nr-raid-disks 2
chunk-size 32
persistent-superblock 1
device /dev/sda2
raid-disk 0
device /dev/sdb2
raid-disk 1

fstab:
| Code: |
# This file is edited by fstab-sync - see 'man fstab-sync' for details
# /etc/fstab: static file system information.
#
# noatime turns off atimes for increased performance (atimes normally aren't
# needed; notail increases performance of ReiserFS (at the expense of storage
# efficiency). It's safe to drop the noatime options if you want and to
# switch between notail / tail freely.
#
# See the manpage fstab(5) for more information.
#
# <fs> <mountpoint> <type> <opts> <dump/pass>
# NOTE: If your BOOT partition is ReiserFS, add the notail option to opts.
/dev/md0 /boot ext3 noatime 1 2
/dev/md2 / reiserfs noatime 0 1
/dev/md1 none swap sw,pri=0 0 0
/dev/cdroms/cdrom0 /mnt/cdrom iso9660 noauto,ro 0 0
#/dev/fd0 /mnt/floppy auto noauto 0 0
# NOTE: The next line is critical for boot!
proc /proc proc defaults 0 0
# glibc 2.2 and above expects tmpfs to be mounted at /dev/shm for
# POSIX shared memory (shm_open, shm_unlink).
# (tmpfs is a dynamically expandable/shrinkable ramdisk, and will
# use almost no memory if not populated with files)
shm /dev/shm tmpfs nodev,nosuid,noexec 0 0

Why does the kernel panic when the drive (either) is unplugged instead of continuing to run as it should?
Many thanks,
Michael
