Subject: 2.5.27 raid1 bug...
Date: Mon, 22 Jul 2002 12:23:35 -0600 [thread overview]
Message-ID: <3D3C4DA7.5DC4550C@liveglobalbid.com> (raw)
Okay, I've isolated a problem with raid1/md under 2.5.27...
Scenario:
/dev/hda2 and /dev/hdb2 are unused partitions.
/etc/raidtab:
raiddev /dev/md0
raid-level 1
nr-raid-disks 2
chunk-size 64k
persistent-superblock 1
nr-spare-disks 0
device /dev/hda2
raid-disk 0
device /dev/hdb2
raid-disk 1
mkraid /dev/md0
Fails with a kernel panic. A bit of searching finds that this chunk of
code (md.c, about line 850):
rdev = list_entry(&mddev->disks.next, mdk_rdev_t, same_set);
sb = rdev->sb;
memset(sb, 0, sizeof(*sb));
Is failing. sb is == 1 !!
Anyone got any ideas?
