Hi all,
I have a pernennial problem with a raid array (which contains a 400GB
filesystem 72% full.
Since its raid 1 I am bemused that I keep getting file-system errors every 2 or
threee days on reboot (requiring a manual fsck).
The kernel log shows (e.g):

Is anyone able to reasonably decipher this?
I recently upgraded the filesystem from ext3 to ext4 (via "appropriate
incantation" of tune2fs).
This made not the slightest difference.
Strangley, after the fscks has fixed things (mainly dup allocated blocks) I
never appear to have lost anything (!).
Any (reasonably polite) suggestions gratefully received. In particuylar - how
to match the ata no. given with one of my actual disks
filesystems mounted as follows:
/dev/mapper/vg_waverley-lv_root on / type ext4 (rw)
proc on /proc type proc (rw)
sysfs on /sys type sysfs (rw)
devpts on /dev/pts type devpts (rw,gid=5,mode=620)
tmpfs on /dev/shm type tmpfs (rw,rootcontext="system_u:object_r:tmpfs_t:s0")
/dev/sda1 on /boot type ext4 (rw)
/dev/mapper/vg_waverley-lv_home on /opt type ext4 (rw)
/dev/md1 on /home type ext4 (rw)
/dev/md0 on /multimedia type ext3 (rw)
none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw)
fusectl on /sys/fs/fuse/connections type fusectl (rw)
gvfs-fuse-daemon on /home/andyp/.gvfs type fuse.gvfs-fuse-daemon
(rw,nosuid,nodev,user=andyp)

md1 is the offending mirror.
System is FC14: Fedora release 14 (Laughlin)
(But I was getting this with FC11 prior to an upgrade)
