Thread: LVM/software RAID partition mount problem (11.10)

hi all,

i've tried best fix , find solution, i've run out of ideas , places go. upgraded 10.04 11.10 , had no problems upgrade. system restarted afterwards. today, got computer had suffered kernel panic, restarted , started getting error on attempting mount /home lv:

code:

mount: wrong fs type, bad option, bad superblock on /dev/mapper/armitage-home,         missing codepage or helper program, or other error         in cases useful info found in syslog - try         dmesg | tail  or so

the output dmesg | tail is:

code:

[  998.988541] atkbd serio0: unknown key pressed (translated set 2, code 0xd9 on isa0060/serio0).  [  998.988545] atkbd serio0: use 'setkeycodes e059 <keycode>' make known.

i have 2 software-raid 10 pvs in lvm , lvm has 2 lvs 1 /swap , 1 /home. have separate drive / separate of (at least system still boots...)

i've tried run fsck.ext4 , e2fsck on drive, consistently ends (after hours) error (the exact error message don't have on hand).

if try use backup superblock fsck (either version) get:

code:

fsck.ext4: unable set superblock flags on /dev/mapper/armitage-home

i tried vgcfgrestore on lvm worked, didn't solve problem.

i'm out of ideas.

suggestions?

in case helps (and give bit of bump), error running fsck.ext4 on logical volume is:

code:

error storing directory block information (inode=123105629, block=0, num=228779): memory allocation failed  e2fsck: aborted
