hi.

i have a broken filesystem that i have checked with fsck.

here is my error output:
Inode 22161733 has an invalid extent node (blk 88789488, lblk 0) Clear? yes
fsck.ext4: e2fsck_read_bitmaps: illegal bitmap block(s) for /dev/mapper/md2_nas /dev/mapper/md2_nas: ***** FILE SYSTEM WAS MODIFIED *****
e2fsck: aborted
/dev/mapper/md2_nas: ***** FILE SYSTEM WAS MODIFIED *****
echo $?
9

the check cancel always at 88789488.
my os is a ubuntu 12.04 64bit system with the e2fsprogs verions 1.42.5-1ubuntu4

i hope some guys have an idea ;-)

thx.

Can you send us the output of "dumpe2fs /dev/mapper/md2_nas"? See also the "REPORTING BUGS" section of e2fsck for more discussion of useful information.
