First I would apologyze for my bad english speeking, but I will
try to do my best to explain my problem.
I'mrunning a two node ocsf2 cluster and tonight my filesystem stop
working dmesg give me this:
[ 3629.392558] ocfs2: Unmounting device (147,10) on (node 0)
[ 3642.161107] o2dlm: Nodes in domain 30E3C79CDAB54C6981FECA29F8668FD7: 0

[ 3652.743210]
[ 3652.743212] File system is now read-only due to the potential of on-disk corruption. Please run fsck.ocfs2 once the file system is unmounted.

[ 3652.743830] OCFS2: ERROR (device drbd10): ocfs2_validate_inode_block: Invalid dinode #6806080: OCFS2_VALID_FL not set
[ 3652.743832]
[ 3652.743834] (ls,24696,3):ocfs2_read_locked_inode:493 ERROR: status = -22
this messages appears directly after trying to list the mounted directory
which give me this output:
# ls /mnt/nfs/htdocs/
ls: impossible d'accéder à /mnt/nfs/htdocs/apache: Permission non accordée
ls: impossible d'accéder à /mnt/nfs/htdocs/postfix: Permission non accordée
total 0
d????????? ? ? ? ? ? apache
drwxr-xr-x 2 root root 3,9K 4 févr. 2011 lost+found
from now I can't access to any data stored on the filesystem.
I run fsck.ocfs2 and it give me this output:
the first try give me nothing because it wasn't able to open DLM:
# fsck.ocfs2 -f /dev/drbd10
fsck.ocfs2 1.6.4
fsck.ocfs2: Could not open dlm directory while initializing the DLM
so I try this:
# fsck.ocfs2 -fFn /dev/drbd10
fsck.ocfs2 1.6.4

not sure what I have to do to recover my data, perhaps someone
on this list will be able to give me some help to solve my issue?
Thanks in advance
