Run with -fn. It is non destructive. Also use the latest fsck. 1.4.4 I believe.

simple question: how can I execute a fsck.ocfs2 /dev/sdf?
All I get is

whereas it was starting when using ocfs2 rpms 1.4.3-3 with same releases of

Any idea ?
Thanks a lot.

I thought that ocfs2 was only capable of node self-fencing because
there is no configuration of any fencing device (i.e.

This workload will benefit a lot with the indexed directories available in
ocfs2 1.6 (and mainline and sles11).
The other thing to check is the amount memory in the virtual machines.
File systems need memory to cache the inodes. If memory is lacking,
the inodes are freed and

do i need an other fsck.ocsf2 directly ?

Dump the following:

This will save the errant inode.
Then run fsck -fy. Hopefully that will fix

This is mentioned in the doc/FAQ. Ocfs2 does not update the mtime on disk for
non-extending directio writes. The correct times you are seeing are only in
cache. We do this to allow multiple nodes to r/w concurrently to the same file.
Having said that, in mainline we have recently added a mount
ping_long tests the fcntl() user locks.
ocfs2 supports clustered fcntl() locking with cman and pacemaker
cluster stacks. Not with o2cb.
ocfs2 supports clustered flock() with all stacks. o2cb, cman and pacemaker.
