Hi Michael,
Yes, currently the best way is to copy out data as much as possible and
recreate the ocfs2 volume, then restore back the data.
I haven't encountered this issue before and don't know which case can
lead to it, so I'm sorry I can't give you the advice which can avoid
this issue.
But I
Joseph,
thanks again for your help!
Currently I'm dumping out 4 TB of data from the broken ocfs2 device to
an external disk. I have shut down the cluster and have the fs mounted
read-only on a single node. It seems that the data structures are still
intact and that the file system problems are

Hi Joseph,
thanks for this information although this does not sound too optimistic ...
So, if I understand you correctly, if we had a metadata backup from
o2image _before_ the crash we could have looked up the missing info to
remove the loop from group chain 73, right?
But how could the loop
Hi Michael,
So I think the block of record #153 goes wrong, which points next to
block 4083643392 of record #19.
But the problem is we don't know the right info of the block of record
#153, otherwise we can dd out, edit it and then dd in to fix it.
Thanks,
Joseph

Hi Joseph,
ok, got it! Here's the loop in chain 73:
Group Chain: 73 Parent Inode: 13 Generation: 1172963971

Hi Michael,
It seems that dead loop happens in chain 73. You have formatted using 2K
block and 4K cluster, so each chain should have 1522 or 1521 records.
But at first glance, I cannot figure out which block goes wrong, because
the output you pasted indicates all blocks are different. So I suggest
Hi Joseph,
thanks a lot for your help. It is very much appreciated!
I ran debugsfs.ocfs2 from ocfs2-tools 1.6.4 on the mounted file system:

Could you please use debugfs to check the output?

Hi ocfs2-users,
my first post to this list from yesterday probably didn't get through.
Anyway, I've made some progress in the meantime and may now ask more
specific questions ...

I searched through the mailing list back to 07/2008, and didn't see
this question answered before.
I have 7 systems that use an ocfs2 filesystem. After many months of

File a bugzilla and add the link to that image. (The bz cannot
handle large files.)
The other option is to file a bz and attach the stat_sysdir output.
