Do:
# echo "ls -l //" | debugfs.ocfs2 /dev/sdX
This will list the sizes of the system files. Email me the info.

I created another 50 GB OCFS2 file system with the same parameters (16k
cluster 4k block) and copied the contents of the original file system.
My 26GB of data only takes up 38GB now (43 GB on the original file
system). After I delete all the contents of the new file system, there
is still 3.7 GB used. Any ideas?

I unmounted the file system from each node and ran the fsck.ocfs2 on it.
That cleaned up the orphan_dirs but I did not get my 17 GB of space
back. Any other suggestions? Am I going to have to
backup,format,restore to fix this?

Yes.

When I stat the only file listed in //orphan_dir:0002 it shows 0
clusters. There are only directories listed in //orphan_dir:0000 and
none of the directories have contents. So my next courses of action
(since I don't know what has these unlinked files opened) would be to
stop every process accessing this file system? Possibly umount/mount
the file system? would fsck.ocfs2 clean this up?

Another node or that node itself.
As far as the filesize goes, "ls -l" does not give the ondisk size.
Do "stat <inodenum>" on the unlinked files and see the "Clusters".

There has been a lot of file system activity recently.
I have files in orphan_dir:0000 and orphan_dir:0002. But that
doesn't
seem to account for the 17 GB missing. The truncate logs seem clean.
So having files in orphan_dir:0000 is telling me that the node in
slot
0
deleted files and another node(s) still has the file open, correct?

Did you remove some large files recently? If so, check the orphan_dir
and truncate_log for all the slots.
1. Start debugfs:
# debugfs.ocfs2 /dev/sdX
2. List system directory:
> ls -l //
3. List files in all orphan_dir(s):
> ls -l //orphan_dir:0000
If there are files, means some process in the cluster is still using
that file.
4. stat all trancate_log(s):
> stat //truncate_log:0000
I will be surprised if you see any bits here. If there are, do
"sync;sync;sync;" on the
appropriate node.
5. You can find the appropriate node by dumping the slotmap:
> slotmap
Find the slot-to-nodenum mapping. Do the sync on that node.
For this and more, refer to the on-disk format support guide.

Hi all.
I have a 50 GB OCFS2 file system. I'm currently using ~26GB of space
but df is reporting 43 GB used. Any ideas how to find out where the
missing 17GB is at?
The file system was formatted with a 16K cluster & 4K block size.
Thanks,
Matt
