Diagnosing some OCFS2 error messages
...performing various stress tests. My current exercise involves
writing to files using a shared-writable mmap() from two nodes. (Each
node mmaps and writes to different files; I am not trying to access
the same file from multiple nodes.)
Both nodes are logging messages like these:

[PATCH] ocfs2: flush dentry lock drop when sync ocfs2 volume.
In commit ea455f8ab68338ba69f5d3362b342c115bea8e13, we move the
dentry lock put process into ocfs2_wq. This is OK for most case,
but as for umount, it lead to at least 2 bugs. See
http://oss.oracle.com/bugzilla/show_bug.cgi?id=1133 and
http://oss.oracle.com/bugzilla/show_bug.cgi?id=1135. And it happens
easily if we have opened a lot of inodes.
For 1135, the reason is that during umount will call

[PATCH] ocfs2: Don't delete orphaned files if we are in the process of umount.
Generally, orphan scan run in ocfs2_wq and is used to replay orphan
dir. So for some low end iscsi device, the delete_inode may take
a long time(In some devices, I have seen that delete 500 files will
take about 15 secs). This will eventually cause umount to
livelock(umount has to flush ocfs2_wq which will wait until orphan
scan to fini...

OCFS2 problems when connectivity lost
...s to shut the resources down on that node,
but fails to stop the OCFS2 filesystem resource stating that it is "in use".
*Both* OCFS2 nodes (ie. the one with the network down and the one which
is still up in the partition with quorum) hang with dmesg reporting that
events, ocfs2rec and ocfs2_wq on *both* nodes are "blocked for more than
120 seconds".
When the network is operational, umount by hand works without any
problems, because for the testing scenario there are no services running
which are keeping the mountpoint busy.
Configuration we used is pretty much from "C...

[PATCH 0/5] OCFS2 quota fixes
Hello,
the following series of patches fixes some issues with OCFS2 quotas.
The first patch modifies VFS quota locking, the next patch uses the
fact to simplify OCFS2 quota locking and solves a few deadlock issues.
The third and the fourth patches fix another possible deadlocks in OCFS2
quota code and the last patch is a minor cleanup.

[PATCH] ocfs2: Plugs race between the dc thread and an unlock ast message
This patch plugs a race between the downconvert thread and an unlock ast message.
Specifically, after the downconvert worker has done its task, the dc thread needs
to check whether an unlock ast made the downconvert moot.
