dlmglue fixes
David,
So here are the two patches. Remove all patches that you have and apply
these.
The first one is straight forward.
The second one will hopefully fix the livelock issue you have been
encountering.
People reviewing the patches should note that the second one is slightly
different than the one I posted earlier. It removes the BUG_ON in the if
condition where we jump to update_holders. The

hang with fsdlm
Using fsdlm/ocfs2_controld.cman, I've rerun the test I've been having problems
with on 2.6.30-rc1. After running for several minutes in the same directory
on three nodes, the test hangs, and I collect the following information:

[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.

[PATCH 1/4] ocfs2/dlm: Retract fix for race between purge and migrate
Mainline commit d4f7e650e55af6b235871126f747da88600e8040 attempts to delay
the dlm_thread from sending the drop ref message if the lockres is being
migrated. The problem is that we make the dlm_thread wait for the migration
to complete. This causes a deadlock as dlm_thread also participates in the
lockres migration process.
A better fix for the original oss bugzilla#1012 is in testing.

[PATCH 0/62] Ocfs2 updates for 2.6.26-rc1
The following series of patches comprises the bulk of our outstanding
changes for Ocfs2.
Aside from the usual set of cleanups and fixes that were inappropriate for
2.6.25, there are a few highlights:
The '/sys/o2cb' directory has been moved to '/sys/fs/o2cb'. The new location
meshes better with modern sysfs layout. A symbolic link has been placed in
the old location so as to
