This email is also sent to cluster-devel at redhat.com. Since this issue is about both dlm and ocfs2, I send the email here to look for help from upstream. This is an already known issue. on ocfs2 with user space cluster stack, run the test script from http://people.redhat.com/~teigland/make_panic on the mounted ocfs2 volume from 2 nodes simultaneously, the access to ocfs2 volume on both nodes

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: bull-01 ------- 3053 S< [ocfs2dc] ocfs2_downconvert_thread 3054 S< [dlm_astd] dlm_astd 3055 S< [dlm_scand]

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.

Commit 1c66b360fe262 (Change some lock status member in ocfs2_lock_res to char.) states that these fields need to be signed due to comparision to -1, but only changed the type from unsigned char to char.

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
