We should check dlm->dlm_state under dlm->spinlock though maybe in this case it doesn't hurt.

Hello, We just experienced a hang that looks superficially very similar to http://www.mail-archive.com/ocfs2-users at oss.oracle.com/msg02359.html There are 3 nodes in the cluster ocfs2-1.4.1 rhel 5.2. Versions, uname's in the attached text file which also includes fs_locks dumps and various other diagnostics. The lock up happened when we were restarting a java application that was

Hello, First of all, i am new at the list and i have several questions about ocfs2 performance. Where i am working i am having huge performance problens with ocfs2. Let me tell my envoriment. 3 Xen VirtualMachines withs ocfs2 mounting an LUN exported over iSCSI. ( acctualy 3 LUNS, 3 ocfs2 clusters ) I am not the one who configured the envoriment, but it is making the performance of my MAIL

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

These patches convert the mle list to a hash. The same patches apply on ocfs2 1.4 too. Currently, we use the same number of hash pages for mles and lockres'. This will be addressed in a future patch that will make both of them configurable. Sunil

The changes from the last drop are: 1. Patch 11 removes struct dlm_lock_name. 2. Patch 12 is an unrelated bugfix. Actually is related to a bugfix that we are retracting in mainline currently. The patch may need more testing. While I did hit the condition in my testing, Marcos hasn't. I am sending it because it can be queued for 2.6.30. Give us more time to test. 3. Patch 13 will be useful

All, This is hopefully the final drop of the patches for adding global heartbeat to the o2cb stack. The diff from the previous set is here: http://oss.oracle.com/~smushran/global-hb-diff-2010-10-07 Implemented most of the suggestions provided by Joel and Wengang. The most important one was to activate the feature only at the end, Also, got mostly a clean run with checkpatch.pl. Sunil
