o2dlm join and leave messages are more than informational as they are required is debugging locking issues. This patch changes them from KERN_INFO to KERN_NOTICE. Signed-off-by: Sunil Mushran <sunil.mushran at oracle.com> --- fs/ocfs2/dlm/dlmdomain.c | 6 +++--- 1 files changed, 3 insertions(+...

The Lock Value Block (LVB) of a DLM lock can be lost when nodes die and the DLM cannot reconstruct its state. Clients of the DLM need to know this. ocfs2's internal DLM, o2dlm, explicitly zeroes out the LVB when it loses track of the state. This is not a standard behavior, but ocfs2 has always relied on it. Thus, an o2dlm LVB is always "valid". ocfs2 now supports both o2dlm and fs/dlm via the stack glue. When fs/dlm loses track of an LVBs state, it sets a f...

Hi, I have a 2 nodes ocfs2 cluster running UEK 2.6.32-100.0.19.el5, ocfs2console-1.6.3-2.el5, ocfs2-tools-1.6.3-2.el5. My problem is that all the time when i try to run /etc/init.d/o2cb stop it fails with this error: Stopping O2CB cluster CLUSTER: Failed Unable to stop cluster as heartbeat region still active There is no active mount point. I tried to manually stop the heartdbeat with

Hi, we are using a SLES10 Patchlevel 3 with 12 Nodes hosting tomcat application servers. The cluster was running some time (about 200 days) without problems. Recently we needed to shutdown the cluster for maintenance and experianced very long times for the umount of the filesystem. It took something like 45 minutes each node and filesystem (12 x 45 minutes shutdown time). As a result the planned

There are two problems in dlm_run_purgelist 1. If a lockres is found to be in use, dlm_run_purgelist keeps trying to purge the same lockres instead of trying the next lockres. 2. When a lockres is found unused, dlm_run_purgelist releases lockres spinlock before setting DLM_LOCK_RES_DROPPING_REF and calls dlm_purge_lockres. spinlock is reacquired but in this window lockres can get reused.
