[Ocfs2-users] kernel BUG at fs/ocfs2/dlm/dlmthread.c:266

[Piotr Teodorowski]

Hi.

We've got yesterday a bug in OCFS2 (see subject).  It freezed the node 
es1prap02 and caused reboot of some (not all) of other nodes belonging to the 
same  ocfs2 cluster. Could you, please, let us know:

* is the above bug known (or maybe alreadey fixed)?
* is it possible to find out why three other nodes rebooted? It seems, that it 
can be another bug near 'quorum test' in our OCFS2 version.  Am I right?


our configuration:
O2CB_HEARTBEAT_THRESHOLD=31
O2CB_IDLE_TIMEOUT_MS=30000
O2CB_KEEPALIVE_DELAY_MS=2000
O2CB_RECONNECT_DELAY_MS=2000

dist debian lenny
ocfs2-tools 1.4.1-1
kernel 2.6.26-2-amd64
