Hi all, 

i am new to ocfs2. 

currently i am playing with ocfs on debian6 wich ocfs2 1.4. 
and also 
Oracle Enterprise Linux 5 & 6 with OCFS 1.6. 

The volume reside on an Dell MD3220i. 
When i set the active controller to offline, the client should initiate an 
failover to the second controller. 
this works, of only one clustermember is active for ocfs. 
At the moment there are two clustermembers, at least one crashes often both 
clients does a reboot. 

The the timeouts are the following 
O2CB_ENABLED=true 
O2CB_BOOTCLUSTER=debianocfs 
O2CB_HEARTBEAT_THRESHOLD=61 
O2CB_IDLE_TIMEOUT_MS=90000 
O2CB_KEEPALIVE_DELAY_MS=2000 
O2CB_RECONNECT_DELAY_MS=2000 

in the attachment i have the Dell multipath.conf. 
failback is already to manual, so it does least controller switches. 

what could be the reason for the crashes? 

best regards 
thomas
