Hi all,

i made a test with a OEL 5.8 and OEL 6.3 (currently withing VMware) against a iSCSI MD3220 with OCFS.
(cause a customer question)

The system is running and ocfs 1.6 and ocfs 1.8 are within the group.
But when i set the owning controller offline, after a while OEL6.3 reset.
The timeouts got already defined to 61, according to metalink 603038.1.

the system complains about several:
