System config:

Dell PE2850 server
(4) 36GB SCSI drives in (onboard) RAID-5

RHEL4-U2
Dell ATI Video Driver update 10/2005

ocfs2-2.6.9-22.ELsmp-1.0.7-1.i686.rpm
ocfs2-tools-1.0.2-1.i386.rpm
ocfs2console-1.0.2-1.i386.rpm

Note that this is a single node cluster, nothing else installed/running except iozone.

I was running some "iozone" tests on the OCFS2 volume for about a day, and the system locked up completely. The following messages were transcribed from the console (nothing written to /var/log/messages):

usb4-2: device not accepting address 4, error -71
(11,1): o2hb_write_timeout: 164 ERROR: heartbeat write timeout to device sda6 after 12000 miliseconds (11,1): o2hb_stop_all_regions: 1724 ERROR: stopping heartbeat on all active regeons Kernel Panic - not syncing: ocfs2 is very sorry to be fencing the system by panicing

Questions:
What does all this mean?
Why is nothing getting written to /var/log/messages?
If this software really ready for prime time (honestly...)?

thanks,
