[Ocfs2-users] Kernel Panic, Server not coming back up

I have a relatively new test environment setup that is a little different
from your typical scenario.  This is my first time using OCFS2, but I
believe it should work the way I have it setup.

All of this is setup on VMWare virtual hosts.  I have two front-end web
servers and one backend administrative server.  They all share 2 virtual
hard drives within VMware (independent, persistent, & thick provisioned).

Everything works great and the way I want, except occasionally, one of the
nodes will crash with errors like the following:

end_request:  I/O error, dev sdc, sector 585159
Aborting journal on device sdc1
end_request:  I/O error, dev sdc, sector 528151
Buffer I/O error on device sdc1,  logical block 66011
lost page write due to I/O error on sdc1
(2848,1):ocfs2_start_trans:240 ERROR: status = -30
OCFS2: abort (device sdc1): ocfs2_start_trans: Detected aborted journal
Kernel panic - not syncing: OCFS2:  (device sdc1): panic forced after error

 <0>Rebooting in 30 seconds..BUG: warning at
arch/i386/kernel/smp.c:492/smp_send_reschedule() (Tainted: G    )

The server never reboots, it just sits there until I reset it.  The cluster
ran fine without errors (for a week or two) and now that I upgraded to the
latest kernel/ocfs2 it's happening almost daily.  The disks are fine,
it's
on a LUN on a SAN with no problems and I unmounted all the partitions and
ran fsck.ocfs2 -f on both drives from all three nodes (one at a time) and
it found no errors.

This morning it happened again and now after a reset the server will not
boot up at all, just sits there on "Starting Oracle Cluster File System
(OCFS2)".  These servers are all running OEL 5.4 with the latest patches
installed.

Here's the setup:# cat /etc/ocfs2/cluster.conf 
cluster:
	node_count = 3
	name = qacluster

node:
	ip_port = 7777
	ip_address = 10.10.220.30
	number = 0
	name = qa-admin
	cluster = qacluster

node:
	ip_port = 7777
	ip_address = 10.10.220.31
	number = 1
	name = qa-web1
	cluster = qacluster

node:
	ip_port = 7777
	ip_address = 10.10.220.32
	number = 2
	name = qa-web2
	cluster = qacluster

Any suggestions?  Is there anymore data I can provide?

Thanks for any help.

It is having problems doing ios to the virtual devices. -5 is EIO.
