When you use RAW, you are using it for only datafiles and
not binary homes. So you are not comparing apples-to-apples.
Bottomline, the fs requires a stable shared disk to work. Any
flakiness in the shared disk, and you will encounter the errors
that you are experiencing.

Mark,
Unfortunately that's not an option. Because I am doing it for
non-busines/educational purpose & I/we don't have money to go for
anything except FireWire. Moreover, if I use only RAW partitions of
that FireWire drive, everything works fine. So, it's clearly an OCFS2
issue. Can you please ask your enginners to look into this if they
have time?
I heard many people (e.g. Jeff Hunter who wrote how to do it) have
implemented FireWire/OCFS2/CRS/RAC witthout any issue -- and if that
is the case, why wouldn't it work for us?
Thanks for your help.

Where did you get the drivers for a shared firewire disk from? Can
you try
iscsi or aoe for your shared disk? The shared-disk firewire stuff
is known
to be flakey and was only ever intended for quick proto-typing.
Actually, a while ago one of our engineers was consistently getting
corruptions on every block which would change the inode signature from
"INODE01" to "KNODE01". Getting him off of the firewire stuff
solved that
issue (hardware and ocfs2 version stayed the same). I'd venture to
guess
that you're hitting the same type of problem.
