Just a small note: that's the kind of lock-ups I was seeing too,
client induced, disks completely inaccessible, no error/dmesg log.

I have now updated to RHEL 5.4 and I am lock free so far after heavy
testing and lots of software building that was previously hanging my

I have also enabled magic-sysrq so I can get at least some info should
the hangs re-occur. I would recommend everyone else with logless hangs
to do the same if possible.

Kudos to all those involved in this bug-hunt fest, it can only serve
to make glusterfs stronger!
