I see this was the root disk. Did you determine where the disk space went? Where there bloated log files somewhere? 

What does snaptest do?

Was there a reason that let you to assign this to device-mapper-multipath, and not something more generic?

Please take a look at /var/log/messages, and post it if possible.

Comment 3 Suzanne Logcher 2011-10-06 18:41:48 UTC
Since RHEL 6.2 External Beta has begun, and this bug remains
unresolved, it has been rejected as it is not proposed as
exception or blocker.
               
Red Hat invites you to ask your support representative to
propose this request, if appropriate and relevant, in the
next release of Red Hat Enterprise Linux.

This bug has been in needinfo for four and a half years. Closing.
