but they have different GUIDs
why would you mount the partitions on the same mountpoint in the first
place
shouldn't you have 1 device only with th failover stuff underneath
or have 2 devices and 1 virtual device that gets the fall back
in theory you shoulndn't have to care/worry about config slots being
there still, we don't have a tool to remove slots, but is should also
not be needed, the guid is in the /etc/ocfs.conf file
and when you mount it will use the slot that has that guid in there
