Are you using multipath's 'queue_if_no_path' (assuming RHEL4 has it)?
Could be LVM's IO to the mpath devices will queue (block) until the
point when you "break the clone" (which makes the paths(s) available).
This seems to be a pretty good solution to the problem - When I set it
to fail_if_no_path via dmsetup, it seemed to work nicely. Any idea how
to set this within a multipaths { multipath { wwid xxxx }} config?
