Hi Vernard,

I'm not very knowledgeable in the ways of lvm, however, you may want to
check to make sure that lock_dlm.ko is loaded (by using lsmod).
I don't know the code, but I'm guessing it's trying to create a lock
space by opening one of the dlm kernel devices (/dev/dlm*) which should
be controlled by the lock_dlm device driver.  If that's not loaded, it
will fail.

Also, make sure the second box can physically see the SAN in
/proc/partitions.  I've seen some weird things like this happen when a
cluster comes up but some of the nodes can't physically access the SAN.

I hope this helps.
