 I am also using it in active-active mode, but instead of CLVM i am exporting
the DRBD resource via iSCSI and using multipath in multibus mode from the nodes.
 In this setup there are problems using stonith thought, because it blocks the
access to both paths and multipath reports no active paths, which causes the
GFS to be withdrawn on some of the nodes. So to avoid this i am using the same
(bonded) interface for cluster and DRDBD communication with dont-care (for
DRBD) and leave the fencing to the cluster instead of DRBD, which also avoids
the double fencing from both.
