Hi all,
I configured GFS over DRBD (active-active) with RHCS and IPMI as fence device.
When I try to mount my GFS resource, my interconnect interface goes
down and one node is fenced. This happen every time.
DRBD joins and become primary...

Consider that if I don't mount GFS, the node is not fenced and the
failover domains becomes active.
So, I guess the problem is in GFS... and not for example with the NIC.
Here is my configuration:
