Hi,

  It looks like rhcs_fence is being called repeatedly:

  Starting at line 23, we see that it start up:

Feb  3 17:48:13 wsguardian1 rhcs_fence: 74; Attempting to fence peer
using RHCS from DRBD...
...

  Then at line 42, it starts again:

Feb  3 17:48:13 wsguardian1 rhcs_fence: 74; Attempting to fence peer
using RHCS from DRBD...

  It seems to be called five times, and never finishes. Without a
successful exit, DRBD will hang.

Can you share your DRBD configuration files please? The 'rhcs_fence'
agent was tested on RHEL/CentOS 6.x and DRBD 8.3 only. If there is a
patch needed to make it work on 8.4, I would like to sort it out and get
it applied.
