I have two older desktop pcs that I have set up with drbd, corosync and
pacemaker
No problems there
My hat is off to y'all
Great software
I have set up the colocation rules so that all apps run on one machine or the
other
If I break the communication link between them I get split-brain
So I figure stonith suicide is my only option
When the communication goes down the machine hosting the apps continues to
function properly
The other machine sort of "hangs"

At this point abctest1 is "hung"
The machine still functions but corosync will not shutdown nor will is
reestablish communication after the link is is connected
A pkill -9 cocosync is required to bring it down
Is the how suicide is supposed to behave
