[Linux-cluster] rgmanager stop just hangs, clurgmgrd never terminates

[Fernando Lozano]

Arwin,

Doesn't you log shows one node trying to fence the other? Clean_start
prevents that at cluster startup, but on failover the survivor wants to
fence the other. You may need to use fence_ack to let one node belive
the other was fenced if you do not have a real fence device, for example
Dell DRAC or a Network APS.

> Yup, matter of fact, I disabled iptables altogether.  The cluster comes up fine and I have services running once again (this is a test setup btw). Just to let you know I managed to get the cluster in this state when I was doing some failover testing.  I'm just wondering why when I do a /sbin/service rgmanager {stop|restart} it hangs indefinitely.
