Your configuration seems to have way too many moving parts and since you are
making routing changes when the nodes become primary it is difficult to
ensure that it will actually work based upon the monitoring you are doing
when it is passive.

In most cluster tutorials, for simplicity, iptables is turned off.
Funny thing is that iptables is what I want to configure in HA cluster
(as redundant firewalls).

It may be a bit late given that you've just created your own script,
but you can grab the check-cluster (and maybe check-drbd) scripts from
the gno-cluster-tools package at ftp://ftp.gno.org/pub/tools/cluster-tools
If I have a cluster that is not otherwise monitored, I run those
every three hours
I have both two-node clusters that use drbd with local disk (no SAN)
and a three node cluster where one node is always in standby and
is just used for quorum.
IMO, if you are using drbd-on-local-disk and have proper fencing
support, the three node case in its current incarnation is more
trouble

I ran into a similar behavior with an earlier version of glusterfs
on raw disk (not DRBD). In that case it was a bug in gluster
that, although the nodes were supposed to be operating in a
mirror configuration, the one remaining node would refuse to
service requests after the other node was

Excellent.
But if I pull the power cable without a regular shutting down,
the powerless node gets status UNCLEAN (offline) and the

I would contend that would be correct behavior

I suspect that it's a similar situation with heartbeat. The problem is
