Hi,
I have some problems building the latest sbd from the repo, it seems like
the file 'tests-opt.m4' might be missing?

In the default Mailman config unsubscribe score seems to be 5.0,
but you can only get 1.0 per day if there are bounces.
Also score is reset to 0 if there

It would be strange if AWS control API for node1 would be serialized with

Yes, it is tricky but should be possible by extending the LVM or
shrinking the filesystem by the required DRBD size. Also I think

Perhaps keepalived can be configured to only setup IPVS (no VRRP) and
than added to pacemaker as a systemd service.

As this page explains, fencing is required for the cluster to behave
correctly:

Since you have three nodes you may want to use the third node as QDevice
