Hello Christoph,

Why do you think that ? Could you be more prolix about this change and
what are the pros and cons of making this change ? An example on how
you're setting up your cluster using sbd and watchdog would be also good
to corroborate your request.

From:

https://wiki.clusterlabs.org/wiki/Using_SBD_with_Pacemaker

I have:

"""Ensure that the sbd daemon is running on a node before starting the
cluster services. The best approach is generally to enable it to start
at boot. (The cluster can't manage the sbd daemon as a cluster
resource.) There are two flavors of SBD, sbd for cluster nodes, and
sbd_remote for Pacemaker Remote nodes. Here we use sbd as an example,
but for Pacemaker Remote nodes, replace sbd with sbd_remote:"""

Note: sbd has to start before corosync and pacemaker. It would be good
to have watchdog already working, so you're probably right... but that
change should be done in sbd.service and not watchdog (as watchdog is a
"generic" service that serves other purposes than pacemaker/fence-
agents).

and

"""With watchdog-only SBD, the cluster must have true quorum. Thus, it can only 
be used in a cluster with three or more nodes, or a two-node cluster with 
external quorum (such as corosync using qdevice with a third node).
Configure the basic setup on every node as described above.
Select a recovery interval (in seconds) that is greater than 
SBD_WATCHDOG_TIMEOUT in /etc/sysconfig/sbd."""

I assume the ordering has something to do with unfencing (from fence_sbd
+ watchdog setup) but I also know that those type of unfencing (like
fence_mpath and fence_iscsi) are not supported "automatically" (meaning
that any time there is a cluster split, a manual intervention is
required).

Looking forward to reading more about your request.

Thanks
