Is it possible to get corosync to use the private network and stop trying
to use the LAN for cluster communications? Or am I totally off-base and am
missing something in my drbd/pacemaker configuration?
Absolutely! When I setup my two-node cluster recently I did exactly
that. If you are using 'pcs' to manage your cluster, ensure that you
add the 'addr=' parameter during 'pcs host auth' so that Corosync and
the layers above it will use that address for the host. Something
like:
$ pcs host auth cluster-node-1 addr=192.168.10.1 cluster-node-2
addr=192.168.10.2
You can even set multiple rings so corosync can rely on both:
$ pcs host auth \
cluster-node-1 addr=192.168.10.1 addr=10.20.30.1 \
cluster-node-2 addr=192.168.10.2 addr=10.20.30.2
Hi,
Just a little correction.
The 'pcs host auth' command accepts only one addr= for each node. The
address will be then used for pcs communication. If you don't put any
addr= in the 'pcs cluster setup' command, it will be used for corosync
communication as well.
However, if you want to set corosync to use multiple rings, you do that
by specifying addr= in the 'pcs cluster setup' command like this:
pcs cluster setup cluster_name \
cluster-node-1 addr=192.168.10.1 addr=10.20.30.1 \
cluster-node-2 addr=192.168.10.2 addr=10.20.30.2
If you used addr= in the 'pcs host auth' command and you want the same
address to be used by corosync, you need to specify that address in the
'pcs cluster setup' command. If you only specify the second address,
you'll end up with a one-ring cluster.
Regards,
Tomas
Then, compare (but do not edit!) your "/etc/corosync/corosync.conf" on all
nodes.
Regards,
