Hello Andrew/All,
Thanks. It works again. This is what I had running after I wanted to
move on to a 3-node cluster.
Two drbd-nodes for storage and one as a webserver via NFS.
So i have to set the cluster back to non-symmetric and fiddle around
with location constraints to get the
tho drbd-nodes back to where they are now. Right?
PS I'm a newbie to this so sorry this stupid mistake!
Greetings,
Kees Koehoorn
