My thought on including the drbd nodes in the cluster was to avoid
having to disable the quorum and that it would help reduce the chance of
split brain problems. But this is my first cluster so I'm going on what
seems reasonable without any real experience.
The unordered, uncollocated group has been bashed a bit. But it would
seem to work.
Thanks,
Gregg

Why not run two separate clusters - One for VMs, one for DRBD.
You can create a group containing the resources and have the location
constraint reference the group - You probably want to set the group to
'ordered=false' and 'collocated=false'. That said, if you split your
environment into two clusters you don't need that anyway.

I have two drbd nodes and three nodes that run mostly virtual machines. The
virtual machines can't run on the drbd nodes and drbd can't run on the
visualization hosts. I have location rules and everything works fine. But I get
a long list of Failed Action in the crm_mon output saying that things are not
installed. This is mostly an annoyance but it does make it difficult to spot
real problems because you get used to ignoring the output.
Is there a preferred method to eliminate this?
One other question is about the location rules. I really only have two rules
but have ended up creating multiple instances of the same rule for each
resource. Is there a way to consolidate the rules?
Thanks in advance.
