I'm setting up a 4-node cluster where 2 of the nodes will run an
active/active DRBD and the other two nodes will be available in case one
of the "active" nodes fails.
I can almost get this working fine. But, what I can't seem to figure
out is how to restrict the DRBD Masters to only certain combination of
nodes.
I want the replication to happen between:
pzsmbr01 and pzsmbr51
or
pzsmbr02 and pzsmbr51
or
pzsmbr01 and pzsmbr52
or
pzsmbr02 and pzsmbr52
Because I share the SAN disks between the following node combinations, I
do NOT want the DRBD Masters to wind up on:
pzsmbr01 and pzsmbr02
or
pzsmbr51 and pzsmbr52
If there's not an easy way to restrict the MS resource like that and
getting rid of the SAN sharing would make this setup easier, then I'd be
happy to. But, I must have the ability to move a group of resources
around the cluster freely and I don't think I can do that with DRBD
stacking (can I???).
Thanks for any help.
Leland
