Hi,
at the moment i am evaluating RHCM and Heartbeat V2 to refine our
Heartbeat V1 Cluster.
My question as in the subject:
Is it possible to use GFS without the RHCM ?
Not sure. You don't need rgmanager, but you need
fencing/membership/etc.
Nothing precludes you from running HBv2 in addition to RHCM+GFS.
Providing you arrange for "non-overlapping areas of concern" -
otherwise you could get the two cluster managers trying to pull the
cluster in opposite directions.
A third option is to run the CRM^ (the part that is new with Heartbeat
v2) on top of OpenAIS so that the CRM and GFS are sharing the same
"membership/etc" infrastructure.
^ Now its own project called Pacemaker and with support for both
cluster stacks.
For more details, see: http://clusterlabs.org
I want to build a 2 node cluster with drbd activ/activ and RHCM/GFS
or
Heartbeat V2 with filesystem OCFS or GFS.
Here's how to get a 2-node DRBD setup going w/ RHCM (without HBv2):
