Re: [Pacemaker] KVM VM's on internal DRBD volumes

One of my clusters (fairly old; heartbeat 3.0.0 on openais) runs VMs on Xen, with storage being directly on the drbd device. I noticed a similar problem where manual failovers were fine but cluster-initiated failovers failed. It turned out that setting a start delay on the xen RA solved the probl

It may be a bit late given that you've just created your own script, but you can grab the check-cluster (and maybe check-drbd) scripts from the gno-cluster-tools package at If I have a cluster that is not otherwise monitored, I run those every three hour

Re: [Pacemaker] 3rd node just for quorum

I have both two-node clusters that use drbd with local disk (no SAN) and a three node cluster where one node is always in standby and is just used for quorum. IMO, if you are using drbd-on-local-disk and have proper fencing support, the three node case in its current incarnation is more trouble t

Re: [Pacemaker] MySQL HA-Cluster, error on move

I should also mention that some of the key pieces are having the pid file on local (non-drbd) disk and having your db configured to allow the RA to test the status (per the docs). Having the pid file on drbd storage causes the monitor on the backup node to fail. I don't use a different db data lo

Re: [Pacemaker] How to prevent locked I/O using Pacemaker with Primary/Primary DRBD/OCFS2 (Ubuntu 10.10)

I ran into a similar behavior with an earlier version of glusterfs on raw disk (not DRBD). In that case it was a bug in gluster that, although the nodes were supposed to be operating in a "mirror" configuration, the one remaining node would refuse to service requests after the other node was sto

I've got an RA available for bacula-fd if anyone needs it. It's GPL'd, and if anyone wants to incorporate it into the resource-agents RPM, they are welcome to do so. (The 'anything' RA isn't quite sufficient for bacula-fd.) It is available at: ftp://ftp.gno.org/pub/tools/bacula-contrib S
