[ClusterLabs] Change SBD Disk to VCenter Stonith

[Dileep V Nair]

Hello Klaus,

	Thanks for the suggestion. I tried both ways, but even then pacemaker
service is not starting because there is a dependency on SBD service, which
does not start without the SBD disk. I am planning to try uninstalling SBD
service itself and see if that removes the dependency. Any suggestion on
how to remove the dependency without actually uninstalling service will be
helpful.

Thanks & Regards

      Hi,

      I have a running cluster with Stonith configured as SBD. Now I would
      like to remove the SBD disks and move to VCenter Stonith. After
      removing the SBD disk, I am not able to start pacemaker because of
      the dependant SBD service which was configured during
      ha-cluster-init. What is the best way to remove SBD disk from the VM.



The other way round would probably be more handy like first remove SBD
configuration and
afterwards remove the disk from the VM.
But I guess it would probably be quickest to remove the disk from the
SBD-config-file
(e.g. /etc/sysconfig/sbd) to get pacemaker-service up again. Or you just
disable SBD-service
(e.g. systemctl disable sbd). In both cases the SBD fencing resource would
probably moan
on monitoring but that shouldn't prevent you from adapting the stonith
configuration.
