Re: [ClusterLabs] Change SBD Disk to VCenter Stonith
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.

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.
