I think the source of the issue is this: Nov 2 23:12:03 nfsserver1 drbd(drbd)[4673]: ERROR: r0: Called /usr/sbin/crm_master -Q -l reboot -v 10000 Nov 2 23:12:03 nfsserver1 drbd(drbd)[4673]: ERROR: r0: Exit code 107 Nov 2 23:12:03 nfsserver1 drbd(drbd)[4673]: ERROR: r0: Command output: Nov 2 23:12:03 nfsserver1 lrmd[2163]: notice: drbd_monitor_60000:4673:stderr [ Error signing on to the CIB service: Transport endpoint is not connected ] It seems the drbd resource agent tries to use crm_master to promote the clone but fails because it cannot "sign on to the CIB service". Does anybody know what that means?
