Hello

In pacemaker 3.0.1 and corosync 3.1.10 cluster based on HPE DL345g12 servers, what SBD_TIMEOUT for diskless sbd (hpwdt, /dev/watchdog) should be if SBD_WATCHDOG_TIMEOUT=15s ?

Should I set it as 2 X SBD_WATCHDOG_TIMEOUT, i. e. 30s, or just because it is diskless (hpwdt, /dev/watchdog) I can safely set it 15s too ?

Anton
