Current GIT documentation says

Set watchdog timeout to N seconds. This depends mostly on your storage
latency; the majority of devices must be successfully read within this
time, or else the node will self-fence.

If your sbd device(s) reside on a multipath setup or iSCSI, this
should be the time required to detect a path failure. You may be able
to reduce this if your device outages are independent, or if you are
using the Pacemaker integration.

But it never explains how pacemaker integration affects this timeout
(except that stonith timeout must be at least as high as msgwait == 2
* watchdog timeout). Could someone shed the light?
