You may want to increase stonith-timeout a bit further, to increase the
difference between msgwait (the time that sbd will wait before
returning) and the cluster allowed time for that. But 10s should not be
too little, actually ...

Why the group? You can drop that line fine.

No, actually, it should treat the fence action as completed after
"msgwait" seconds; "stonith-timeout" is the time pacemaker allows for
that fence operation to complete maximum before considering it failed. I
think you got these two confused.

Okay, this is weird. You've se the timeout to 100s, not 90s; that's what
should be passed in here.
If msgwait is approximately the same as st_timeout, since st_timeout
starts counting when the process is kicked off and msgwait after the
message has been written to disk, it is very probable that it never can
complete successfully.

You're hitting a timeout; which you shouldn't, given the bits of the
configuration you've posted.
Is the above your whole CIB? Are you setting any other timeouts
somewhere that might override the 100s timeout you set?
