Sounds/looks a lot like DRBD.  The config snip shown is about the same for
both..  But I don't think it is DRBD, but rather based on DRBD...

DRBD generally (configurable) will restart a rebuild as soon as a host
comes up and contacts the other host(s), assuming it can.  If it can't
for any reason,  then it of course sits and waits for manual intervention
or for something to change so it can continue.
