As others have pointed out, the reclock file is crucial unless you
have some other way of avoiding a split brain.  You won't know you need
it until you get a split brain and something gets badly corrupted.

Additionally, as Ronnie mentioned, if the reclock file isn't working
then there's something wrong with your locking, so you have more than a
reclock problem...

peace & happiness,
