So it looks like you machine recently crashed (power failure?) and it is
restarting.

Or upgrade some part of the OS and now it'll do resync every week or so (I
think this is debian default nowadays, don't know the interval though).

it should be only once a month... and it's just a "check" -- it reads 
everything and corrects errors.

i think it's a great thing actually... way more useful than smart long 
self-tests because md can reconstruct read errors immediately -- before 
you lose redundancy in that stripe.
