Yes, and if I didn't mention it in the original thread (I usually do when
it comes to this topic), that's what I do.
As in, no randomization (I hatez it), fixed window, kick off deep scrubs
once at the opportune time on a weekend night.
And if it fits in that time window, that's need, no need for further cron
jobs.
Righty, well I'm testing a python rados api script that works out how
many (bytes worth of) pgs it should deep scrub each night to move the
distribution to be (eventually) uniform and also spread 'em to use all
the days in deep scrub interval... will post here after satisfying
myself that it is getting the maths right!
Cheers

P.s: Sage, if you are reading this...a command to alter deep scrub dates
for pgs would be real cool :-)
