Thanks for the clarification. And by raising the PG
should we also set
"no scrub" and "no deep scrub" during data movement? What is here
the
recommandation?
Yes, I would do that. We have seen that after creating more PGs those
PGs will get (deep-)scrubbed as they have never been (deep-)scrubbed
before. Only enable (deep-)scubbing after all data has been moved and
cluster is HEALTH_OK. Because it will take a long time before they are
all (deep-)scrubbed. Make sure you have a "scrub window" that is
convenient (low traffic). Quite a few PGs might get scrubbed on
different OSDs at the same time.
Reminds me for the need for a "scrub" module in the manager to handle
this stuff properly ... as soon as I have some time I'll come up with a
proposal.
