Hi,
> Is this the way to go? I would like as little performance degradation
while rebalancing as possible.
Please advice if I need to take in account certain preparations.
Set these in your ceph.conf beforehand:
osd recovery op priority = 1
osd max backfills = 1
I would allso suggest creating a new crush rule, instead of modifying your
existing one.
This enables you to change the rule on a per pool basis:
ceph osd pool set <poolname> crush_rulenum <number>
Then start with your smallest pool, and see how it goes.
