I have a Nautlius Cluster (14.2.4) where i set the Time for scrubs to run only from 23 till 6 o'clock.
But, Last Time i increase my PGs from 512 PGs (with 15 bluestore osds - 3 nodes) to 1024 PGs (with 35 OSDs - 7 nodes) and observed running deepscrubs when he finished some rebalances...
When i set no(deep-)scrub there is no scrub running, but when i unset no(deep-)scrub it starte again. Observed this when i First increase to 532 pgs as a test.
So, is scrubbing a nessesary Part when we increase the PGs which have to be run and should not or can not wait till the defined timespan for scrubbing from the admin?
Hope you can enlighten me :)
