Regarding the inactive PGs, how are your pools configured? Can you share
ceph osd pool ls detail
It could be an issue with min_size (is it also set to 3?).

Autoscale is no longer recommending a pg_num change (I have it set to
warn). Back when this happened I was still setting the ceph custer up -
incrementally moving VM's to the ceph pool and adding OSD's as space was
freed up on the old storage (lizardfs), so not an ideal setup :) for a
while the pool was in a constant state of inbalance and redistribution,
I probably should have disabled the autoscale until I finished.
Finished now:
POOL SIZE TARGET SIZE RATE RAW CAPACITY RATIO TARGET RATIO BIAS
PG_NUM NEW PG_NUM AUTOSCALE
ceph 3230G 3.0 34912G 0.2776 1.0
512 warn
