Thank you Dan! I will definitely disable autoscaler on the rest of our pools. I
can't get the PG numbers today, but I will try to get them tomorrow. We

Thank you,

Thanks Matt! I didn't know about nobackfill and norebalance! That could be a
good stop gap, as long as there's no issue having it set for weeks. We estimate
our legacy bluestore cleanup to take about 3-4 weeks.
You are correct, I don't want to cancel it we just need to catch up on other

Hi Ray,
Disabling the autoscaler on all pools is probably a good idea. At
least until https://tracker.ceph.com/issues/53729 is fixed. (You are
likely not susceptible to that -- but better safe than sorry).
To pause the ongoing PG merges, you can indeed set the pg_num to the
current value. This wi
It sounds like this is from a PG merge, so I'm going to _guess_ that you
don't want to straight up cancel the current backfill and instead pause
it to catch your breath.
You can set `nobackfill` and/or `norebalance` which should pause the
backfill. Alternatively, use `ceph config set osd.* os

Hi Joao,
I have seen something like this in Luminous after increasing the size from
1 to 3, almost looks like an extra copy is being kept. I was never able to
resolve this without recreating the pool.

Hi Iban,
Most of these options fall under the osd section. You can get
descriptions of what they do here:

The journal settings are for the old filestore backend and aren't
relevant unless you are using it. Still, you can

Thank you much for the great writeup! This definitely has been a major

Thanks for the report. 9 hours fsck is the longest I've heard about
yet -- and on NVMe, that's quite surprising!
Which firmware are you running on those Samsung's? For a different
