It requires an OSD restart, unfortunately.

Hey Chris,
A number of users have been reporting issues with recovery on Reef
with mClock. Most folks have had success reverting to
osd_op_queue=wpq. AIUI 18.2.3 should have some mClock improvements but
I haven't looked at the list myself yet.

We've had success using osd_async_recovery_min_cost=0 to drastically
reduce slow ops during index recovery.

I think it depends what you mean by rados objects and s3 objects here. If
you're talking about an object that was uploaded via MPU, and thus may
comprise many rados objects, I don't think there's a difference in read
behaviors based on pool type. If you're talking about reading a subset byte
range
Personally, I don't think the compaction is actually required. Reef
has compact-on-iteration enabled, which should take care of this
automatically. We see this sort of delay pretty often during PG
cleaning, at the end of a PG being cleaned, when the PG has a high
count of objects, whether or not
Hi Jaemin,
It is normal for PGs to become degraded during a host reboot, since a
copy of the data was taken offline and needs to be resynchronized
after the host comes back. Normally this is quick, as the recovery
mechanism only needs to modify those objects that have changed while
the host is
The balancer will operate on all pools unless otherwise specified.

Periodic discard was actually attempted in the past:
https://github.com/ceph/ceph/pull/20723
A proper implementation would probably need appropriate
scheduling/throttling that can be tuned so as to balance against
client I/O impact.
