Hello,

I've run into the same things other people and myself ran into before.

It does better because it is a fair share queue and doesn't let recovery
ops take priority over client ops at any point for any time. It allows
clients to have a much more predictable latency to the storage.

on Luminous.
I presume a flag somewhere wasn't unset whilst the autoscaling was reducing
PGs? I wasted a lot of time this last week after having enabled
pg_autoscale_mode on pools in a cluster. I had to manually

Hi list,
Yesterday afternoon we experienced a compute node outage in our
OpenStack (obviously Ceph backed) cluster.
We tried to (re)start compute instances again as fast as possible,
resulting in some KVM/RBD clients getting blacklisted. The problem was
spotted very quickly so we could remove the
