PGs are not perfectly balanced per OSD, but I think that's expected/OK
due to setting crush_compat_metrics to bytes? Though realizing as I
type this that what I really want is equal percent-used, which may not
be possible given the slight variation in disk size (see below) in my
cluster?

Why did you choose compat mode? Don't you want to try another one instead?

End of message. Next message?
what's your 'ceph osd df tree' outputs？does the osd have the expected PGs?

95% of usage is CephFS. Remaining is split between RGW and RBD.

I think the mimic balancer doesn't include omap data when trying to
balance the cluster. (Because it doesn't get usable omap stats from
the cluster anyway; in Nautilus I think it does.) Are you using RGW or
CephFS?

Hi everyone,
On my 13.2.5 cluster, I recently enabled the ceph balancer module in
crush-compat mode. A couple manual 'eval' and 'execute' runs showed
the score improving, so I set the following and enabled the auto
balancer.
mgr/balancer/crush_compat_metrics:bytes # from
