Just a follow up 24h later, and the mgr's seem to be far more stable, and have
had no issues or weirdness after disabling the balancer module.
Which isn't great, because the balancer plays an important role, but after
fighting distribution for a few weeks and getting it 'good enough' I'm taking
the stability.
Just wanted to follow up with another 2ยข.
What is your balancer settings (`ceph config-key ls`)? Your mgr running
in virtual environment or on bare metal?
How much pools you have? Please also paste `ceph osd tree` & `ceph osd
df tree`.
Measure time of balancer plan creation: `time ceph balancer optimize new`.
