Hello Robert,
My disks did not reach 100% on the last warning, they climb to 70-80%
usage. But I see rrqm / wrqm counters increasing...

Hi Robert,
Before doing anything on my prod env, I generate r/w on ceph cluster using
fio .
On my newest cluster, release 12.2.12, I did not manage to get
the (REQUEST_SLOW) warning, even if my OSD disk usage goes above 95% (fio
ran from 4 diffrent hosts)
On my prod cluster, release 12.2.9, as soo

In your case,
an update from 12.2.9 to 12.2.12 seems to have fixed the problem !

We don't use ceph-ansible. But if ceph-ansible allow you to set specific
([osd]) settings in ceph.conf I guess you can do it.
I don't know what the policy i
Hi all!
Previous week we ran into terrible situation after added 4 new nodes
into one of our clusters.
Trying to reduce pg moves we set noin flag.
Then deployed 4 new node so added 30% of OSDs with reweight=0.
After that a huge number of PGs stalled in peering or activating state -
about 20%
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?
# ceph os
I'm glad it's working, to be clear did you use wpq, or is it still the prio
queue?
