Hello Robert, I did not make any changes, so I'm still using the prio queue. Regards Le lun. 10 juin 2019 à 17:44, Robert LeBlanc a écrit : > I'm glad it's working, to be clear did you use wpq, or is it still the > prio queue? > > Sent from a mobile device, please excuse any typos. > > On Mon,

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

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... Device: rrqm/s wrqm/s r/s w/srkB/swkB/s avgrq-sz avgqu-sz await r_await w_await svctm %util sda 0.00 4.00

With the low number of OSDs, you are probably satuarting the disks. Check with `iostat -xd 2` and see what the utilization of your disks are. A lot of SSDs don't perform well with Ceph's heavy sync writes and performance is terrible. If some of your drives are 100% while others are lower
