It requires an OSD restart, unfortunately. Josh On Fri, May 24, 2024 at 11:03 AM Mazzystr <mazzystr@gmail.com> wrote:
Is that a setting that can be applied runtime or does it req osd restart?

Hey Chris,
A number of users have been reporting issues with recovery on Reef with mClock. Most folks have had success reverting to osd_op_queue=wpq. AIUI 18.2.3 should have some mClock improvements but I haven't looked at the list myself yet.

Hi all, Goodness I'd say it's been at least 3 major releases since I had to do a recovery. I have disks with 60-75,000 power_on_hours. I just updated
from
Octopus to Reef last month and I'm hit with 3 disk failures and the mclock ugliness. My recovery is moving at a wondrous 21 mb/sec after some serious hacking. It started out at 9 mb/sec.
My hosts are showing minimal cpu use. normal mem use. 0-6% disk business. Load is minimal so processes aren't blocked by disk io.
I tried the changing all the sleeps and recovery_max and setting osd_mclock_profile high_recovery_ops to no change in performance.
Does anyone have any suggestions to improve performance?
Thanks, /Chris C _______________________________________________ ceph-users mailing list -- ceph-users@ceph.io To unsubscribe send an email to ceph-users-leave@ceph.io
