Hi Eugen,
Yes, sure, no problem to share it. I attach it to this email (as it may

Good morning,
I would be grateful if anybody could shed some light on this, I can't

We noticed extremely slow performance when remapping is necessary. We didn't do
anything special other than assigning the correct device_class (to ssd). When
checking ceph status, we notice the number of objects recovering is around
17-25 (with watch -n 1 -c ceph status).
How can we increase

Hello,
This is a known issue in quincy which uses mClock scheduler. There is a fix
for this which should be
available in 17.2.6+ releases.
You can confirm the active scheduler type on any osd using:
ceph config show osd.0 osd_op_queue
If the active scheduler is 'mclock_scheduler', you can try
Hi,
Might be a dumb question …
I'm wondering how I can set those config variables in some but not all RGW
processes?
I'm on a cephadm 17.2.6. On 3 nodes I have RGWs. The ones on 8080 are behind
haproxy for users. the ones one 8081 I'd like for sync only.
# ceph orch ps | grep rgw
rgw.max.maxvm
Hi,
The config shows "mclock_scheduler" and I already switched to the
high_recovery_ops, this does increase the recovery ops, but only a little.
You mention there is a fix in 17.2.6+, but we're running on 17.2.6 (this
cluster is created on this version). Any more ideas?
Best regards

Just to add:
high_client_ops: around 8-13 objects per second
high_recovery_ops: around 17-25 objects per second
Both observed with "watch - n 1 - c ceph status"

Hi Sake,
We are experiencing the same. I set “osd_mclock_cost_per_byte_usec_hdd” to 0.1
(default is 2.6) and get about 15 times backfill speed, without significant
affect client IO. This parameter seems calculated wrongly, from the description
5e-3 should be a reasonable value for HDD (correspo
Thanks for the input! Changing this value we indeed increased the recovery
speed from 20 object per second to 500!
Now something strange:
1. We needed to change the class for our drives manually to ssd.
2. The setting "osd_mclock_max_capacity_iops_ssd" was set to 0. With osd bench
descriped in t
Did an extra test with shutting down an osd host and force a recovery. Only
using the iops setting I got 500 objects a second, but using also the
bytes_per_usec setting, I got 1200 objects a second!
Maybe there should also be an investigation about this performance issue.
Best regards
