Only change it with a custom profile, no with built-in profiles, i am configuring it from ceph dashboard. osd_mclock_scheduler_client_wgt=6 -> this is my setting Vào Th 7, 13 thg 1, 2024 vào lúc 02:19 Anthony D'Atri <aad@dreamsnake.net> đã viết:

Hi Yang and Anthony,
I found the solution for this problem on a HDD disk 7200rpm
When the cluster recovers, one or multiple disk failures because slowop appears and then affects the cluster, we can change these configurations and may reduce IOPS when recovery. osd_mclock_profile=custom osd_mclock_scheduler_background_recovery_lim=0.2 osd_mclock_scheduler_background_recovery_res=0.2 osd_mclock_scheduler_client_wgt
This got cut off. What value are you using for wgt?
And how are you setting these?
With 17.2.5 I get
[rook@rook-ceph-tools-5ff8d58445-gkl5w /]$ ceph config set osd osd_mclock_scheduler_background_recovery_res 0.2 Error EINVAL: error parsing value: strict_si_cast: unit prefix not recognized
but with 17.2.6 it works.
The wording isn't clear but I suspect this is a function of https://tracker.ceph.com/issues/57533

The 2*10Gbps shared network seems to be full (1.9GB/s). Is it possible to reduce part of the workload and wait for the cluster to return to a healthy state? Tip: Erasure coding needs to collect all data blocks when recovering data, so it takes up a lot of network card bandwidth and processor resources.
