Hi, Thanks for your suggestions There is nothing significant in the log files expect "transitioning to stray" ( see attached) Restarting the daemons does not help as , after few minutes, they are complaining again ALL my HDD based OSDs on ALL 7 hosts are complaining [image: image.png] Steven On Tue, 13 May 2025 at 03:07, Laimis Juzeliūnas < laimis.juzeliunas@oxylabs.io> wrote:
HI Steven,
This issue has been around mailing lists since the new version came out:
https://lists.ceph.io/hyperkitty/list/ceph-users@ceph.io/thread/S5XBS63NFIBJ...
This is a new warning that can be adjusted or muted if uncomfortable but its advisable to check what’s causing this. We had a few warnings once upgraded to 19.2.2 and a single OSD restart vanished them away. Haven’t seen these warnings ever since.
Best, *Laimis J.*

Hi,
After a cephadm upgrade from 18.2.2 to 18.2.7 that worked perfectly, I am noticing lots ( 42 out of 161 OSDs ) "slow operations in bluestore" errors
My cluster has all 3 types of OSDs ( NVME, SSD, HDD+ journaling)
I found some articles mentioning below setting but it did not help
Anyone else having this issue ?
Thanks Steven
