Hi Frank, I don't have an operational workaround, the patch https://github.com/ceph/ceph/pull/46911/commits/f43f596aac97200a70db7a70a230... is simple and can be applied cleanly. Yes, restarting the OSD will clear pool entries, you can restart it when the bluestore_onode items are very low (e.g less than 10) if it really helps, but I think you'll need to tune and monitor the performance until you can get a number that is most suitable for your cluster. But it can't help with the crash, since in general, the crash itself is basically a restart. Regards, Dongdong On Tue, Jan 10, 2023 at 8:21 PM Serkan Çoban <cobanserkan@gmail.com> wrote:
Slot 19 is inside the chassis? Do you check chassis temperature? I sometimes have more failure rate in chassis HDDs than in front of the chassis. In our case it was related to the temperature difference.

Following up on my previous post, we have identical OSD hosts. The very
strange observation now is, that all outlier OSDs are in exactly the same disk slot on these hosts. We have 5 problematic OSDs and they are all in slot 19 on 5 different hosts. This is an extremely strange and unlikely co-incidence.
Are there any specific conditions for this problem to be present or
amplified that could have to do with hardware?
