ceph config set osd bluestore_slow_ops_warn_lifetime 600 Does this line mean: I won't read, I won't listen, and you don't say anything.

This issue has been going on for months. Apparently, no single update has been able to resolve it. As of today, September 1, 2025, this remains an unresolved issue.

Usually it disappears on Monday and Tuesday, and comes back on Wednesday, Thursday, and Friday. This is positively correlated with how busy your system is.

I see that 19.2.3 has been released. I don't know when it will be available. Will it solve this problem?

The problem still exists, and it is not solved. I can only look at the error message and pray that it will not crash. Haha.

Just updated. Today's push of ceph 19.2.2 will take 2 days to verify whether this problem is solved. I hope it will be good news.

There have been several updates, but all the upgrades cannot fix this problem. It may be caused by the Linux kernel upgrade or the Ceph upgrade. I hope it can be fixed in the next update.

For now, it seems all we can do is wait.

Thank you for your attention and reply. I have used this（bdev_async_discard_threads > 1 ） and it did not solve the problem. Maybe I need to wait for a while longer.

Half a month has passed, and this problem still exists.

There have been 8 OSD errors today, and the speed has not been found to be particularly slow.

On Tuesday, the error reappeared. With 4 osds, the error should disappear on Monday after a 2-day weekend break.

My understanding is that this fault will disappear automatically on weekends when no one is using the cluster and the pressure is reduced. If it runs for a few more days and the pressure is sufficient, the fault may reappear automatically. Just wait a few more days and you will know.

Yes, usually after 1 day, new reminders will slowly appear. I just pushed a core patch and reminded that I need to restart to make the new core take effect. I just finished it, so there are currently 0 errors. I will check again tomorrow and the day after tomorrow to see if it returns to normal.
