Ceph 19.2.1 2 OSD(s) experiencing slow operations in BlueStore

[SteveITS]

Just to ask are we sure this is a problem? They added a warning for slowness but has something actually gotten slower or are they just alerting on the same behavior now?

A still have no alerts for 5 days ...

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

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

wuwzy: You were right, from time to time, osd is slow... clean itself ... come again ... , etc ...

The new hotfix will be coming.

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.

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