Hi,

We've a Warning "23190 slow ops, oldest one blocked for 59390 sec, osd.28 has slow ops" on the dashboard. But there is no osd.28 on the system.

There was one, but we've deleted it. Now it shown as "Down" with this warning. If I click on the "Down" button, it normally shows the OSDs that are down. But the list is empty.

How can we properly remove this osd.28?

Thank you

It was deleted from ui. We've removed the disk and then deleted it from the ui.

ceph osd tree is not showing it, but ceph osd dump:
