Good afternoon!

I have a small Ceph-cluster running with Proxmox, and after an update
on one of the nodes and a reboot. So far so good.
But after a couple of hours, I saw this:

root@pve2:~# ceph health detail

  io:

I am not really concerned over lost data, since I am 99% sure it
belonged to a faulty prometheus server anyway.
The question is, how can I remove the warnings without affecting the
other objects?

Thankful for any pointers!
