I managed to find a solution:
1. Determine which OSD failed after removing the disk (the status shows that the failure occurred with osd.2):
ceph osd tree
2. On the proxmox2 host, get a list of used LVM volumes for OSD (find the used device name for osd.2):
ceph-volume lvm list
3...
Hello.
If I accidentally remove the drive from the server and then plug it back in, what is the procedure for osd to work correctly without rebooting the server?
