Hi, That's exactly what I meant. I did try to activate but it fails and the problem is due to bluestore label gone after reboot, which in the end caused the activation fail and /var/lib/ceph/osd/ceph-$osd empty Upgrading from Pacific to Quincy solved the problem for me.

However, I found that after rebooting a host, some OSDs in the host will have empty /var/lib/ceph/osd/ceph-$osd And I am not able to recover from there. Am I missing any steps? I am running Oracle Linux 8.7, pacific release, ol8.
