[ceph-users] Add previously OSD to a new installation of a 3 nodes Proxmox CEPH

Hi I have 3 nodes Proxmox Cluster with CEPH, and after a crash, I have to reinstall Proxmox from scratch, along with Ceph. OSD are intact. I already did ceph-volume lvm activate --all and the OSD appears with ceph-volum lvm list and I got a folder with the name of the OSD under /var/lib/ceph/osd. However is not appear in ceph osd tree or ceph -s or even in the web gui. Is there any way to re-add this OSD to Proxmox CEPH? Thanks a lot for any help. Best Regards --- Gilbert
