Hi Do I need to create any mon and/or mgr in the new ceph cluster? Em seg., 18 de ago. de 2025 às 13:03, Eugen Block <eblock@nde.ag> escreveu:
Hi,
this sounds like you created a new cluster (new fsid), the OSDs still have the previous fsid configured. I'd rather recommend to follow this procedure [0] to restore the mon store utilizing OSDs rather than trying to manipulate otherwise intact OSDs to fit into the "new" cluster. That way you'll have "your" cluster back. I don't know if there are any specifics to using proxmox, though. But the mentioned procedure seems to work just fine, I've read multiple reports on this list. Luckily, I haven't had to use it myself.
Regards, Eugen

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.
