[PVE-User] Cant connect to ceph anymore

so you would drive a 12.2 (luminous) service with a 10.x (jewel) client. 
Just a thought: 

Check the "ceph features" output on your server if it allows jewel clients. 
Sample output should contain a group with a jewel attribute in the client section. 

If this is not the case, try to set: 
ceph osd set-require-min-compat-client jewel 
(which should be default for luminous, but can be removed which leads to incompability) 

Check this link for details: https://ceph.com/community/new-luminous-upgrade-complete/ 

Maybe this helps, good luck

Betreff: [PVE-User] Cant connect to ceph anymore 


I had a proxmox 4.x Server with installed ceph Jewel (10.x) via ceph-deploy. 

The ceph Cluster is standalone Not managed by proxmox. 

I could use this ceph Cluster without any issues and the vms working fine. 

Now I upgraded my ceph Cluster to 12.2.x and was still able to connect my vms via proxmox (qemu/librbd). 

The last Step was to Update the ceph Client on this proxmox node, but now i am Not able to connect to the ceph Storage anymore :*( 

Actually i cannot Update the proxmox Node to 5.x because there is a important vm Running with local Storage. 

Proxmox Show me a empty list when i want to Browse the ceph Cluster through the gui - but i dont get any error. 

Any suggestions? 

Thanks in advise
