Downgrade is Really a passable Way - dont know why i didnt come to this conclusion by myself ^^
So i tried to Downgrade via ceph-deploy install --release Jewel <host> but didnt worked so i decide to remove and reinstal ceph again after this.
this worked but this had also removed proxmox components like proxmox-ve and qemu-server etc. Oo :*(
Luckywise this hadnt any effect to our Running VMs.. Puh..
So i tried to reinstall the removed proxmox components but this is actually Not allowed because some libaries are in use ...
I guess i had to Reboot the Server in a Controlled way and then to instal proxmox again hopefully without loosing the actually Running VMs and local Storage.
Post by Marcus HaarmannHi,
so the client is updated to luminous but kernel not (?)
Maybe you should downgrade for the moment, as jewel clients are
supported.

Post by Marcus HaarmannHi,
so you would drive a 12.2 (luminous) service with a 10.x (jewel) client.
Sorry, with
"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 :*("
I ment ive upgraded this Node to 12.2.x, too. After this i had the descriped issue.
Post by Marcus HaarmannCheck 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.
This is clean. All other Node are already luminous (but with PVE 5.x)
Post by Marcus Haarmannceph osd set-require-min-compat-client jewel
It is already On Jewel, becouse ive upgraded from Jewel but didnt set
this to luminous till all Node are Running luminous fine.
Hope you or someone Else has Another idea why i can not See my Images
through the proxmox GUI anymore - and so i can not start my appropriate
vms.

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