Hi Guys,

We're currently running a Promox 4.2 cluster with Ceph Infernalis. The Ceph managers run on external hardware, not the Proxmox hosts.

We are considering upgrading to ceph Luminous for a bunch of reason. Everything looked good until I saw this on the ceph docs.

WHICH CLIENT VERSIONS SUPPORT CRUSH_TUNABLES5
  • v10.0.2 (jewel) or later
  • Linux kernel version v4.5 or later (for the file system and RBD kernel clients)

Proxmox is using the 4.4 LTS kernel. Can anyone verify that the Promxox RBD client will work with Ceph Luminous using the newer Luminous file structure.

Here's' the output of pverversion -v if it helps.

Thanks!
 
I suggest you upgrade first from Proxmox VE 4.x to latest 5.x
 
Hi Tom, is that a requirement? We run a lot of containers on each host, migrating and updating would take days, and then we'd have to go through a lot of testing with the new version.

We'll do it of course, if there are no other options.
 
Ty again Tom. I'll really push that we upgrade. But just so I know, have you or anyone tested Proxmox v 4 with Ceph version 12?

Personally I did not test Ceph 12.x with Proxmox VE 4.x, I run all my production Clusters with current versions only.
