Hello Proxmox Support,
we want to safe upgrade our system to the newest version.
The challenge ist to upgrade 5 nodes at once with the smallest downtime.
We are afraid that something may go wrong.
we have over 30 Server that are all running.
we also read that there is a new (blue)storage. So...
i follow the Upgrade Path at Hammer to Jewel
now i'm stuck at:
systemctl stop ceph-mon.<MON-ID>.<UNIQUE ID>.service
At this Point i can't find the right MON-ID, i tought it's listed at /lib/systemd/system/ i'm i right?
How to verify this? At my GUI it's named mon.0 to mon.2, but the TAB...
I've upgraded ceph from Hammer to Jewel on 2 of 4 nodes in our proxmox 4.4 cluster.
At one "pve jewel node" HA-migration (to/from) and the Ceph-log (from pve-UI) faulty.
HA-migration says "HA 200 - Migrate OK" but doesn't do anything further.
From pve-UI the ceph-log for this node says...

We would like to use it as backup...
right now we are in the process of evaluating Proxmox with Ceph storage in a small cluster (6-8 hosts).
We did our test install according to the Wiki, specifically this page: https://pve.proxmox.com/wiki/Ceph_Server
However, the pveceph tool on the latest install ISO...
we have some old 3.x cluster and want to upgrade the ceph-cluster to jewel before the upgrade of the pve-cluster starts.
Has anybody running an old pve-cluster against an ceph-jewel-cluster?
Are special settings necessary?
For using proxmox 4.2 with an existing jewel cluster, from the ceph jewel release notes, you need "rbd default features = 1" in the client section of ceph.conf. but i dont see a ceph.conf anywhere. is there somewhere else this can be set?
in a test cluster of virtual machines, did proxmox 4.2...
