Hi Wido, thanks for answers - I have mons and OSD on each host...
server1: mon + 2 OSDs, same for server2 and server3.
Any Proposed upgrade path, or just start with 1 server and move along to
others ?
Upgrade the packages, but don't restart the daemons yet, then:
1. Restart the mon leader
2. Restart the two other mons
3. Restart all the OSDs one by one
I suggest that you wait for the cluster to become fully healthy again
before restarting the next OSD.
Wido
Thanks again.

Hi,
I have existing CEPH cluster of 3 nodes, versions 0.72.2
I'm in a process of installing CEPH on 4th node, but now CEPH
version is
0.80.1
Will this make problems running mixed CEPH versions ?
No, but the recommendation is not to have this running for a very
long period. Try to upgrade all nodes to the same version within a
reasonable amount of time.
I intend to upgrade CEPH on exsiting 3 nodes anyway ?
Recommended steps ?
Always upgrade the monitors first! Then to the OSDs one by one.
Thanks
