Wido,
one final question:
since I compiled libvirt1.2.3 usinfg ceph-devel 0.72 - do I need to
recompile libvirt again now with ceph-devel 0.80 ?
Perhaps not smart question, but need to make sure I don't screw something...
No, no need to. The librados API didn't change in case you are using RBD
storage pool support.
Otherwise it just talks to Qemu and that talks to librbd/librados.
Wido
Thanks for your time,
Andrija

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
