Hey everyone,
I've been reading a lot about the upgrade path from 4.4 to 5.1 and I just wanted to clarify that I understand everything I've read.
My current setup is a 3 node cluster running Ceph Jewel. Ideally, I'd like to be able to do the upgrade with zero downtime, and I believe it should be possible based on what I've read.
The process would look like this:
- Upgrade Ceph from Jewel to Luminous. I'm hoping I can do this and leave everything else at its current version until I'm happy that everything is fine. I also believe I can do this with 0 downtime?
- Migrate all VM's off of one node to the other two
- Upgrade Proxmox on the now empty node to version 5.1
- Test everything
- Migrate all VM's from one of the other nodes to the now 5.1 version of Proxmox
- Upgrade the second node
- Repeat for the final node
Does anybody see any pitfalls or holes in my logic?
Cheers,
Eric
