Hi!
I'm planning a service window to make some network upgrades, and would like
to use the same window to upgrade our Ceph cluster from 16.2.10 to the
latest 17.2.x available on that date.
The cluster is a fairly simple 6-node setup with a mix of NVME (WAL/DB) and
HDD (block) drives, several replicated pools and 1 testing EC pool. Are
there any known issues or caveats I should consider to better prepare for
such an upgrade?
I would very much appreciate any advice!
Read the release notes (also from previous quincy releases, especially
the "notable changes"), and the upgrade procedure to quincy to the
letter [1].
