Maybe it's a lame question, but is anybody knows simplest procedure, for most non-disrubtive upgrade of ceph cluster with real workload on it ?? It's most important if we want semi-automate this process with some tools. Maybe there is a cookbook for this operation ?? I know that automate this is not simple, and dangerous, but even in manual upgrade it's important to know what can we expect.
