You mention here the "recommended (and most tested) order" which
order is that?
Using cephadm with containers wouldn't the orchestrator command
below take care of everything without having me to worry about any
upgraded order/path?
Yes, the orchestrator does that for you, but it can't hurt to
understand what the order is. Before cephadm managed the update order
it was/is like this:
1. Ceph Monitors/Ceph Managers
2. Ceph OSDs
3. Metadata Servers
4. Gateways
Zitat von mabi <mabi@xxxxxxxxxxxxx>:
Thanks to both of you for your answers. So I understand that the
best practice would be to keep all nodes on the same Ceph version
number.
