Description

Currently, cephadm does not support controlled upgrades/staggered upgrade / finer-grained commands.

Ability to upgrade one daemon, one host, one rack, ...
one type of daemon, rather than one monolithic process. This will make managing an upgrade in a large cluster much easier.

For example in ceph-ansible we have --limit and --tag options for controlled upgrade where we can upgrade each type of daemon at once and one host/rack at a time.

Adam, this appears to not be in v16.2.10:
