Ceph » RADOS

The crush tools and ceph commands will make sure there is no difference between ruleset and ruleid. However, existing crushmap in which ruleset are different from ruleid will be kept as is. It may lead to misbehavior that becomes increasingly difficult to diagnose and fix as time passes and people forget the difference ever existed.

There should be a way to either transparently make the change or at least allow the admins to trigger the change if they know it won't negatively affect external tools that rely on the fact that a ruleset may be different from a rule id.
