Description

Right now we disallow this with _check_remove_tier(), I believe because we were worried about coordinating the switchover. The OSDs and rados clients handle this though, thanks to their force_resend_op stuff.

Yeah, we didn't think about this first time around because the focus was on cache tiers to EC pools, but it would make sense to allow adding cache tiers to replicated pools in use by cephfs.
