It can be done.
However, with the node hosting OSDs already has enough work to do and you will
run into performance issues.
It's been, and can be done, but you are better off to not do so.

Subject: [ceph-users] Mapping RBD On Ceph Cluster Node
To: <ceph-us...@ceph.com>
This is more of a "why" than a "can I/should I" question.
The Ceph block device quickstart says (if I interpret it correctly) not to use
a physical machine as both a Ceph RBD client and a node for hosting OSDs or
other Ceph services.
Is this interpretation correct? If so, what is the reasoning? If not, what is
it actually saying?
Thanks in advance.
