My use case - from past ages /mail is block device for kvm vm. Now I
need more space for messages, but I don't want use 3x raw space for
replicas.
What is your reccomendations? Create an RBD image on an erasure coded
pools when a replicated pool tier set a cache tier?
Thanks.

W/o further data I'd be reluctant to call that a success, at least in a
general sense.
A native dovecot-ceph object interface will certainly help performance,
but of course still be somewhat limited by the network nature of things
and also a total black box compared to maildir on a FS.
Lastly, do you feel comfortable to put all your mail eggs into one
(software) storage basket?
At a million+ users I most certainly don't.
