I don't think a CRUSH rule exception is currently possible, but it makes sense
to me for a feature request.

Hi,
I have a need to support a small cluster with 3 hosts and 3 replicas given
that in normal operation each replica will be placed on a separate host
but in case one host dies then its replicas could be stored on separate
osds on the 2 live hosts.
I was hoping to write a rule that in case it could only find 2 replicas on
separated nodes will emit it and do another select/emit to place the
reaming replica. Is this possible ? i could not find a way to define an if
condition or being able to determine the size of the working vector
actually returned.
Cheers /maged
