They should be That's exactly the question... My cluster are : 5 server with «small» ssd for service (each got 2 ssd no currently used) 6 server with «huge» HDD for data (each got 2 ssd no currently used) so for my cephfs metadata I can put them on my 5 servers for services (but that's mean the mds running on those 5 servers) or should I use the ssd on the 6 server who hold the OSD for data Thanks.
