We would like to have two independent clusters on the same cluster node= s,=20 specially one for user home directories (called homeuser) and one for b= ackups=20 (backup). The reason is that in case the homeuser cephfs breaks (like i= t has=20 done several times in our tests), we still have independent storage of = the=20 backups without the need of seperate server nodes. So I started experimenting with the new "cluster" variable, but it does= not=20 seem to be well supported so far. mkcephfs does not even know about it = and=20 always uses "ceph" as cluster name. Setting a value for "cluster" in gl= obal=20 section of ceph.conf (homeuser.conf, backup.conf, ...) does not work, i= t is=20 not even used in the same config file, instead it has the fixed value "= ceph". My questions: 1) Has someone here ever tried such a setup? 2) Is there an official (documented) way to at least setup ceph cluster= s with=20 individual cluster names? 3) Are there plans to support cluster names in mkcephfs?
