Sorry, not trying to repost or bump my thread, but I think I can restate my question here and for better clarity. I am confused about the "--cluster" argument used when "ceph-deploy mon create" invokes "ceph-mon" on the target system. I always get a failure at this point when running "ceph-deploy mon create" and this then halts the whole ceph quick start process. Here is the line where "ceph-deploy mon create" fails: [cephtest02][INFO ] Running command: ceph-mon --cluster ceph --mkfs -i cephtest02 --keyring /var/lib/ceph/tmp/ceph-cephtest02.mon.keyring Running the same command manually on the target system gives an error. As far as I can tell from the man page and the built-in help and the website (http://ceph.com/docs/next/man/8/ceph-mon/) it seems "--cluster" is not a valid argument for ceph-mon? Is this a problem in ceph-deploy? Does this work for anyone else? ceph@cephtest02:~$ sudo ceph-mon --cluster ceph --mkfs -i cephtest02 --keyring /var/lib/ceph/tmp/ceph-cephtest02.mon.keyring too many arguments: [--cluster,ceph] usage: ceph-mon -i monid [--mon-data=pathtodata] [flags] --debug_mon n debug monitor level (e.g. 10) --mkfs build fresh monitor fs --conf/-c Read configuration from the given configuration file -d Run in foreground, log to stderr. -f Run in foreground, log to usual location. --id/-i set ID portion of my name --name/-n set name (TYPE.ID) --version show version and quit --debug_ms N set message debug level (e.g. 1) ceph@cephtest02:~$ Can anyone clarify if "--cluster" is a supported argument for ceph-mon? Thanks!
