I'm getting the following error using ceph-deploy to setup a cluster. It's Centos6.6 and I'm using Hammer and the latest ceph-deploy. It looks like setgroup wasn't an option in Hammer, but ceph-deploy adds it. Is there a trick or older version of ceph-deploy I should try? - Noah [cn67][INFO ] Running command: sudo ceph-mon --cluster ceph --mkfs -i cn67 --keyring /var/lib/ceph/tmp/ceph-cn67.mon.keyring --setgroup 10 [cn67][WARNIN] too many arguments: [--setgroup,10] [cn67][DEBUG ] --conf/-c FILE read configuration from the given configuration file [cn67][WARNIN] usage: ceph-mon -i monid [flags] [cn67][DEBUG ] --id/-i ID set ID portion of my name [cn67][WARNIN] --debug_mon n [cn67][DEBUG ] --name/-n TYPE.ID set name [cn67][WARNIN] debug monitor level (e.g. 10) [cn67][DEBUG ] --cluster NAME set cluster name (default: ceph) [cn67][WARNIN] --mkfs [cn67][DEBUG ] --version show version and quit [cn67][WARNIN] build fresh monitor fs [cn67][DEBUG ] [cn67][WARNIN] --force-sync [cn67][DEBUG ] -d run in foreground, log to stderr.
