Alfredo, Do you know what version of ceph-deploy has this updated functionality I just updated to 1.2.7 and it does not appear to include it.

Indeed it does! `ceph-deploy osd --help` got updated recently to demonstrate how this needs to be done (an extra step is involved): For paths, first prepare and then activate: ceph-deploy osd prepare {osd-node-name}:/path/to/osd ceph-deploy osd activate {osd-node-name}:/path/to/osd > > Thanks, > > Shain > > Shain Miley | Manager of Systems and Infrastructure, Digital Media | > smiley@xxxxxxx | 202.513.3649 > > _______________________________________________ > ceph-users mailing list > ceph-users@xxxxxxxxxxxxxx > http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com > _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
