[ceph-users] How to get ceph-volume to take pre-existing, working auth?

I'm trying to use ceph-volume to do various things. It works fine locally, for things like ceph-volume lvm zap But when I want it to do OSD level things, it is unhappy. To use a trivial example, it wants to do things like /usr/bin/ceph --cluster ceph --keyring /var/lib/ceph/bootstrap-osd/ceph.keyring osd tree -f json but then dies saying, [errno 13] RADOS permission denied (error connecting to the cluster) and if I directly run that long command myself, it indeed dies. (which is not too surprising, since /var/lib/ceph/bootstrap-osd/ceph.keyring does not exist) However, if I just run from the same command prompt, /usr/bin/ceph osd tree -f json it works fine. How can i get ceph-volume to just use the creds that are already working somewhere? -- Philip Brown| Sr. Linux System Administrator | Medata, Inc. 5 Peters Canyon Rd Suite 250 Irvine CA 92606 Office 714.918.1310| Fax 714.918.1325 pbrown(a)medata.com| www.medata.com
