Client not finding keyring

[RJ Nowling <rnowling@xxxxxxxxxx>]

Hi all,

I'm trying to set up a Ceph cluster with an S3 gateway using the ceph-ansible playbooks.  I'm running into an issue where the radosgw-admin client can't find the keyring.  The path to the keyring is listed in the ceph.conf file.  I confirmed with strace that the client opens the conf file but doesn't open the path given in the conf file -- only the default keyring paths.

Here's the output:

[vagrant@ceph-rgw0 ~]$ sudo radosgw-admin usage show

2016-06-01 13:36:17.294935 7fe45ac80a40 -1 auth: unable to find a keyring on /etc/ceph/ceph.client.admin.keyring,/etc/ceph/ceph.keyring,/etc/ceph/keyring,/etc/ceph/keyring.bin: (2) No such file or directory

2016-06-01 13:36:17.300732 7fe45ac80a40 -1 monclient(hunting): authenticate NOTE: no keyring found; disabled cephx authentication

2016-06-01 13:36:17.300737 7fe45ac80a40  0 librados: client.admin authentication error (95) Operation not supported

couldn't init storage provider

Here's the relevant part of the config file:

[client.radosgw.rgw0]

host = ceph-rgw0

keyring = /var/lib/ceph/radosgw/ceph-rgw.ceph-rgw0/keyring

rgw socket path = /tmp/radosgw-ceph-rgw0.sock

log file = /var/log/ceph/ceph-rgw-ceph-rgw0.log

rgw data = "">

rgw frontends = civetweb port=10.0.2.15:8080 num_threads=50

When I copy the keyring to /etc/ceph/keyring, the keyring is found but I get a different error:

[vagrant@ceph-rgw0 ~]$ sudo radosgw-admin usage show

2016-06-01 21:07:22.677525 7f62f2e38a40  0 librados: client.admin authentication error (22) Invalid argument

couldn't init storage provider

Any insights would be greatly appreciated!

Thanks!

RJ
