Re: RDB

[Gary Bruce <garyofscotland@xxxxxxxxx>]

Hi All,

A bit of an update... I should have run the command from my-cluster directory. I am now receiving this error:

alphaceph@cephadmin1:~/ceph-deploy/my-cluster$ rbd create fooimage --size 1024 --pool barpool -m cephserver1.zion.bt.co.uk -k /etc/ceph/ceph.client.admin.keyring
2013-06-17 08:55:14.751204 7f1b28950780 -1 monclient(hunting): ERROR: missing keyring, cannot use cephx for authentication
2013-06-17 08:55:14.751212 7f1b28950780  0 librados: client.admin initialization error (2) No such file or directory
rbd: couldn't connect to the cluster!

More FYI....
alphaceph@cephadmin1:~/ceph-deploy/my-cluster$ more ceph.client.admin.keyring

[client.admin]
        key = AQCp5rNRkBLCHRAAOqfY/24mkYCQZ7sNy/8BDA==

alphaceph@cephadmin1:~/ceph-deploy/my-cluster$ more ceph.conf
[global]
fsid = 5e29db66-a1f1-4220-aa19-ab82020adc78
mon initial members = cephserver1
mon host = 10.255.40.22
auth supported = cephx
osd journal size = 1024
filestore xattr use omap = true
osd crush chooseleaf type = 0

Thanks

Gary

Hi All,

I finally got around to progressing with this but immediately got this message. Any thoughts?

Gary,

I've added that instruction to the docs. It should be up shortly. Let
me know if you have other feedback for the docs.
