Ceph » rgw

Hello,

I have stumbled upon an inconsistency regarding the use of client.radosgw.* and client.rgw.* as the name of the radosgw daemons. In particular, I am having issues adding keyrings for client.radosgw.* using the bootstrap-rgw profile, since it only allows me to update/create client.rgw.* nodes.

See the imposed limitations of the profile in MonCap.cc:
https://github.com/ceph/ceph/blob/master/src/mon/MonCap.cc#L172

This is to be contrasted with most of the documentation; a quick git grep in the docs/ gives an indication (note: indication; the git grep is quite a rough tool in this case):

ceph/doc $ git grep 'client\.rgw\.' | wc -l
10
ceph/doc $ git grep 'client\.radosgw\.' | wc -l
75

It is also colliding with the default init scripts, which assumes that all radosgw:s are named client.radosgw.*:
https://github.com/ceph/ceph/blob/master/src/init-radosgw#L44-66
..which means that nodes added using the bootstrap-rgw key cannot be started using the shipped init script.

To solve this issue, I have two suggestions:

• For currently released versions: Update the above init script to search for client.rgw.* in addition to client.radosgw.*; update MonCap.cc to allow changes to client.radosgw.* in addition to client.rgw.*
• For some future version: Refactor all instances of client.rgw in the source and documentation to use client.radosgw instead.

I can implement these solutions and create a/some pull request(s) for any branches that you feel applicable for each solution if you wish, but will await any discussions before doing so.

Thanks,
/Jonas
