Re: dumpling "ceph" cli tool breaks openstack cinder

Hi,

The new version of the driver (for Havana) doesn't need the CEPH_ARGS argument, the driver now uses the librbd and librados (not the CLI anymore).

I guess a better patch will result in:

stdout, _ = self._execute('ceph', '--id', 'self.configuration.rbd_user', 'fsid')
I'll report the bug. Thanks!
However I don't know how to fix this with the new CLI.

Cheers.

 Hi,
I just noticed that in dumpling the "ceph" cli tool no longer utilises the "CEPH_ARGS" environment variable.  This is used by openstack cinder to specifiy the cephx user.   Ref: http://ceph.com/docs/next/rbd/rbd-openstack/#configure-openstack-to-use-ceph

I modifiied this line in /usr/share/pyshared/cinder/volume/driver.py

<         stdout, _ = self._execute('ceph', 'fsid')
>         stdout, _ = self._execute('ceph', '--id', 'volumes', 'fsid')

For my particular setup this seems to be sufficient as a quick workaround.  Is there a proper way to do this with the new tool?

Note: This only hit when i tried to create a volume from an image (i'm using copy on write cloning).  creating a fresh volume didnt invoke the "ceph fsid" command in the openstack script, so i guess some openstack users will not be affected.

Thanks,

Ã?ystein
