Ceph: how to add a namespace to a pool

[zeuxprox]

Hi,

I would like to add a namespace to a pool, but I wasn't able to find a guide and/or a command to do that. Could someone help me, please?
I'm using a fresh installation of Proxmox 5.1.

Thank you.

Are you sure, you mean namespace or maybe the application name of a pool?

I think you mean: how to add a permission role name.
Click on Datacenter->Permissions tab.
Add your users and groups in the obvious way, then to add a role name to a user you need to click Permissions tab and then add button.

Or maybe you mean ceph pools?

Hi,

I mean namespace within a pool of ceph as described in this doc
http://docs.ceph.com/docs/master/rados/operations/user-management/

"Namespace
Objects within a pool can be associated to a namespace–a logical group of objects within the pool. A user’s access to a pool can be associated with a namespace such that reads and writes by the user take place only within the namespace. Objects written to a namespace within the pool can only be accessed by users who have access to the namespace."

"Modify User Capabilities
The ceph auth caps command allows you to specify a user and change the user’s capabilities. Setting new capabilities will overwrite current capabilities. To view current capabilities run ceph auth get USERTYPE.USERID. To add capabilities, you should also specify the existing capabilities when using the form:

ceph auth caps USERTYPE.USERID {daemon} 'allow [r|w|x|*|...] [pool={pool-name}] [namespace={namespace-name}]
[{daemon} 'allow [r|w|x|*|...] [pool={pool-name}] [namespace={namespace-name}]']' " .

The question is: how can I add/configure a name space within a pool?

Thank you very much.

Note: Only available using librados at this time

You need to write your own code to do this, taken from the same link.

I agree, proxmox disks are visible in "rbd -p poolname ls" and "rbd -p poolname info ID" . There's no namespace support in there yet.

The namespace is on rados level, so I am not quite sure if it would show on the rbd info.

So, if I understood well, at this moment is not possible to add/configure namespace within a pool...
