Mount/unmount a ``cfuse`` client.
|
|
|
|
The config is optional and defaults to mounting on all clients. If
|
|
a config is given, it is expected to be a list of clients to do
|
|
this operation on. This lets you e.g. set up one client with
|
|
``cfuse`` and another with ``kclient``.
|
|
|
|
Example that mounts all clients::
|
|
|
|
tasks:
|
|
- ceph:
|
|
- cfuse:
|
|
- interactive:
|
|
|
|
Example that uses both ``kclient` and ``cfuse``::
|
|
|
|
tasks:
|
|
- ceph:
|
|
- cfuse: [client.0]
|

- kclient: [client.1]
