Mount/unmount a cifs 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.
|
|
|

Example that starts smbd and mounts cifs on all nodes::
|
|
|
|
tasks:
|
|
- ceph:
|
|
- samba:
|
|
- cifs-mount:
|
|
- interactive:
|
|
|
|
Example that splits smbd and cifs:
|
|
|
|
tasks:
|
|
- ceph:
|
|
- samba: [samba.0]
|
|
- cifs-mount: [client.0]
|
|
- ceph-fuse: [client.1]
|
|
- interactive:
|
|
|
|
Example that specifies the share name:
|
|
|
|
tasks:
|
|
- ceph:
|
|
- ceph-fuse:
|
|
- samba:
|
|
samba.0:
