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:
cephfuse: "{testdir}/mnt.0"
- cifs-mount:
client.0:
share: cephfuse
