The syntax of the :command:`host-fs-list` command is:
|
|
|
|

|
|
|
|
**<hostname\_or\_id>** is the host name or UUID of the host.
|
|
|
|
#. Optionally, list details about a filesystem.
|
|

|
The syntax of the :command:`host-fs-show` command is:
|
|
|
|
.. code-block:: none
|
|
|
|
host-fs-show <hostname_or_id> <fs_name_or_uuid>
|
|
|
|
**<hostname\_or\_id>**
|
|
The host name or UUID of the host.
|
|
|
|
**<fs\_name\_or\_uuid>**
|
|
The name or UUID of the file system.
