LOGICAL VOLUMES

~~~~~~~~~~~~~~~

| lv [ [ **-a** | **\--address** ] = *ip-address* ] [ [ **-p** | **\--port** ] 

  = *port-number* ] [ [ **-f** | **\--file** ] = *input-file* ] 

  [ [ **-i** | **\--instances** ] = *instances-file* ]

Collects the information about the logical volumes of the current node.

In order to perform this task, it needs to interact with the ``lvs`` command

line tool and to connect to the ConfD daemon to fetch some configuration

information. The following parameters allow the user to specify the position

where the daemon is listening, in case it's not the default one:

-a *ip-address*, \--address=*ip-address*

  The IP address the ConfD daemon is listening on.

-p *port-number*, \--port=*port-number*

  The port the ConfD deamon is listening on.

Instead of accessing the live data on the cluster, the tool can also read data

serialized on files (mainly for testing purposes). Namely:

-f *input-file*, \--file *input-file*

  The name of the file containing a recorded output of the ``lvs`` tool.

-i *instances-file*, \--instances=*instances-file*

  The name of the file containing a JSON serialization of instances the 

  current node is primary and secondary for, listed as::

    ([Instance], [Instance])

  where the first list contains the instances the node is primary for, the 

  second list those the node is secondary for.
