def discoverVolumes(volumeName, list):
"""
This method helps to discover volumes list and volume info
Parameters
----------
list: Flag used for getting volume info. If the flag is 'True' then the
method will return only list of volume names with volume Type and doesn't
include the brick details. . If list is 'False' then returns the volume
details with brick information.
volumeName: Fetch information only for the given volume.
Note: glustercli.volumeInfo(volName) command accept a volumeName. But if
the volume name is not passed then it returns details about all the volumes
in the cluster.
Returns
---------
Returns volume details in the following dictionary format
{
'vol-name' : {vol-details}
'vol-name' : {vol-details}
'vol-name' : {vol-details}
...
}
