An LVM Volume Group

XXX Maybe this should inherit from StorageDevice instead of
    DMDevice since there's no actual device.

Method Details [hide private]

__init__(self, name, parents, size=None, free=None, peSize=None, peCount=None, peFree=None, pvCount=None, uuid=None, exists=None, sysfsPath='')
(Constructor)

source code  
Create a LVMVolumeGroupDevice instance.

Arguments:

    name -- the device name (generally a device node's basename)
    parents -- a list of physical volumes (StorageDevice)

Keyword Arguments:

    peSize -- physical extent size (in MB)
    exists -- indicates whether this is an existing device
    sysfsPath -- sysfs device path

    For existing VG's only:

        size -- the VG's size (in MB)
        free -- amount of free space in the VG
        peFree -- number of free extents
        peCount -- total number of extents
        pvCount -- number of PVs in this VG
        uuid -- the VG's UUID
