Method Details [hide private]

__init__(self, name, vgdev, size=None, uuid=None, stripes=1, logSize=0, snapshotSpace=0, format=None, exists=None, sysfsPath='', grow=None, maxsize=None, percent=None, singlePV=False)
(Constructor)

source code  
Create a LVMLogicalVolumeDevice instance.

Arguments:

    name -- the device name (generally a device node's basename)
    vgdev -- volume group (LVMVolumeGroupDevice instance)

Keyword Arguments:

    size -- the device's size (in MB)
    uuid -- the device's UUID
    stripes -- number of copies in the vg (>1 for mirrored lvs)
    logSize -- size of log volume (for mirrored lvs)
    snapshotSpace -- sum of sizes of snapshots of this lv
    sysfsPath -- sysfs device path
    format -- a DeviceFormat instance
    exists -- indicates whether this is an existing device
    singlePV -- if true, maps this lv to a single pv

    For new (non-existent) LVs only:

        grow -- whether to grow this LV
        maxsize -- maximum size for growable LV (in MB)
        percent -- percent of VG space to take
