Devices The underlying devices that make up the logical volume:
the physical volumes, logical volumes, and start physical
extents and logical extents
Attr The status of the logical volume. The logical volume

invalid (S)uspended snapshot, mapped (d)evice present
without tables, mapped device present with (i)nactive

Bit 6: device (o)pen
KMaj Actual major device number of the logical volume (-1 if

KMIN Actual minor device number of the logical volume (-1 if
inactive)
Maj The persistent major device number of the logical volume
(-1 if not specified)
Min The persistent minor device number of the logical volume
(-1 if not specified)
LV The name of the logical volume
LSize The size of the logical volume
