"lvdisplay -v /dev/vg00/lvol2" shows attributes of that logical volume
|
|
and its mapping of logical to physical extents. In case snapshot
|
|
logical volumes have been created for this original logical volume,
|
|
this command shows a list of all snapshot logical volumes and their
|
|
status (active or inactive) as well.
|
|
|
|
"lvdisplay /dev/vg00/snapshot" shows the attributes of this snapshot
|
|
logical volume and also which original logical volume
|
|
it is associated with.
