LV without Paging Space
Hello dear friends, We have VG filevg which consists of 2 PVs when I rechecked the VG there is no Pagingspace LV.. The VG is usually Highly loaded because much reads and writes.. Is this a must to create Paging space on the specified LV?

vgimportclone
VGIMPORTCLONE(8) System Manager's Manual VGIMPORTCLONE(8)
NAME
vgimportclone - import and rename duplicated volume group (e.g. a hardware snapshot)
SYNOPSIS
vgimportclone [-n|--basevgname VolumeGroupName] [-i|--import] PhysicalVolume [PhysicalVolume...]
DESCRIPTION
vgimportclone is used to import a duplicated VG (e.g. hardware snapshot). Duplicate VG(s) and PV(s) are not able to be used until they are
made to coexist with the origin VG(s) and PV(s). vgimportclone renames the VG associated with the specified PV(s) and changes the associ-
ated VG and PV UUIDs.
OPTIONS
See lvm(8) for common options.
-n, --basevgname VolumeGroupName
By default the snapshot VG will be renamed to the original name plus a numeric suffix to avoid duplicate naming (e.g. 'test_vg'
would be renamed to 'test_vg1'). This option will override the base VG name that is used for all VG renames. If a VG already
exists with the specified name a numeric suffix will be added (like the previous example) to make it unique.
-i, --import
Import exported Volume Groups. Otherwise VGs that have been exported will not be changed (nor will their associated PVs).
ENVIRONMENT VARIABLES
LVM_BINARY
The LVM2 binary to use. Defaults to "lvm".
Examples
The origin VG "vg00" has origin PVs "/dev/sda" and "/dev/sdb" and the respective snapshot PVs are "/dev/sdc" and "/dev/sdd". To rename the
VG associated with "/dev/sdc" and "/dev/sdd" from "vg00" to "vg00_snap" (and to change associated VG and PV UUIDs) do:
vgimportclone --basevgname vg00_snap /dev/sdc /dev/sdd
