LVM / PVMOVE ? Disk Image


Hi all,

i am using Redhat 5 for backup all data using proprietry software. all backup data is on LVM

Code:
[root@backup ~]# lvdisplay
  --- Logical volume ---
  LV Name                /dev/Storage1/lv1
  VG Name                Storage1
  LV UUID                tTjGPJ-Nfce-ZKke-668j-tJw4-styr-TqbR1j
  LV Write Access        read/write
  LV Status              available
  # open                 1
  LV Size                1.36 TB
  Current LE             357699
  Segments               1
  Allocation             inherit
  Read ahead sectors     auto
  - currently set to     256
  Block device           253:1
This is single disk and having single LVM on this. i have another disk that i want to move it to DR(disaster recovery) site. so all the (backup) data on /dev/Storage1/lv1 needs to be backup on another disk

Code:
 "/dev/sdd1" is a new physical volume of "1.36 TB"
  --- NEW Physical volume ---
  PV Name               /dev/sdd1
  VG Name
  PV Size               1.36 TB
  Allocatable           NO
  PE Size (KByte)       0
  Total PE              0
  Free PE               0
  Allocated PE          0
  PV UUID               QwrRvC-opNG-GIhv-8mFv-cuUV-prjJ-gPamp6
since copy "cp" will take to much time to copy all data to another disk and CPU utilization. can i use pvmove and move the /dev/sdd1 to DR site. and retain current disk for backup ?

or any other way to image it ?

thanks.
