Hello gurus,

I have a requirement of backup of a vg containing a file system.
vg1 contains 3 LV each of 50G size. They are coming out from ~350G harddisk. and only 150G is being used.

Now, i want to dd this hdisk and restore to another machine. I am not sure how to go about this.

Can some one please point me how to go about this?

i am trying
Code:
dd if=/dev/vg1 of=/export/home/image1 bs=64M

but it is throwing dd read error: No such device or address

thanks in advance

VGCONVERT(8)						      System Manager's Manual						      VGCONVERT(8)

NAME
       vgconvert - convert volume group metadata format

SYNOPSIS
       vgconvert  [-d|--debug] [-h|--help] [-t|--test] [-v|--verbose] [--labelsector] [-M|--metadatatypetype] [--pvmetadatacopies#copies] [--meta-
       datasizesize] [--version] VolumeGroupName [VolumeGroupName...]

DESCRIPTION
       vgconvert converts VolumeGroupName metadata from one format to another provided that the metadata fits into the same space.

OPTIONS
       See lvm(8) and pvcreate(8) for options.

EXAMPLE
       Convert volume group vg1 from LVM1 metadata format to the new LVM2 metadata format.

       vgconvert -M2 vg1

RECOVERY
       Use pvscan(8) to see which PVs lost their metadata.  Run pvcreate(8) with the --uuid and --restorefile options on each such PV to  reformat
       it  as  it  was, using the archive file that vgconvert(8) created at the start of the procedure.  Finally run vgcfgrestore(8) with that ar-
       chive file to restore the original metadata.

SEE ALSO
       lvm(8), pvcreate(8), vgcfgrestore(8)
