Problem for restoring lvm on different disks
Hi all,

I have a server running in RH ES4, the SCSI HD are running in RAID 1.

I backup the LVM config by using 'vgcfgbackup' and then remove all the HD.
I insert another HD (same size & branch but different model) into the machine and run linux rescue to recreate the LVM.

However, I discover that the no of cylinder and sector is different from the original HD. As I use 'fdisk' to create the partition, the block size is different.

I try to use 'pvcreate --restorefile xxx --uuid xxxx' to recreate the partiton. It said that it can't as the block number is different.

How can I restore the LVM config to the new HD?

vgcfgrestore

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

NAME

       vgcfgrestore - restore volume group descriptor area

SYNOPSIS

       vgcfgrestore [-d|--debug] [-f|--file filename] [-l[l]|--list] [-h|--help] [-M|--Metadatatype1|2] [-t|--test] [-v|--verbose] VolumeGroupName

DESCRIPTION

       vgcfgrestore  allows  you  to  restore  the metadata of VolumeGroupName from a text backup file produced by vgcfgbackup.  You can specify a
       backup file with --file.  If no backup file is specified, the most recent one is used.  Use --list for a list of the available  backup  and
       archive files of VolumeGroupName.

OPTIONS

       -l | --list -- List files pertaining to VolumeGroupName
	      List  metadata  backup  and  archive  files  pertaining  to VolumeGroupName.  May be used with the -f option.  Does not restore Vol-
	      umeGroupName.

       -f | --file filename -- Name of LVM metadata backup file
	      Specifies a metadata backup or archive file to be used for restoring VolumeGroupName.  Often this file has been created with  vgcfg-
	      backup.

       See lvm for common options.

REPLACING PHYSICAL VOLUMES

       vgdisplay  --partial  --verbose will show you the UUIDs and sizes of any PVs that are no longer present.  If a PV in the VG is lost and you
       wish to substitute another of the same size, use pvcreate --restorefile filename --uuid uuid (plus additional arguments as appropriate)	to
       initialise  it with the same UUID as the missing PV.  Repeat for all other missing PVs in the VG.  Then use vgcfgrestore --file filename to
       restore the volume group's metadata.
