LVM question
Hi all;

I have a quick question about LVM.

2.6.18-92.1.18.el5

Distributor ID: RedHatEnterpriseServer
Description: Red Hat Enterprise Linux Server release 5.3 (Tikanga)
Release: 5.3
Codename: Tikanga


I was going through /etc/lvm.conf and I am not clear with lvm meta data backup

My question is on what basis does the backup happen.

a] Is it based on any meta data changes.
b] Is it time bound

Regards
Maverick

pvck

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

NAME

       pvck - check physical volume metadata

SYNOPSIS

       pvck [-d|--debug] [-h|--help] [-v|--verbose] [--labelsector] PhysicalVolume [PhysicalVolume...]

DESCRIPTION

       pvck checks physical volume LVM metadata for consistency.

OPTIONS

       See lvm for common options.

       --labelsector sector
	      By  default, 4 sectors of PhysicalVolume are scanned for an LVM label, starting at sector 0.  This parameter allows you to specify a
	      different starting sector for the scan and is useful for recovery situations.  For example, suppose the partition table is corrupted
	      or  lost	on  /dev/sda, but you suspect there was an LVM partition at approximately 100 MB.  This area of the disk may be scanned by
	      using the --labelsector parameter with a value of 204800 (100 * 1024 * 1024 / 512 = 204800):

	      pvck --labelsector 204800 /dev/sda

	      Note that a script can be used with --labelsector to automate the process of finding LVM labels.
