NAME
       pvck - check physical volume metadata

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

DESCRIPTION
       pvck checks physical volume LVM metadata for consistency.

OPTIONS
       See lvm(8) 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 MiB.  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.
