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.
