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.
