pvck checks physical volume LVM metadata for consistency.
See lvm for common options.
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.
