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.
