  13 .SH DESCRIPTION
  14 pvck checks physical volume LVM metadata for consistency.
  15 .SH OPTIONS
  16 See \fBlvm\fP(8) for common options.
  17 .TP
  18 .B \-\-labelsector \fIsector
  19 By default, 4 sectors of \fBPhysicalVolume\fP are scanned for an LVM label,
  20 starting at sector 0.  This parameter allows you to specify a different
  21 starting sector for the scan and is useful for recovery situations.  For
  22 example, suppose the partition table is corrupted or lost on /dev/sda,
  23 but you suspect there was an LVM partition at approximately 100 MiB.  This
  24 area of the disk may be scanned by using the \fB\-\-labelsector\fP parameter
  25 with a value of 204800 (100 * 1024 * 1024 / 512 = 204800):

  29 Note that a script can be used with \fB\-\-labelsector\fP to automate the
  30 process of finding LVM labels.
