.TH PVCK 8 "LVM TOOLS #VERSION#" "Sistina Software UK" \" -*- nroff -*-
.SH NAME
pvck \- check physical volume metadata
.SH SYNOPSIS
.B pvck
.RB [ \-d | \-\-debug ]
.RB [ \-h | \-\-help ]
.RB [ \-v | \-\-verbose ]
.RB [ \-\-labelsector
.IR sector ]
.I PhysicalVolume
.RI [ PhysicalVolume ...]
.SH DESCRIPTION
pvck checks physical volume LVM metadata for consistency.
.SH OPTIONS
See \fBlvm\fP(8) for common options.
.TP
.B \-\-labelsector \fIsector
By default, 4 sectors of \fBPhysicalVolume\fP 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 MiB. This
area of the disk may be scanned by using the \fB\-\-labelsector\fP parameter
with a value of 204800 (100 * 1024 * 1024 / 512 = 204800):
.sp
.B pvck \-\-labelsector 204800 /dev/sda
.sp
Note that a script can be used with \fB\-\-labelsector\fP to automate the
process of finding LVM labels.
