|

See \fBlvm\fP(8) for common options.

.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.
