14 pvck checks physical volume LVM metadata for consistency.
16 See \fBlvm\fP for common options.
18 .BR \-\-labelsector " sector"
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 MB. 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):
27 .BI "pvck --labelsector 204800 /dev/sda"
29 Note that a script can be used with \fB--labelsector\fP to automate the
30 process of finding LVM labels.
