| .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. |
