PVCK

NAME

pvck − check physical volume metadata

SYNOPSIS

pvck [−d|−−debug] [−h|−−help] [−v|−−verbose] [−−labelsector sector] PhysicalVolume [PhysicalVolume...]

DESCRIPTION

pvck checks physical volume LVM metadata for consistency.

OPTIONS

See lvm(8) for common options.
−−labelsector
sector

By default, 4 sectors of PhysicalVolume 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 −−labelsector parameter with a value of 204800 (100 * 1024 * 1024 / 512 = 204800):

pvck −−labelsector 204800 /dev/sda

Note that a script can be used with −−labelsector to automate the process of finding LVM labels.
