NAME

pvdata - shows debugging information about a physical volume

SYNOPSIS

pvdata [-a|--all] [-d|--debug] [-h|--help] [-E|--physicalextent] [-L|--logicalvolume] [-P[P]|--physicalvolume [--physicalvolume]] [-U|--uuidlist] [-V|--volumegroup] [-v[v]|--verbose [--verbose]] PhysicalVolumePath [PhysicalVolumePath...]

DESCRIPTION

pvdata allows you to display the volume group descriptor array (VGDA) of PhysicalVolume in part or whole for debugging purposes.

OPTIONS

-a, --all
Display all structures (PE, LV, PV, UUID, VG). The same as giving the -E -L -P -U -V options.
-d, --debug
Enables additional debugging output (if compiled with DEBUG).
-E, --physicalextent
Display physical extent structures.
-h, --help
Print a usage message on standard output and exit successfully.
-L, --logicalvolume
Display logical volume structures.
-P, --physicalvolume
Display physical volume structure in pvdisplay format. If given a second time, also display the on-disk LVM metadata locations.
-U, --uuidlist
Display the volume group UUID list.
-v, --verbose
Display verbose structure information. If given a second time, verbose runtime information about pvdata's activities are also shown.
-V, --volumegroup
Display volume group structure.
--version
Display the version and exit successfully.

DIAGNOSTICS

pvdata returns an exit code of 0 for success and > 0 for error:
