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:
1  no physical volume name on command line
95 driver/module not in kernel
96 invalid O/O protocol version
97 error locking logical volume manager
99 invalid command line
