    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.
