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]] Physi-
       calVolumePath [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 giv-
              ing 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
