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
