pvdata − shows debugging information about a physical volume
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...]
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.
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
