NAME

       lvscan - scan (all disks) for logical volumes

SYNOPSIS

       lvscan [-b|--blockdevice] [-d|--debug] [-D|--disk] [-h|--help] [-v|--verbose]

DESCRIPTION

       lvscan scans all known volume groups or all supported LVM block devices in the system for defined logical volumes.

   OPTIONS
       -b, --blockdevice
	      Adds the device major and minor numbers to the display of each logical volume.

       -d, --debug
	      Enables additional debugging output (if compiled with DEBUG).

       -D, --disk
	      Scan for logical volumes on disk(s) instead of getting the information from the kernel.

       -h, --help
	      Print a usage message on standard output and exit successfully.

       -v, --verbose
	      Gives verbose runtime information about lvscan's activities.

       --version
	      Prints version number of tool and exits sucessfully.

DIAGNOSTICS

       lvscan returns an exit code of 0 for success and > 0 for error:

       1  no volume groups found
       2  invalid volume group name
       3  error getting VGDA from kernel

       95 driver/module not in kernel
       96 invalid I/O protocol version
