SYNOPSIS
lvmdiskscan [-d|--debug] [-h|--help] [-l|--lvmpartitions] [-v|--verbose]
DESCRIPTION
To give an overview about online peripherals usable to LVM, lvmdiskscan scans all SCSI, (E)IDE disks, multiple, loop and network block
devices in the system and lists them on standard output with name, size and type (text/hex). The size is the real device size, not the size
stored in the VGDA (See pvcreate(8) ) for details.
OPTIONS
-d/--debug
Enables additional debugging output (if compiled with DEBUG).
-h, --help
Print a usage message on standard output and exit successfully.
-l, --lvmpartition
Gives an overview about all LVM system identified partitions only.
-v, --verbose
Gives verbose runtime information about lvmdiskscan's activities.
DIAGNOSTICS
lvmdiskscan returns an exit code of 0, if disks / multiple devices / partitions where found and > 0 for error:
1 no special files found
2 no disks / multiple devices / disk partitions found
95 driver/module not in kernel
96 invalid I/O protocol version
97 error locking logical volume manager
98 invalid lvmtab (run vgscan(8))
99 invalid command line
