Spindown 0.2 (Default branch)
Spindown is a daemon to spin down idle disks and thus save energy and give the disks a longer lifetime. It also works with USB disks and hot-swappable disks because it uses the device ID to identify the disk instead of the device name (such as hda or sdb). This means that it doesn't matter if the disk is swapped while the daemon is running. License: GNU General Public License v3 Changes:
Now you can set the spindown time for every individual disk, and reload the settings by sending a SIGHUP to spindownd.Image

lvmdiskscan

LVMDISKSCAN(8)						      System Manager's Manual						    LVMDISKSCAN(8)

NAME

       lvmdiskscan - scan for all disks / multiple devices / partitions available

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
