Install Spindown in openSUSE

To install Spindown, click this 1-click installer from Packman supported on openSUSE 11.1/11.0/10.3

This should download the YMP file and automatically launch the YaST package manager to add the required Repositories and download and install Spindown and the dependencies. Click next on the Spindown installation screen and Next again on the installation proposal window. This should start adding the required repositories, download and install Spindown and its required dependencies. Click Finish when the installation completes successfully.

This should install the Spindown daemon under /etc/init.d/

Before we can start using Spindown utility, we need to quickly setup the config file /etc/spindown.conf

There are two sections where the paramters can be defined. One is [General] which holds the global configurations and the other [Disk]. The [Disk] section can be for as many choosen disk from the ones installed on your system like [disk 0] [disk 1]. Anything defined under disks overide the global configurations under General. The config file is commented very well to guide you through and the default configs under [General] are good enough. In a simple configuration on my PC, I add my only disk to the config.

To find the device ID,

linux-pa5r:/etc # ls -l /dev/disk/by-id/

Here my disk is “ata-WDC_WD2500BEVS-75UST0_WD-WXE608PV7921“. I enter the Disk config in the /etc/spindown.conf as follows accepting the default global config under [General]:

[Disk 0]
id =ata-WDC_WD2500BEVS-75UST0_WD-WXE608PV7921
spindown = 1

Here, I define the Disk ID and set Spindown = 1 to enable the spinning down of the disk when idle. That completes the config.

Start the Spindown daemon as follows:

linux-pa5r:/etc # /etc/init.d/spindown start
Starting spindownd daemon…  spindownddone.

To check the status, use the command with “status” arguement.

linux-pa5r:/etc # /etc/init.d/spindown status
name           watched        active         idle-time      spindown-time
sda            1              1              0              3600

This to me is a simple and elegant tool which serves the useful purpose of saving some energy and extending the disk life. Click here to visit the project homepage hosted at Google Code for more information and more advanced documentation.
