Lazy Linux: 10 essential tricks for admins
Trick 1: Unmounting the unresponsive DVD drive
The newbie states that when he pushes the Eject button on the DVD drive of a server running a certain Redmond-based operating system, it will eject immediately. He then complains that, in most enterprise Linux servers, if a process is running in that directory, then the ejection won’t happen. For too long as a Linux administrator, I would reboot the machine and get my disk on the bounce if I couldn’t figure out what was running and why it wouldn’t release the DVD drive. But this is ineffective.
