mount: disk already mounted or mountpoint busy

Submitted by Druss on Fri, 2008-02-01 14:32

If you run into an error message along the lines of mount: /dev/sdb2 already mounted or /media/data1 busy, and the disk has not been mounted, it usually indicates that something has locked it intentionally to prevent it from being mounted. In my case, the culprit was dmraid, a RAID management tool that I am not using any more. Uninstalling the package did the trick. (Removing the array configuration from dmraid would probably have sufficed)

hth.

dmraid: Trials and tribulations

Submitted by Druss on Fri, 2008-02-01 03:15

I have a Gigabyte board with an nForce 430 chipset that supports RAID. I was hoping to use it to create a simple RAID1 mirror using two hard drives to protect my previous MP3 collection. The system in question is an updated Kubuntu Gutsy box.

Before we start, this is the first time I am playing with RAID and the information below might very well be wrong. Please feel free to correct me :)

Konversation: notify via console beeps

Submitted by Druss on Sun, 2007-12-23 03:19

Konversation is an excellent IRC client for KDE. However, it lacks a rather fundamental (IMHO) option - event notification via console/system beeps. While it has notification options to alert the user via ogg, wav and other sound formats, if one does not have external speakers / headphones, one does not get alerted. As a result, one misses important messages and thereby one gets mucho cranky.

hal-storage-fixed-mount refused uid 1000

Twice over the last couple of weeks, I've added a new drive to my Kubuntu box and run into the error hal-storage-fixed-mount refused uid 1000 when I attempted to access any existing partitions via Dolphin or Konqueror. The first time this happened was with a Windows drive with NTFS partitions and the second time with a drive from another linux box with reiserfs partitions.

VLC, MPlayer both display garbled videos

This site is fast dwindling into a Linux help site :S

Anyway, today's issue relates to a rather odd video issue I've been facing on an infrequent basis. Every now and then all video on my Gutsy box just goes out of whack. Playing any file which would have played fine 10 minutes earlier would display a screen full of garbled lines. The audio is always fine.

Mplayer: gnome_screensaver_control() error message

Submitted by Druss on Mon, 2007-11-12 12:39

If you constantly see a gnome_screensaver_control error dialog when you open Mplayer in Kubuntu, you can fix it by unchecking the "Stop XScreenSaver" option in Mplayer preferences (under the Misc tab). The preferences and other menu options can be reached by right-clicking on either the video or controls windows.

Looks like a packaging issue.
