I’ve been using an USB disk attached to an Airport Extreme lately, and for some any reasons I go, after being able to use it as a Time Machine backup disk, I received the message

Time Machine could not complete the backup. 
The backup disk image"/Volume/.....sparsebundle " is already in use.

Searching for a solution on the web, most of the time this issue is said to be fixed by deleting the sparsebundle file and reinitiating the backup. You’re probably thinking that this is not exactly what can be “acceptable“.

Hopefully, and thanks to a cnet review, I figure out that the following steps can fix the issue, and keep your previous backups safe:

• Access the Airport Extreme using the AirPort Utility
• Go to Manual Setup

• Go to Disks

  
• Click on Disconnect All Users…
• At this stage, unplug or turn the external HD off, the plug it back or turn it on

Everything should be back to normal

The following is a documentation that can be usefull for those who want to access their Unix data from a Windows workstation (Why don’t you use Linux/Mac OS workstations?)

Let start with this:

• The ADS domain name is the same as the DNS name: nulldom.com
• The ADS Kerberos realm is the same as the DNS domain name (written in capitals): NULLDOM.COM

In the following step-by-step the server that will join the domain is named sol10svr.nulldom.com, and is installed with Solaris 10u8 (running on x86).

Here is a little quick and dirty script which allows to choose the OS that will be booted from the command line.
The script has been written to work with RedHat Linux (Some updates will be required to match the use of GRUB2.

The idea of this script is simply to create a grub.conf file from grub.conf files found on the different disks on the server (Ooops, I’ve forgotten to say this: One and only one OS is installed per disk - for now ) and set the default entry to the one chosen by the user.

Find the script here: rem_reboot.pl
Testing the user id has been added to exit the script before actually running it if not run as root

Configuring a shared printer with CUPS is something quite easy. Nevertheless, it appears that I haven’t been able to print from a Mac OS X client (I haven’t tried from any other client OS).
Trying to print a document from the client has lead to the following type of error message:

E [29/Oct/2009:22:35:23 +0100] Request from "client ip address" using invalid Host: field "servername.domain"

To fix this, add the following to the /etc/cups/cupsd.conf file:

ServerAlias *

and restart CUPS:

root@servername~# /etc/init.d/cups restart
