I got my first hands on experience with a G1 today, and I have to say that I like it a lot. I actually wrote this post on the phone. Hopefully by the time my contract with verizon expires I will have enough money to buy my own.

Ubuntu Installation Issues: RAID

November 14th, 2008
Comments Off

I set up the partitions on my hard drives the way I wanted. I have dual 500GB sata drives that I wanted to put in a RAID 0 with 2 partitions. 495GB each for the OS and then the remaining space for swap. When I was done configuring everything and wrote the changes to disk, I got the following error:

“The kernel was unable to re-read the partition table on /dev/md0 (Invalid argument). This means Linux won’t know anything about the modifications you made until you reboot. You should reboot your computer before doing anything with /dev/md0.”

This was followed by an identical error for /dev/md1. I’m still not sure of exactly what caused the error, but the quick fix I used was to hit the ESC key after the errors take place, wait for the menu to show up (the computer wants to install the base system first), then without changing anything else, set up the RAID partition that you are installing the OS, and don’t modify the swap partition or anything else like that. When I did this I still got the error for /dev/md1, but I did not get one for /dev/md0, which is what I am installing the OS to.

Asterisk Up and Running

I’ve had some free time the past few days, so I started up one of my old projects: building a PBX. It turns out that my project server was several versions out of date, so I had to download the latest Trixbox ISO. Trixbox is an open source operating system and software stack that makes Asterisk very easy to manage. I pulled out an older model FXS 4 port module that was made by Audiocodes and spent several hours trying to get it to work. After much frustration I now have a working Asterisk system. The next step is to connect it into my existing home wiring, but that is proving difficult. All of the wiring in this house (including phone lines) seems to have been an after thought, as nothing was connected or routed properly. Go figure. It’ll take me a while to figure out where everything goes.
