This thing comes with a 40G HDD which was working up to this point, but now it is filled up. What is the best way to upgrade the HD in your opinion
There is a much easier way than where you are heading. I have done it a few times and it works like a treat. You are going to have to search the wiki as previously suggested for exact details as I dont remember the steps exactly nor do I have the link on hand - maybe someone else does.
Basically you add the drive to the existing machine, at the console login as admin, create a mirror with the new drive and mirror it.
The new drive will be indentical to the existing drive, including partition sizes.
Remove original drive and boot from the new drive.
You then need to log in at the console as root and run several commands at the prompt line to resize the partition.
It is all fairly painless and your original drive remains totally intact should something go amiss.
Search the wiki and the forums under lvm, resize and the article will come up.
Hope this helps
