I recently reinstalled one of the boxes here, Lorien, from scratch. It was a brand new SATA disk and I used the Debian Lenny beta 2 installer. I'd never tried LVM before, I'd always used \"normal\" partitioning, but for some reason I figured I'd give this a shot. It all worked ok, but it left one problem. The amount of space Debian allocated to the root partition was pitifully small (less than 300 megabytes), and I hit a snag when a kernel upgrade came through, and wanted to install lots of stuff in that partition. So, first of all a warning, the guided partitioning is, and always has been in my opinion, not too optimal in the way it picks spaces for partitions. Secondly, here is how I fixed it, which is a slight pain since you can't have the root partition mounted.<\/p>\n
Since I was going to have to resize my root partition, I used my Debian install CD again, but this time in rescue<\/em> mode (just type rescue at the prompt).<\/p>\n Then you can get a terminal up. I had inadvertently mounted my root partition as \/target, so I began by unmounting it.<\/p>\n Next we need to reduce a partition. I chose to resize my home partition, original 200G to 199G, since I reckoned an extra gigabyte would be more than enough on the root partition.<\/p>\n Finally, increase the size of the root partition.<\/p>\n I recently reinstalled one of the boxes here, Lorien, from scratch.
