Listmates,

After running out of room on my / partition on my Archlinux install and recovering by adding a couple of additional partitions, I put together a little howto in the wiki concerning the process in case anyone else finds themselves in the same situation:

http://wiki.archlinux.org/index.php/Add_New_Partitions_To_Existing_System

As always, writing it up for the wiki took a whole lot longer than fixing the original problem, but now it's done. Look it over, add to it, find all my typos, etc.. Hopefully it will be useful.

Hi David,

Another option would be LVM. With it you could easily grow your (logical) partitions and even adding another disk if needed.

Thanks Armando. One of these days I will have to learn LVM. That's one part of the filesystem schemes I haven't gotten to yet. -- David C. Rankin, J.D.,P.E. Rankin Law Firm, PLLC 510 Ochiltree Street Nacogdoches, Texas 75961 Telephone: (936) 715-9333 Facsimile: (936) 715-9339 www.rankinlawfirm.com

Highly recommended that you adopt LVM into your bag of tricks. It's pretty brilliant!

Here's some basic intro pointers if you want to get started:

You can move on to the full HOWTO after that for all the nitty gritty details:

Excellent DR, Thank you again for the great links and pointers in the right direction. There is so much to Linux going on, it's hard to know which tool to collect next ;-) -- David C.

That can be a problem, depending how your LVM is configured. If you have a logical volume that spans multiple disk drives, then the file system on that volume can get corrupted and/or unreadable/unwriteable. So it's generally a bad idea to do that. Your options around this are either: * make every physical disk be its own volume group, thereby ensuring that no logical volume can span more than one disk. (I do this on my machines, and this works fine for my personal needs, where I only need relatively small amounts of storage. But this wouldn't work for large-scale situations such as where you're trying to create huge virtual disks with multiple terabytes of storage.) * use a raid array as the physical volume underlying a volume group. The redundancy of the raid array would guarantee that the physical storage would still be accessible even if one of the disk drives in the array died. People who use LVM in hard-core, large-scale operations usually go this route. HTH, DR

It dies
