New Page added to wiki - Add_New_Partitions_To_Existing_System

[David C. Rankin]

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.

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:

http://www.tldp.org/HOWTO/LVM-HOWTO/benefitsoflvmsmall.html
http://www.debian-administration.org/articles/410

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

HTH,

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 ;-)

I was just wondering...
what happens if one of the drives in the lvm array goes dead?

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

Thanks, DR

I'm thinking about getting a new drive, and both raid and lvm are things I
need to have a look at.
