Ubuntu disk partitioning question
« on: January 10, 2009, 03:05:13 AM »
Point me in the right direction, plz...

I just bought a new pc (Dell mini-9 netbook) that came with Ubuntu pre-installed.  I want to look up how the hard disk is partitioned (how many partitions,how big are they, and what parts of the filesystem live on each partition).  What's the easiest way to do this?

via the command line, type df and press enter.  It will tell you all the partitions, the mount points, and usage.

The way to see all partitions on one disk is fdisk -l device. Probably the device is either /dev/sda or /dev/hda.

"sudo fdisk" or "sudo gparted" from a command prompt in a terminal window, to see partitions.

"mount" shows what's mounted where.

"df -h" gives sizes.

gparted will give prettier pictures.  If it's not installed, "sudo apt-get install gparted" will install it for you.

Please no more posts about mini-notebooks with installed linux.  I am having a difficult time not buying one for my personal machine.

You'll be pleased to know that my Aspire One appears to have died on me then. Not recognising anything bootable. Might have to start another thread if I can't find an obvious solution.

I don't have a booted linux machine handy, but df and df -lh show everything as well.  The -lh tag makes it easier to read.

Ok, but what about partitions that aren't part of the filesystem?

I have a 32 gb hard drive.  df can account for only 26 gb.  Where's the rest?  I assume that at least some of it is a swap space.  But 6 gigs for swap?  That seems unlikely.

What's the standard linux tool for partitioning a disk?  Google has been remarkably unhelpful.  Most info is devoted to partitioning a disk prior to installation, not viewing partitions on a system that's already been setup.

gparted is probably your best bet

I likes mine.  The keyboard takes some getting used to, but other than that it's a really cool tool/toy.

Go get one.  They're cheap enough.

I'm starting to view mine more and more as a tool. I don't even notice it in my work bag, and as we're somewhat limited on machines and space then I can set it up anywhere and check email, research etc at work. I've found it to be useful in several situations. I didn't find the keyboard on the Acer to be much to adapt to (the Dell is apparently slightly odder), but the mousepad and buttons did take some getting used to.

Ha!  I just figured it out.  Turns out 2swap was right, fdisk is the answer.  Thanks everyone.

When it comes to computers, 2swap is always right. Trust me on this one. =D
