Minimal Ubuntu Takes Up 22 GB of Space

[Spiralagnus]

I just did a minimal install of Ubuntu 12.04 with the XFCE interface on a new computer with a 1.5 TB hard drive.


df -hreveals that 22 GB of hard drive space are used up for the primary partition /dev/sda1:


Filesystem Size Used Avail Use% Mounted on
/dev/sda1 1.4T 22G 1.3T 2% /
udev 3.8G 8.0K 3.8G 1% /dev
tmpfs 1.6G 348K 1.6G 1% /run
none 5.0M 0 5.0M 0% /run/lock
none 3.8G 0 3.8G 0% /run/shmalthough totaling all of the directories in the root folder using


du -h / --max-depth=0reveals that the root directory is only taking up about 1.1 GB of space (as the instructions said a minimal installation would):


1.1G /I tried resizing the reserved space using


tune2fs -m 1 /dev/sda1 to 1%, but it made no difference. I'm still getting that 22 GB are used. What's taking up that extra 21 GB of space? Any thoughts?

Thanks to the community in advance for your help.

Did you set the size of the partitions manually or did you just go with the defaults? I'm wondering if you chose defaults a % of total available disc is automatically allocated? I'm sure someone will know for sure ...

Try using


sudo du -h --max-depth=1 /

The hard drive is a single partition containing the Ubuntu install. I just chose that option and went with the defaults.


Try using


sudo du -h --max-depth=1 /

Done. Here's the output. As you can see, the total size of the folders doesn't add up to anywhere near 22 GB. (I've installed a bunch of software since my last post, so the total size is a bit larger than the 1.1 GB I quoted earlier but still much less than 22 GB.)

I was just looking at fdisk and noticed this:


Device Boot Start End Blocks Id System
/dev/sda1 * 2048 2914025471 1457011712 83 Linux
/dev/sda2 2914027518 2930276351 8124417 5 Extended
/dev/sda5 2914027520 2930276351 8124416 82 Linux swap / Solaris

Is it possible that Ubuntu is reserving this much space for swap? If so, why would an OS like Ubuntu need that much swap space, and is there a way to change it?

Note that your output is in "Blocks" and not in a human friendly measurement. Not sure the command you are using but there will be a switch to make the output appear in KB/MB/GB ... Best check the man page for the command to see all the switched.

fdisk doesn't appear to have a human-readable option, but it doesn't matter. Upon closer inspection, I realize the swap space is a separate partition from the primary one, and it's the primary one that's unusually big. Any other thoughts as to why the partition reads as 22 GB full?
