File system root low disk space

[abexman]

Hello,

OK as I said elsewhere am having this issue on two machines with low disk space on file system root. I cannot access anything useful in disk space analyzer because it hangs showing me usage (other post). In gparted it does seem to show me that I have space in my root??

Below are some screenshots. On this machine my Windows partition is running out of space, but why would that affect root (not the case on the other machine)? Also on this machine I am having issues with the partition getting an underscore and creating two folders under /media. Not sure if its related or if it can be fixed or matters.

4.9GB sure isn't very much for a root partition, I'd usually recommend something around 10-20GB for root. So it's not a surprise you are running low on space.

Try uninstalling old kernel packages, cleaning apt's cache, and check sure there's nothing in root's trash directory. That should give you at least some space back.

[ajgreeny]

Do you have any idea what sda7 might be?

There are 7.81 GB of "unknown" usage as far as gparted is concerned, and as it is next door to your 4.9GB root partition it would be relatively easy to delete sda7 and enlarge sda5, your root partition. However that is totally dependent on what the partition might contain.

What does

sudo fdsik -l

show please, as that may give us some clues.

[abexman]

Crap. Had followed this install guide in trying to spec partition sizes, where they used ~5gb.
http://www.dedoimedo.com/computers/d...-7-ubuntu.html

For that command I get
sudo: fdsik: command not found ??

I think the sda7 is just leftovers. I probably did not do a very good job setting up the partition using gparted. I was a little overeager to get Ubuntu up and running. I guess I can try and redo the partition.

Looks like I can resize using the Live CD & gparted? Assuming the partition goes OK, is that it? I won't have to repair the install after resizing root?

abexman; Hi !

"fdsik": slip of the fingers .....correct to be

sudo fdisk -l

lower case "L"
Re partitioning: Yeah, live disk (so working with non mounted partitions); delete sda7 and enlarge sda5.
Worst that should result is having to re-install grub. If so, no big deal.

The learning experience is worth all the effort !

Yes , there is a misspell there. It is

sudo fdisk -l

Yes you can resize (expand) the / root partition , but carefully. DO NOT ever resize from the beginning to the end. Just expand the end of partition.
Of course you must have space (or steel space from other partitions) and important thing is that This space must be NEXT to / root partition.

Maybe it will need to move some space.

IF you are not sure , the best thing is to Attach an image of Gparted here and we will see.

Thanks
