SOLVED

please see the bottom answer for my solution

After I use GParted to fix my partition(GParted ran well but my laptop shutt down because it ran out battery power and didn't finish the process copying my other partition, details),

I notice that I got 10GB increase in my Ubuntu partition, then I checked and found 1 suspicious file with size 140TB in /proc...

Is this a problem?

ubuntu 12.04 lts 64bit

UPDATE

I hope these details can help 

sudo fdisk -l

Partition table entries are not in disk order

ADDED

I think the sudden increase 10GB in my Ubuntu partition is because unfinished GParted process, I currently have 27GB in used (when I right click in filesystem then check properties) , but disk analyzer says another thing(it says I am only using 12-13GB)

  • Looks like something has become corrupt on that drive. Backup data and start again :) – SabreWolfy Mar 02 '13 at 19:21
  • oh God.. that's my ubuntu partition, i used gParted to fix misaligned partition before i realized that.. what should i do? – mohur Mar 02 '13 at 19:22

    If gparted did not finish running, then anything is possible. There is no way to know that everything on that drive is fine. It's a 1TB drive, so how can you have a 140TB file. Have you run fsck on it? – SabreWolfy Mar 02 '13 at 19:24
  • Searching on Google for "huge kcore file" shows lots of results. Maybe check some of those too. Not all files in /proc are real files. – SabreWolfy Mar 02 '13 at 19:26
  • erm please see my post update, gparted did not finish running when i was fixing the other partition which is /dev/sda8, then i check all the data in /dev/sda8 no corrupt, and ubuntu runs normally no error all software is good.. – mohur Mar 02 '13 at 19:28
  • Don't run fsck on a mounted partition. – SabreWolfy Mar 02 '13 at 19:47
  • oh ya my bad forgot lol sry, but i read some documentation about fsck... i dont know but i just dont understand how to use it correctly, can u please give me what arguments after fsck? in the documentation it has alot of arguments after the word fsck and i dont know which one to use – mohur Mar 02 '13 at 19:52
  • fsck can be run from Grub (see this question for a screenshot). – Takkat Mar 02 '13 at 20:23

    This is probably obvious, but I'll mention this for the future visitors just in case: you should never ever EVER run gparted while on battery power :) – Sergey Mar 03 '13 at 00:03
  • Please add solutions as answers, not in original question. – Mateo Mar 03 '13 at 14:51

I don't think that 140TB kcore is a problem.

As gropiuskalle said in one forum: "/proc/kcore is an image of your RAM created by the Kernel to give you respective information, it's not actually a file you could delete but a virtual filesystem and it does not actually take harddisk-space."

Also, mine kcore has the same size as yours:

enter image description here

That doesn't mean you don't have other problem caused by an interruption of gparted.

  • ah yes, after my gparted process didnt finish correecty(especially when it was copying with 2MB / s on my /dev/sda8) i start linux and realized i got about 10GB increase in use for root( /dev/sda5 ) partition.. what should i do? – mohur Mar 02 '13 at 19:43
  • Two suggestions: 1) Boot from a live cd and do a filesystem check; or 2) Backup your files and re-install Ubuntu (best option for me). – desgua Mar 02 '13 at 20:10

SOLUTION

finally i managed to find why +10GB sudden increase happened to my ubuntu partition, if u guys have any trouble/problem like me (gParted did not finish) please read this i hope it can help u.

explanation of my solution as follows :

gParted did not finish when moving my /dev/sda8 , then there's impact on my ubuntu root partition(+10 GB) i dont know why this happens but i believe its something with gParted.

when i check my trash(both user's and root's) ~/.local/share/Trash and /root/.local/share/Trash respectively, there's file(s) / folder(s) with size like 14GB (please note that i cleaned up my trash before i used gParted, and im pretty sure my trash is empty and my ubuntu partition only use less than 15GB) i just simply delete it and like normally i got free space.

note : i simply delete it because i know when i was having trouble with /dev/sda8 , there isn't any important files in that partition.
