[DONE]low disk space on "filesystem root"

[robertbond]

hello i need help, every time I turn on mageia there's notif "Low disk space on filesystem root, the volume filesystem root has only ... disk space". how to resolve this problem, when I installed mageia 4 root is 12 GB, now has only 350.9 MB....

[jkerr82508]

To find out which directories are using most space, execute as root:

Code: Select all

du -akx / | sort -nr | head -n 25

This will tell which directories are using most space.

How you should proceed from there depends on the result of that command.

I will mention that my own Mageia 4 installation occupies 14 GB. Your problem easily could be that you need to enlarge the partition.

hei jkerr82508 thanks for your responses, I run that command and this is my result...

hei jiml8, do you think I need reinstall my mageia and increase my root partition?

[jkerr82508]

3371924 /root

A /root directory of over 3GB is very strange - mine is about 3MB.

I'm not familiar with AndroidStudio, but I suspect that .AndroidStudioBeta belongs in your home directory and not in /root. I don't use Dropbox, but I suspect that Dropbox does not belong in /root either.
How did you install those?
Are you running them as root, if so why?

I think that you should carefully review the instructions for installing and using those applications. You may have to remove and re-install them both.

Edit: fixed typo

[doktor5000]

I agree. Mine is about 1.2 Meg, though I did recently clean up a bunch of old stuff in there that reduced its size considerably.

That said, even removing all that stuff from /root will still leave you with a pretty crowded / . If it were me, I would enlarge the partition...which you can do without a reinstall.

[daniewicz]

Can you explain how to enlarge a partition without a reinstall? Thanks!

[doktor5000]

Pretty simple - enlarge the partition, then partprobe for the kernel to rescan the partition tables and then run resize2fs (or the respective tool if you don't have ext filesystem).

for jkerr82508 android studio is app for develop android, it's like ecilpse. for dropbox i follow the instruction here http://forum.linuxbsdos.com/topic/124/h ... n-mageia-4

for doktor5000 can you make step by step, I never enlarge the partition for sure ...

[jkerr82508]

dropbox i follow the instruction here http://forum.linuxbsdos.com/topic/124/h ... n-mageia-4

You will note on that page:

All command will be typed as a regular user, so you do not have to su to root.

the root folder of your home directory

is /home/username (replace username with the name that you log in as) and not the /root directory.

The AndroidStudio download can be extracted to /opt, which requires root privileges, or to your home folder, which is easier and does not require root privileges.

You should run both of these applications as your regular user, and not as root. You must have been root at some point in order to have these directories appear in /root. Only the root user can write to /root.

We have instructions here how to install dropbox, please first have a look at those. Problem is we can't really support some foreign howtos.
So if you have issues with that instructions, please comment in their forum and provide them feedback if any parts were unclear to you.

For partition resizing, first you should clean up that mess with the android studio, then we'll have a look again.

@jkerr82508:

Code: Select all

du -smx /* | sort -nr

is less typing but easier to read IMHO - even if it's not posix'ish

Thanks for that. I can see it being useful. However, it only gives the size of top level directories. In this case we would have had to ask for it to be run a second time on /root in order to see the cause of the problem.

In order to use either of those commands, I have to copy and paste from my Notes. These days my memory cells leak information faster than they absorb it.

On systems to which I have access, I prefer to install ncdu, which, in addition to providing a "pretty" display, enables one to drill down to the offending directory.

Thanks for that one, didn't know that
I'm often using baobab, as I can see better what's what there and the general overview is better IMHO.

[robertbond]

for all
yes after reinstall dropbox my root space is increase 700 mb, I think I should reinstall android studio too, but it need more time for set up. For me this problem is done, thanks for response..

good day
