du -h /fullfilesystem is a good start, possibly with
--max-depth to limit the output.








With # du -h --max-depth=1 you can find what directory is taking all
of the space. Next is take the right action, by emtying /* deleting
the file, or moving the directory to an new disk.



Also when you* reply on en mail please place your text below.

Too generic. Not enough information.

What you would do after you found a full filesystem? It is just a general question that was asked in my class of operating systems and nobody had an answer.

Thanks,

You look for the biggest file. (I feel a GOML moment approaching.)

I currently have this problem on two of my disks. As I see it, I have 3
realistic choices: delete enough stuff to free up a realistic percentage if
the disks; buy myself 2 new larger disks; and copy a large chunk of stuff I
want to keep, but only need rarely, onto another (external?) disk. I am
trying the last first, and have bought an external drive. But I haven't yet
done it, and may not succeed in moving enough!

It all depends on context, you'll need to add a little more detail. For
instance:
As an administrator, you'd probably go find big files and go shout at
their creator.

As an application developer, you'd need to gracefully handle the error.

Depends. Best case, you built your system using LVM and have reserved
space. You can check this using the df command. If your filesystems
start with /dev/mapper, then you are using LVM. You can check for free
space using the vgdisplay command (as root):



# vgdisplay

...Snip...

* Alloc PE / Size****** 96637 / 377.49 GiB

* Free* PE / Size****** 80065 / 312.75 GiB



The free PE/Size line shows you the available space. You could then extend the filesystem that is having issues:



# lvextend -L+10G /dev/VG00/foo



If you are using standard hard drive partitions (/dev/sda1, /dev/sdb2, etc), then you have to do it the old school way.

Using a tool like df, find a directory tree that is large enough that moving it off of the filesystem would make a difference, then copy it to a partition with more space, then symlink it back to its original location.


This is an older and uglier way to do it as you could, over time wind up with a bunch of these symlinks all over your hard drive.
