Ran out of room

[Sasquatch]

It seems I goofed when I partitioned this laptop during the original install. I now find myself completely out of space to do anything because there's no room left on the / partition for tmp files or other newly installed stuff. I edited fstab to move /tmp to a ramdisk. But that didn't free up much space on the / partition or create much space in /tmp because there's not much available ram in this machine.

Is there anything I can do to fix this without needing a complete reinstall? I have already removed a bunch of things I added as dependencies for manually installed programs. So it's showing significantly more space now than it was at first. But it's still not sufficient.

Code: Select all

$ df
Filesystem     1K-blocks     Used Available Use% Mounted on
/dev/sda1       15355900 15042276    313624  98% /
/dev/sda3      227690472 31245804 196444668  14% /home
tmpfs             817304        0    817304   0% /dev/shm
tmpfs             817304   331264    486040  41% /tmp

You could resize sda1 and sda3 making sda3 smaller and sda1 larger, but it a little tricky. I suggest you post the output of

Code: Select all

$ sudo fdisk /dev/sda

so we can see the complete map of the disk.

Next time, do not set a separate /home partition.

As an ugly workaround you could copy some big directory like /usr to /home/usr (be careful to preserve ownership and permissions).

Then make a symink:
sudo rm -r /usr # Be sure that everything has been properly copied to /home first !!!
sudo ln -s /home/usr /usr

PS At second thought maybe it's not a bad suggestion as during startup possibly some files in /usr are needed before partition that hosts /home be mounted. Oh, well...

First run:

Code: Select all

sudo spi --clean

That will probably reclaim a lot of space. After that you can take a look in /var, maybe there are huge logs generated in /var/log for some reason. Using the du command will probably reveal where the most data is used.

I find it hard to believe that you have filled up 15GB. In my current system I have something like 11GB and it feels that I have almost everything installed.
But if you still need more space, you can definitely move your /usb partition inside your home. You can add this in your /etc/fstab:

Code: Select all

/home/usr /usr none bind

and then from

Code: Select all

sudo init 1

or from a live system, you can move your /usr to /home/usr

Code: Select all

mv /usr /home/
mkdir /usr

(adjust the paths for your HD in a live system)

Then

Code: Select all

reboot

and it should be ok.

No, nothing /usr is needed for mounting partitions. You can even rename/delete your /usr and your system will boot. X won't launch, but basic command line functionality will be there (everything in /bin and /sbin).

Welcome to fdisk (util-linux 2.21.2).

Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.


The device presents a logical sector size that is smaller than
the physical sector size. Aligning to a physical sector (or optimal
I/O) size boundary is recommended, or performance may be impacted.

I'll say! I went from 98% usage to 40%!

Code: Select all

[~]$ df

/dev/sda1       15355900  5988900   9367000  40% /

/var doesn't seem to be the problem.

I find it hard to believe as well. I haven't installed that much. And what I have installed has mostly gone to my /home directory. But the df output tells the story.

But if you still need more space, you can definitely move your /usb partition inside your home. You can add this in your /etc/fstab:

Code: Select all

/home/usr /usr none bind

and then from

Code: Select all

mv /usr /home/
mkdir /usr

and it should be ok.

How does that affect the PATH when launchers or other programs try to find programs that should be in /usr? I might try it. But after the way spi cleaned things up I don't really need that much space.

It doesn't. /usr will still be /usr. No need to do it if you don't have to though.

Then I won't. The spi command gave me plenty of room for what I need. I guess I'll just have to make a habit of running that every so often. Thank you very much.
