not enough space problem & moving to another hdd question

[mantasman]

hi,
i had many problems with local www server today. php sessions didnt work, mysql didnt start at all... so, i've lost ~4-6 hours when i was messing around it . later i've found that there's no enough space on my / partition .
most strange think is that there's 230 megs of free space here (as gnome system monitor claims). i can move or copy files in terminal (as root) but i cant do same things in nautilus (as root too).
how can i disable this quota?

and the second question is...
is it possible to easily move to another partition? something like mv / /mnt/another_partition.

Hi mantasman,

1) To see what your actual usage is:

Drop down out of gnome (Kill the gnome processes altogether) back to the command line and type:

df

This should give you an accurate indication of what space is remaining on your mounted drives.

du -chs /*

That will tell you what directories are using how much space and what the total usage is.


2) To mount a directory somewhere else

- Shut down your machine and install an additional drive
- boot with a live cd and partition this (new) drive as you see fit. make sure you don't remove your existing partitions on your original disk!
- mount the existing root dir / and the new partitions (as something like: /newpart1, /newpart2, etc <- these are temporary mounts)
- copy the data from /home (an example) to /newpart1. also add an extra file to the /newpart1 directory called new.txt
- rename the directory /mnt/gentoo/home to /mnt/gentoo/homeold
- alter /mnt/gentoo/etc/fstab so that /home (again just an example directory) is mounted as /dev/hdb1 (the newpart1 partition). You'll have to add this line to the fstab file as it is a new mountpoint.
- unmount all mounted partitions (as in the final step in the actual live cd install)
- reboot
- when your system comes up go to the command line and type mount. this will show you what drives / partitions are mounted. in my example you should see /home mounted on /dev/hdb1.
- ls /home and you should see the file new.txt. if you see this file you've successfully mounted the new partition on a different drive.
- once you're satisfied the correct partition is mounted you can remove the /homeold directory and you've freed up space on your old drive.

Good luck!

i already have my /home on another partition because i us e same /home on ubuntu & gentoo.
but is it possible to move / (/etc, /usr, /bin, /sbin....) to another directory?

thanks. i've just succesfully moved /tmp to another partition. will try to do same with other folders on tomorrow.

This has been a helpful thread. I'll be doing something similar soon. My question:

Is there anything special that I need to be aware of if I'm using a different filesystem (reiserfs instead of ext3) on my destination partition -- other than making sure fstab is updated, that is?

Thanks.
