No enough space error when trying upgrade ubuntu from 8.04 lts to 10.04 lts


Dear all,

When I try to upgrade my ubuntu studio from 8.04 LTS to 10.04 LTS, exception as following occurs and upgrade interrupted.
Insufficient disk space.
4153M free space under root directory "/" is required for upgrade at least. Please use command "sudo apt-get clean" to clean up temporary package for previous installation.

I install ubuntu under RAID 1 and disk space information is as below.
I have much space under "/home" directory.
How could I use those space or move some space to root directory?
/dev/mapper/pdc_dgbbagea1
9698348 7066748 2142824 77% /
varrun 1892232 120 1892112 1% /var/run
varlock 1892232 0 1892232 0% /var/lock
udev 1892232 72 1892160 1% /dev
devshm 1892232 84 1892148 1% /dev/shm
lrm 1892232 44984 1847248 3% /lib/modules/2.6.24-23-generic/volatile
/dev/mapper/pdc_dgbbagea4
945587172 93526716 804405644 11% /home
/dev/mapper/pdc_dgbbagea3
9698380 1363364 7846240 15% /opt
gvfs-fuse-daemon 9698348 7066748 2142824 77% /home/flik/.gvfs

Thanks and best regards,
Flik

Just 2GB for a / partition? No wonder the thing is complaining.

If you use ext3 or ext4, you could use gparted and do some resizing. Or you could leave / alone and use gparted to split your home partition into two - one partition of, say, 5-6GB for /usr and the rest for /home - copy the files from /usr to your new usr partition and then edit /etc/fstab. The first approach would be the more convenient one, though.
In either case, you should copy/move the files in your home directory somewhere else to prevent data loss.

I would suspect you need to actually grow the root itself - regardless of mounts likes /usr. The installer is probably too stupid to work it out (case in point: Fedora 13 recommend half a Gig for /boot ).
You need to work out where the partitions are (physically) before you can plan how to move space around. Try "sudo fdisk -l"

Hi,

It seems a bit complex, I build all partitions on RAID10.
I could not adjust partition on RAID via "gparted".

Could you please give some advice to me.

Thanks and best regards,
Flik

I would recommend backing up your data to an external drive and doing a fresh reinstall of 10.04. This is the easiest way to take advantage of new features such as Grub2 and the ext4 filesystem.

Thanks for all your kindly suggestion.
I have given up to upgrade Ubuntu.
And I use Live CD to format the root partition since alternative CD could not format it properly.
It works fine to me now.
