Did you make /dev/sda5 too small? if this is /var or /tmp
you need a fair about of free space or you can get out-of-space
errors for the temporary files.

'Failed to cleanly unmount' ?
Parted needs the partitiions you are working to me unmounted.
Andrew - does Parted check for this ?
Use 'umount /dev/sda5' to unmount minor 5, or boot using the
parted root disk (This is needed to if you wish to work on /, unless you have
a spare partion which can be made / [Linux/BSD dual boot systems can be like
It may be possible that minor numbers changed, if this happend, edit your
/etc/fstab to refelect the new minor numbers.
If you run parted within 'script', and post the entire session here, we can
give more help on whats going wrong.
Possible instructions - take these with 1 Mol NaCl - they are of the top of
my head. They will fail if there isn't enough free space on /dev/sda5
#First unmount the affected partions - 3 needs to be moved, 4 (an exteneded
partion, containing 5 to 9) needs resized
#as the free space from 5 needs to moved to the end of 2
umount /dev/sda2 /dev/sda3 /dev/sda5
#Half the size of /dev/sda5
resize 5 1106 6106
#Move it to the end
move 5 6106 10260
#resize 4 (it contains 5 to 9)
resize 4 10260 17343
move 3 1082 6082
resize 2 1106 6082
#inspect fdisk -p and /etc/stab to make sure that
#the minor drives haven't changed numbers/
#remount 2, 3, 5
mount /dev/sda2 /dev/sda3 /dev/sda5

As a sysadmin, what would you say to a luser
who came to and said.
