UNIX for Advanced & Expert Users

Hello All,
I'd like to know how can I transfer users from one partition to another. e.g:
# cat /etc/fstab gave something like this

/fs/garcia ext3
/fs/hendrix ext3
/fs/lennon ext3

These are some of the partitions in my server.Now I ran out of space in garcia and the users in garcia are not able to receive mails coz they ran out of quota. It would be of great help if someone could enlighten me how to transer or move users from (say) garcia to hendrix, i.e a non destructive transfer. Thanks a zillion in advance .

just change their ~home in /etc/passwd and move their home dir to the new filesystem. And you might have to manually change their group ID as well.

thats it!

if you don't want to change their home directory entries, you can also move the users' home directories to the available filesystem and just create a link to it on the old filesystem ... be careful with the "rm -rf " ... (check the right tar options/syntax for your os) ...

Code:

cd /fs/garcia
for userdir in user1 user2 user3 ...
do
    tar cvfp - $userdir | (cd /fs/lennon; tar xvfp -)
    [ -d /fs/lennon/$userdir ] && rm -rf $userdir
    ln -s /fs/lennon/$userdir $userdir
done

Thank you so much just ice.

Thank you so much magnus, your tip was greatly useful.
