{{Note box|This HowTo uses the default naming of Hard Disks with PATA (IDE), when you have Sata Hard Disks the names of these drives are '''sda (/dev/sda)''' for the first, '''sdb (/dev/sdb)''' for the second, '''sdc (/dev/sdc)''' for the third...etc. You have to adjust these command lines to match the naming of your drives.}}
*It assumes adding one PATA (IDE) harddrive as master on the second IDE controller, but the process will be similar in other situations. More on that in step 2.1.

This will make you loose connection if you working through an ssh-client (like Putty). You need direct access to the shell to proceed.

{{Note box| All these operations should work through a remote SSH connexion, so you doesn't need a direct access to the server, except to mount a new hard disk}}

This entry assumes among other things that you will be running user and group quota, the "1" indicates it is a disk that should be backed up with dump, the "2" indicates fsck should be run as a second priority. If you wish to modify these parameters, ensure you fully understand them as these are crucial to your system's operation.

Similar to alternative 1, you can simply mount the disk for a specific iBay. If you need multiple iBays covered though it implies you have to create multiple partitions on the disk. The benefit like alternative one is simplicity of standard SME processes while limiting waste on your primary disk. The down side is inflexibility and waste on the secondary disk.

====Alternative 3: Mounting and Symlinking====

A much better approach is to leave the second disk mounted at /mnt/newdisk and to create symlinks (symbolic links) for specific ibays or user folders. The benefit is flexibility and efficient usage of the all disks. The down side is that you may have to make more modifications to ensure SME services and contribs work as expected (see also Optional Steps).

The following example shows you how to place the IBAYNAME ibay on the second disk using Alternative (3).
The following example shows you how to place the IBAYNAME ibay on the second disk using Alternative (3).
===== Create the necessary subdirectories on your second disk =====
mkdir -p /mnt/newdisk/ibays/IBAYNAME
mkdir -p /mnt/newdisk/ibays/IBAYNAME
===== Check the ownerships and permissions on the original directory =====
ls -l /home/e-smith/files/ibays/IBAYNAME
ls -l /home/e-smith/files/ibays/IBAYNAME
drwxrwxr-x 18 admin allstaff 4096 Sep 23 14:48 IBAYNAME
drwxrwxr-x 18 admin allstaff 4096 Sep 23 14:48 IBAYNAME
===== Change ownership as in the original =====
The "-R" (optional) means recursive, subdirectorys will be included in the command.
chown -R originaluser:originalgroup /mnt/newdisk/ibays/IBAYNAME
chown -R originaluser:originalgroup /mnt/newdisk/ibays/IBAYNAME
===== Set permissions to the ibay IBAYNAME as in the original =====
For help on this, look at bottom of this page. The "-R" (optional) means recursive, subdirectorys will be included in the command:
chmod 775 -R /mnt/newdisk/ibays/IBAYNAME
chmod 775 -R /mnt/newdisk/ibays/IBAYNAME
===== Copy the content to your new disk =====
cp -ai /home/e-smith/files/ibays/IBAYNAME/* /mnt/newdisk/ibays/IBAYNAME
a=archive option to preserve owner/group/permissions/links; i=interactive:
cp -ai /home/e-smith/files/ibays/IBAYNAME/* /mnt/newdisk/ibays/IBAYNAME
===== Check if all files have been copied correctly =====
diff -r /mnt/newdisk/ibays/IBAYNAME /home/e-smith/files/ibays/IBAYNAME
diff -r /mnt/newdisk/ibays/IBAYNAME /home/e-smith/files/ibays/IBAYNAME
===== Remove the original files =====
rm -rf /home/e-smith/files/ibays/IBAYNAME
rm -rf /home/e-smith/files/ibays/IBAYNAME
===== Create a symlink to the new location
ln -s /mnt/newdisk/ibays/IBAYNAME /home/e-smith/files/ibays/IBAYNAME
ln -s /mnt/newdisk/ibays/IBAYNAME /home/e-smith/files/ibays/IBAYNAME
===== Enable Wide Links for Samba (SME9) =====
config setprop smb WideLinks yes
expand-template /etc/samba/smb.conf
service smb restart
===== Test the new location =====
ls /home/e-smith/files/ibays/IBAYNAME
ls /home/e-smith/files/ibays/IBAYNAME
