mohammad alsharqi;

The instructions are to add the capacity to your system, how you use that added capacity is at your discretion.

Specific questions get specific answers.

hope this helps

If you partitioned the first disk using LVM when you installed the system then its easy to combine the drives.

If you aren't using LVM then there is no easy way to simply pool the drives together, your best bet would be to migrate the contents of the squid cache directory to your new drive before mounting it under the original directory location. This method would give you 2TB for just your cache, the rest of your OS and its data would still be on the original 500GB drive.

If you must have both drives pooled together to give you 2500GB of continuous storage space then it would be easiest to reinstall using LVM, and then restore your current data from your last backup.

Without knowing your exact setup I can't give you the commands you need.

If you can post back with the output of the following commands I'll get back to you (can you post your output in between [CODE] [/CODE] tags to make it easier to read please).

sudo parted -l
sudo pvdisplay
sudo vgdisplay
sudo lvdisplay
