First you need to use a disk partitioning tool like fdisk or cfdisk to
partition the new drive. Depending on the size of the drive should
determine how you partition the drive. If this is a new drive like 80GB
I don't think you want a home partition of that size unless you really
require a home partition that big. You could partion the drive into 4
20 gig chunks and use accordingly. The choice is totally up to you.
I personally like to have the following partitions:
/ 100M
/boot 120M
/usr 4G
/usr/local 2G
/var This depends on what will be stored on /var
/var/www Website
/var/lib/? Database Storage
/home Depends on the number of users
swap 120M is usually good.
/ /boot /usr /usr/local sizes are basically fixed on what you install on
them. On the other hand /home could be spread across several partitions
like /home/a /home/b /home/c or whatever other scheme you want to use.
/var also could be divided up into several partitions if you are using a
database like postgres which stores the data in /var/lib/postgres/data/
You could make this as a separate partition.
Anyway, after you decide the partitions along with the sizes you require
run your disk partitioning software and partition the new drive.
After the new drive is partitioned, then you need to create a filesystem
for each partition.
I like the ext3 journal partition
mke2fs -c -b 1024 -i 1024 -m 1 -j /dev/hdb1
-c Checks for bad blocks. There are some that don't think
this is necessary for a new drive, but I do it anyway
-b block size 1024 being the smallest. For home
directories I think this is a good size.
-i inode size in most cases should be the same as -b
-m the percentage reserved for the lost and found directory
-j create a journal
You have to do this for every partition that you created.
Let's say that you decided that /dev/hda1 will be the new home directory
first you should mount it like:
mount /dev/hda1 /mnt
# copy everything from /home to the new partition
cp -a /home/* /mnt/
Next edit /etc/fstab to automatically mount your new home paretition:
/dev/hdb1 /home ext3 defaults 0 0
The above line instructs linux to mount /dev/hdb1 as /home on bootup
I hope that this answers any questions that you have.
