Updating the server

Install yumex (YUM eXtender GUI for yum)

sudo yum install yumex

Install new hard drive

After plugging in new hard drive, find the drive by typing

ll /dev/sd*

The new drive show show up here in this list. In this case, it is /dev/sdc

fdisk /dev/sdc

Using fdisk, create a new ext3 partition containing the entire hard drive. This actually reserves 5% of the disk for root. To remove this reservation, use tune2fs to set this to 0.

tune2fs -m 0 /dev/sdc1

Now create a new mount point in /media..

mkdir /media/new_drive

Edit /etc/fstab to add the new drive, such as the line

/dev/sdc1 /media/new_drive ext3 defaults,user,rw 0 0 

Now mount the new partition using

mount /media/new_drive

Use df to make sure the new drive is up and you have the right amount of free space

Filesystem            Size  Used Avail Use% Mounted on
/dev/sda1              99M   87M  7.5M  93% /boot
/dev/sdb1             459G  232G  204G  54% /media/sdb1
/dev/sdc1             917G  109M  871G   1% /media/hdock
