SOLUTION: CentOS can not install on drives larger than 2TB; downgraded drive to 2 TB.

I recently rented a dedicated server and bought a large hard disk size upgrade (3TB).

But, linux reports I have very little space, here is the results of "df -h"

Filesystem            Size  Used Avail Use% Mounted on

/dev/sda3              69G  6.1G   60G  10% /

/dev/sda1             487M   23M  439M   5% /boot

tmpfs                 989M     0  989M   0% /dev/shm

My questions:

  1. Do I need to find and mount the hard drive, if so, how?

  2. Or, did the server provider make a mistake?

Edit: Here is the output of "fdisk -l", as requested:

Disk /dev/sda: 80.0 GB, 80000000000 bytes
255 heads, 63 sectors/track, 9726 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Device Boot      Start         End      Blocks   Id  System
/dev/sda1   *           1          64      514048+  83  Linux
/dev/sda2              65         574     4096575   82  Linux swap / Solaris
/dev/sda3             575        9725    73505407+  83  Linux

Edit2: Here is the invoice I paid showing I should have a 3TB drive:

Did they add a drive or replace a drive? The output you're showing only shows a single hard drive, with partitions 1 and 3 mounted, which was probably you're existing drive. I'm going to guess that you now have another drive, likely at /dev/sdb that will need to be formatted and mounted. Note that since you have a dedicated server, that management usually falls upon you . . . –  ernie Jul 11 '13 at 20:18
    
Yep, that's showing an 80GB drive . . . it's also not clear if the drive has hot added or not, if the system needs a reboot to see the drive, etc. fdisk also won't work on GPT drives, which is what you'll need for a 3TB drive, so you should probably use parted –  ernie Jul 11 '13 at 20:25
    
@ernie's first post: When I rented the server, I choose to upgrade my primary drive from 500GB to 3TB. –  AndrewGeez Jul 11 '13 at 20:25
    
Are you sure it was a physical drive upgrade, and not a storage or transfer limit upgrade? The 500GB or 3TB may be offered elsewhere . . . the output of mount or df -h may provide more info . . . –  ernie Jul 11 '13 at 20:27
    
Yep, I have posted the invoice. –  AndrewGeez Jul 11 '13 at 20:33

Can you post the output of sudo fdisk -l?

You will likely need to format the drive and create a filesystem on it, before mounting it into your current filesystem.

Disclaimer: I take no responsibility for any data loss herein.

Assuming your second drive shows up as /dev/sdb and you want to use the ext4 filesystem and mount as /mnt/bigdrive (all commands being run as root):

fdisk /dev/sdb
n (create new partition)
p (primary partition)
1 (first partition)
t (change partition type)
83 (Linux partition type)
p (print the current partition table to verify)
w (write partition table to disk)

mkfs.ext4 /dev/sdb1
mkdir -p /mnt/bigdrive
mount /dev/sdb1 /mnt/bigdrive
echo "/dev/sdb1 /mnt/bigdrive ext4 defaults 0 0" >> /etc/fstab

Documentation on how to use fdisk is here. I suggest you read it before running any of the commands above - needless to say that one slip could lose you data!
