How to mount additional Harddrive to CentOS cPanel

Under SSH, run below command to see your current hard drive partitions:

df -h

examples:

/dev/sda1             20G  4.7G   15G  24% /
tmpfs                 245M     0  245M   0% /dev/shm
/usr/tmpDSK           485M   11M  449M   3% /tmp

and then Run

fdisk -l

the output:

 Disk /dev/sda: 21.5 GB, 21474836480 bytes
255 heads, 63 sectors/track, 2610 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00000000

    Device Boot      Start         End      Blocks   Id  System
/dev/sda1   *           1        2550    20480000   83  Linux
/dev/sda2            2550        2611      490496   82  Linux swap / Solaris

Disk /dev/sdb: 10.7 GB, 10737418240 bytes
255 heads, 63 sectors/track, 1305 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x2038f030

    Device Boot      Start         End      Blocks   Id  System
/dev/sdb1               1        1305    10482381   83  Linux

to mount properly, you have to partition the harddrive first.

fdisk /dev/sdb
n
p
1
press enter twice
wq

and then format the hard drive

mkfs.ext3 /dev/sdb1

and mount it as a backup drive:

mount /dev/sdb1 /backup/

auto load this harddrive when server restarts:

echo "/dev/sdb1 /backup/ ext3 defaults 0 0" >> /etc/fstab

and done

In your WHM/Cpanel, you should see output like this:

/dev/sdb1 /backup 2% (154,232 of 10,317,828) 
/dev/sda1 / 24% (4,852,624 of 20,469,760) 
/tmp /var/tmp 2% (10,576 of 495,844) 
/usr/tmpDSK /tmp 2% (10,576 of 495,844)
