Step One: Check the current had disk mount status:
command "df -h"
Sample Output:
"df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sda3 6.0G 5.4G 231M 96% /
/dev/sda1 2.0G 268M 1.7G 14% /boot
tmpfs 500M 0 500M 0% /dev/shm
"
Step Two: Check the hard disks attached to the server.
Command "fdisk -l"
Sample Output:
fdisk -l
Disk /dev/sda: 10.7 GB, 10737418240 bytes
255 heads, 63 sectors/track, 1305 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x000b3989
Device Boot Start End Blocks Id System
/dev/sda1 * 1 261 2096451 83 Linux
/dev/sda2 262 522 2096482+ 82 Linux swap / Solaris
/dev/sda3 523 1305 6289447+ 83 Linux
Disk /dev/sdb: 10.7 GB, 10737418240 bytes
255 heads, 63 sectors/track, 1305 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x079f9b62
Device Boot Start End Blocks Id System
Disk /dev/sdc: 10.7 GB, 10737418240 bytes
255 heads, 63 sectors/track, 1305 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0xe9614c39
Step Three: Find the unmounted hard disks from "fdisk -l"
Eg: "Disk /dev/sdb" and "Disk /dev/sdc"
Step Four: Format the disks to make linux filesystem.
Eg: "
fdisk /dev/sdb
The number of cylinders for this disk is set to 1305.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
(e.g., DOS FDISK, OS/2 FDISK)
Command (m for help): n
Command action
e extended
p primary partition (1-4)
p
Partition number (1-4): 1
First cylinder (1-1305, default 1): 1
Last cylinder, +cylinders or +size{K,M,G} (1-1305, default 1305):
Using default value 1305
Command (m for help): w
The partition table has been altered!
Calling ioctl() to re-read partition table.
Syncing disks.
--------------------------------------------------------------------
fdisk /dev/sdc

Step Five: Check current "fdisk -l" status
Eg:
"fdisk -l
Disk /dev/sda: 10.7 GB, 10737418240 bytes
255 heads, 63 sectors/track, 1305 cylinders

/dev/sda2 262 522 2096482+ 82 Linux swap / Solaris
/dev/sda3 523 1305 6289447+ 83 Linux
Disk /dev/sdb: 10.7 GB, 10737418240 bytes
255 heads, 63 sectors/track, 1305 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x079f9b62
Device Boot Start End Blocks Id System
/dev/sdb1 1 1305 10482381 83 Linux
Disk /dev/sdc: 10.7 GB, 10737418240 bytes
255 heads, 63 sectors/track, 1305 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0xe9614c39
Device Boot Start End Blocks Id System
/dev/sdc1 1 1305 10482381 83 Linux
"
You will find "/dev/sdb1 1 1305 10482381 83 Linux"
and "/dev/sdb1 1 1305 10482381 83 Linux" created.
Step Six: Use mkfs.ext3 command to build linux file system over "/dev/sdb1 and /dev/sdb1"
Eg:
"mkfs.ext3 /dev/sdb1
mke2fs 1.41.3 (12-Oct-2008)

"
Step Seven: Make directory to mound the two hard disks.
Eg:
"mkdir /mnt/diskone"
"mkdir /mnt/disktwo"
Step Eight: Mount the hard disk to created folders
Commands:
"mount /dev/sdb1 /mnt/diskone/"
"mount /dev/sdc1 /mnt/disktwo/"
Step Nine: Check the mount status:
Command" "df -h"
Eg:
"df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sda3 6.0G 5.4G 229M 97% /
/dev/sda1 2.0G 268M 1.7G 14% /boot
tmpfs 500M 0 500M 0% /dev/shm
/dev/sdc1 9.9G 151M 9.2G 2% /mnt/disktwo
/dev/sdb1 9.9G 151M 9.2G 2% /mnt/diskone
"
Step Ten: Commnds to unmount hard disks:
Commands:
"umount /dev/sdb1"
"umount /dev/sdc1"
Eg: "df -h"
"df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sda3 6.0G 5.4G 229M 97% /
/dev/sda1 2.0G 268M 1.7G 14% /boot
tmpfs 500M 0 500M 0% /dev/shm
