Partitioning and Formatting Second Hard Drive in Linux - (ext3)
by Jeff Hunter, Sr. Database Administrator
This article presents the commands used to partition and format a second hard drive in Linux using the ext3 file system. For the purpose of this example, I installed a second hard drive in a Red Had Linux system where the drive is recognized as /dev/hdb. I want to make only one partition on this hard drive which will be /dev/hdb1.
First, you will need to run the fdisk command in order to partition the disk. For this example, I only want to create one ext3 partition. Here is an example session:
The next step is to create an ext3 file system on the new partition. Provided with the distribution is a script named /sbin/mkfs.ext3. Here is an example session of using the mkfs.ext3 script:
Now that the new hard drive is partition and formated, the last step is to mount the new drive. For this example, I will be mounting the new hard drive on the directory /db.
Edit the /etc/fstab file and add an entry for the new drive. For my example, I will create the /dev/hdb1 entry as follows:
After making the entry in the /etc/fstab file, it is now just a matter of mounting the disk:
[root@racnode1 ~]# mount /db [root@racnode1 ~]# df -k Filesystem 1K-blocks Used Available Use% Mounted on /dev/hda3 37191660 11016692 24285724 32% / /dev/hda1 101089 12130 83740 13% /boot none 515524 0 515524 0% /dev/shm /dev/hdb1 38464340 32828 36477608 1% /db
