How to format a partition to ext3 in fedora

How to format a partition to ext3 in fedora ?
How to make a partition in linux ?

I just added 500GB to this server, and I’m going to make a partition and format it then use for backup my data.

First, you have to list out the hard disk drive that plugged in.

fdisk -l

[root@server ~]# fdisk -l
[adrotate banner="1"]
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 13 104391 83 Linux
/dev/sda2 14 9726 78019672+ 8e Linux LVM

Disk /dev/sdb: 500.1 GB, 500107862016 bytes
255 heads, 63 sectors/track, 60801 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

 

Disk /dev/sdb doesn't contain a valid partition table

You see, It will show that it doesn’t contain a valid partition table. So we need to create the partition for it.


[root@server ~]# fdisk /dev/sdb
Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel
Building a new DOS disklabel. Changes will remain in memory only,
until you decide to write them. After that, of course, the previous
content won't be recoverable.

The number of cylinders for this disk is set to 60801.
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)
Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite)

Command (m for help): m
Command action
a toggle a bootable flag
b edit bsd disklabel
c toggle the dos compatibility flag
d delete a partition
l list known partition types
m print this menu
n add a new partition
o create a new empty DOS partition table
p print the partition table
q quit without saving changes
s create a new empty Sun disklabel
t change a partition's system id
u change display/entry units
v verify the partition table
w write table to disk and exit
x extra functionality (experts only)

Command (m for help): n
Command action
e extended
p primary partition (1-4)
p
Partition number (1-4): 1
First cylinder (1-60801, default 1):
Using default value 1
Last cylinder or +size or +sizeM or +sizeK (1-60801, default 60801):
Using default value 60801

Command (m for help): w
The partition table has been altered!

 

Calling ioctl() to re-read partition table.
Syncing disks.

You can check again by using fdisk.

fdisk -l


[root@server ~]# fdisk -l

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

Partition created completed, the next step I’m going to format it as ext3 file system.
I’m going to use this command to format.

mke2fs -j /dev/sdb1


[root@server ~]# mke2fs -j /dev/sdb1
mke2fs 1.39 (29-May-2006)
Filesystem label=
OS type: Linux
Block size=4096 (log=2)
Fragment size=4096 (log=2)
61063168 inodes, 122096000 blocks
6104800 blocks (5.00%) reserved for the super user
First data block=0
Maximum filesystem blocks=0
3727 block groups
32768 blocks per group, 32768 fragments per group
16384 inodes per group
Superblock backups stored on blocks:

Writing inode tables: done
Creating journal (32768 blocks): done
Writing superblocks and filesystem accounting information: done

 

This filesystem will be automatically checked every 26 mounts or
180 days, whichever comes first. Use tune2fs -c or -i to override.

[adrotate banner=”2″]

It is done. If you want to use this partition, you have to mount to some where.

[root@server mnt]# mkdir /mnt/sdb1
[root@server mnt]# mount /dev/sdb1 /mnt/sdb1

Now you can use df to check all the volume space

[root@server sdb1]# df
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/mapper/VolGroup00-LogVol00
73545144 63807800 5941172 92% /
/dev/sda1 101086 16313 79554 18% /boot
tmpfs 1684508 0 1684508 0% /dev/shm
/dev/sdb1 480719056 202800 456097056 1% /mnt/sdb1

It is done. Please click ‘Like’ if this article can help you.
