Fedora Core 3 Re-partitioning hdd

**Computer_Freak** · 27-12-2010

Freshly I repartitioned the Hard Drive of a Fedora Core 3 box. Steps are given as follows to repartition presented Hard Drive, Adding up 3 fresh partitions, named as /home, /lfs and /livecd and every having size 10G, 6G and 1G correspondingly.

A. Preparation before repartition

To find out the existing partitions

Code:

# fdisk -l /dev/hda
Disk /dev/hda&#58; 40.0 GB, 40020664320 bytes
255 heads, 63 sectors/track, 4865 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Device 	Boot 	Start	End	Blocks	   Id	System
/dev/hda1   *	1	14	104391	   83	Linux
/dev/hda2		15	2569	20482875	   83	Linux
/dev/hda3		2570	2687	1020127+	   82	Linux swap
/dev/hda4		2688	4886	17470687+   5	Extended
/dev/hda5		2687	4870	17470656	   83	Linux

To find out the size of Hard Drive/each partition and the system of each partition

Code:

# df -hT
Filesystem 	Type   	    Size     Used      Avail     Use%     Mounted on
/dev/hda2      ext3        19G      3.6G      14G       19%        /
/dev/hda1      ext3        98M      15M       79M       17%        /boot
none           tmpfs       125M     0         125M      0%         /dev/shm
/dev/hda5      ext3        17G      1.5G      15G       11%        /home

B. Repartition Steps

1. Boot from the “init 1”, with one User Mode and while booting go to Bootloader window, choose the latest kernel and then press the "e" key in order to edit the commands for that kernel prior to booting. After that screen, select the line which has "kernel /vmlinuz.........." and press "e" key again. Going on next screen, Ending of the "grub edit -> kernel /vmlinuz..." thump space bar one time to obtain a space prior to typing and then type "init 1" devoid of the (quotation marks) and then press "Enter". At this moment coming to and fro on screen and a line with "init 1" shown at its end will be shown. Here you have to press the "b" key to carry on booting to “init 1”.

2.

Code:

sh-3.00# mount /dev/hda5 /mnt
Already mount

3.

Code:

sh-3.00# mkdir /home2 && cp -ar /mnt/* /home2/

4.

Code:

sh-3.00# umount /dev/hda5
(no printout)

5.You can use the fdisk in order to erase the partition (/dev/hda5) and to make 3 fresh partitions in the space left.

d - can be used to delete a partition
m - can be used to print the menu
n - can be used to add a new partition
q - can be used to quit without saving change
w - can be used to write table to disk and exit

Code:

sh-3.00# fdisk /dev/hda
Command (m for help): (type) d
Partition number (1-5): (type) 5

Command (m for help): (type) n
First cylinder (2691-4865, default 2691): press [Enter]
Using default value 2691

Last cylinder of +size or +sizeM or +sizeK (2691-4865, default 4865): (type) +10000M and press [Enter]

Command (m for help): (type) n and press [Enter]
First cylinder (3908-4865, default 390 : press [Enter]
Using default value 3908
Last cylinder of +size or +sizeM or +sizeK (3908-4865, default 4865): (type) +6000M and press [Enter]

Command (m for help): (type) n and press [Enter]
First cylinder (4638-4865, default 463 : press [Enter]
Using default value 4638
Last cylinder of +size or +sizeM or +sizeK (4638-4865, default 4865): press [Enter]

Command (m for help): (type) w and press [Enter]

Partition table has been altered!
Calling ioctl() to read partition table
Warning: Re-reading the partition table failed with error 16: Device and resource busy
The kernel still uses the old table
The new table will be used at the next reboot

6.
sh-3.00# (type) reboot and press [Enter]

FedoraCore3 gets rebooted automatically and then it shows the warning to run “fsck” for solving problems but you have to ignore it. Your PC is at present booted to “init 1”, the Single User Mode.

7. Continue

Code:

# mkfs -t ext3 /dev/hda5
# mkfs -t ext3 /dev/hda6
# mkfs -t ext3 /dev/hda7
(all no printout)

8.one more trap happened is that it seemed doubling every part of data back to /home but zero action taken.

Code:

# cp -ar /home2/* /home/

9.

Code:

# mkdir /mnt/lfs
# mkdir /mnt/livecd

10.

Code:

Edited /etc/fstab
# nano /etc/fstab
