Repartition hard drive Fedora Core 3 (FC3)

Recently I repartitioned the Hard Drive of a FC3 box. Steps taken as described hereinunder. Maybe the description can be used as tutorial. B.R. satimis --- Description --- Goal: to repartition existing Hard Drive, adding 3 new partitions, namely /home, /lfs and /livecd and each having size 10G, 6G and 1G respectively. /lfs (for building LinuxFromScratch using “Fedora Core 3” as host) /livecd (for building LiveCD from LinuxFromScratch) Operation System: Fedora Core 3 Bootloader: GRUB A. Preparation before repartition To find out the existing partitions   Code: # fdisk -l /dev/hda Disk /dev/hda: 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 13 104391 83 Linux /dev/hda2 14 2563 20482875 83 Linux /dev/hda3 2564 2690 1020127+ 82 Linux swap /dev/hda4 2691 4865 17470687+ 5 Extended /dev/hda5 2691 4865 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 20G 3.7G 15G 20% / /dev/hda1 ext3 99M 14M 80M 15% /boot none tmpfs 125M 0 125M 0% /dev/shm /dev/hda5 ext3 17G 1.5G 15G 10% /home B. Repartition Steps 1. Boot into “init 1”, Single User Mode During booting – on Bootloader window 1.1. Select the most recent kernel (using the “UP and “DOWN” arrows) 1.2. Press the "e" key to edit the commands for that kernel before booting 1.3. On next screen, choose the line mentioning "kernel /vmlinuz.........." and press "e" key again (also using the “UP and “DOWN” arrows) 1.4. On next screen, at the END of the line of "grub edit > kernel /vmlinuz..." hit space bar once to get a space before typing and type "init 1" without the (quotation marks) and then press "Enter" key. 1.5. Now coming back to previous screen and a line with "init 1" indicated at its end will appear. Press the "b" key to continue booting to “init 1” (text mode) 2. sh-3.00# mount /dev/hda5 /mnt Already mount (This may not be true, please see steps 8. below) 3. sh-3.00# mkdir /home2 && cp -ar /mnt/* /home2/ 4. sh-3.00# umount /dev/hda5 (no printout) 5. Used fdisk to delete the partition (/dev/hda5) and to create 3 new partitions in the space left. Remark: d = delete a partition m = print the menu n = add a new partition q = quit without saving change w = write table to disk and exit 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 Syncing disk 6. sh-3.00# (type) reboot and press [Enter] FedoraCore3 rebooted automatically. Finally it came to warning screen suggesting to run “fsck” to fix problems. Remark: Ignore it. Don't take any action. The trick is here. The PC is now already booted to “init 1”, the Single User Mode. 7. Continue # mkfs -t ext3 /dev/hda5 # mkfs -t ext3 /dev/hda6 # mkfs -t ext3 /dev/hda7 (all no printout) 8. # cp -ar /home2/* /home/ Another trick happened here. It seemed copying all data back to /home but nothing actioned. The Hard Drive was working with the pilot light on. 9. # mkdir /mnt/lfs # mkdir /mnt/livecd 10. Edited /etc/fstab # nano /etc/fstab Original /etc/fstab before editing;   Code: # cat /etc/fstab # This file is edited by fstab-sync - see 'man fstab-sync' for details LABEL=/ / ext3 defaults 1 1 LABEL=/boot /boot ext3 defaults 1 2 none /dev/pts devpts gid=5,mode=620 0 0 none /dev/shm tmpfs defaults 0 0 LABEL=/home /home ext3 defaults 1 2 none /proc proc defaults 0 0 none /sys sysfs defaults 0 0 /dev/hda3 swap swap defaults 0 0 /dev/hdd /media/cdrom auto pamconsole,exec,noauto,fscontext=system_u:object_r:removable_t,managed 0 0 /dev/hdc /media/cdrecorder auto pamconsole,exec,noauto,fscontext=system_u:object_r:removable_t,managed 0 0 /dev/fd0 /media/floppy auto pamconsole,exec,noauto,fscontext=system_u:object_r:removable_t,managed 0 0 Changed   Code: LABEL=/home /home ext3 defaults 1 2 to   Code: /dev/hda5 /home ext3 defaults 1 2 Added:   Code: /dev/hda6 /mnt/lfs ext3 defaults 1 2 /dev/hda7 /mnt/livecd ext3 defaults 1 2 /etc/fstab after editing;   Code: # This file is edited by fstab-sync - see 'man fstab-sync' for details LABEL=/ / ext3 defaults 1 1 LABEL=/boot /boot ext3 defaults 1 2 none /dev/pts devpts gid=5,mode=620 0 0 none /dev/shm tmpfs defaults 0 0 /dev/hda5 /home ext3 defaults 1 2 none /proc proc defaults 0 0 none /sys sysfs defaults 0 0 /dev/hda3 swap swap defaults 0 0 /dev/hda6 /mnt/lfs ext3 defaults 1 2 /dev/hda7 /mnt/livecd ext3 defaults 1 2 /dev/hdd /media/cdrom auto pamconsole,exec,noauto,fscontext=system_u:object_r:removable_t,managed 0 0 /dev/hdc /media/cdrecorder auto pamconsole,exec,noauto,fscontext=system_u:object_r:removable_t,managed 0 0 /dev/fd0 /media/floppy auto pamconsole,exec,noauto,fscontext=system_u:object_r:removable_t,managed 0 0 11. # reboot Rebooted PC again PC rebooted without problem to Login screen. I was not allowed to login as user, saying /home/user/ not found. But I was allowed to login as Root. 12. After login as Root I discovered /home being empty. Started Kconsole # cp -ar /home2/* /home/ Logout and relogin. This time I was allowed to login as “user” Remark: 1)Using /lfs and /mnt/lfs is only following the LFS instruction 2)Better using -v flag to replace -r flag cp -av /home2/* /home/ to copy all data back
