  • Linux file systems support UUIDs, Windows not so much
  • Commands: blkid, vol_id, uuidgen, tune2fs, findfs
• Working with Logical Volumes (LVM)
  • Physical Volumes (eg partitions) are joined into Volume Groups
  • Logical Volumes are drawn from Volume Groups
  • Commands: pvcreate, vgcreate, lvcreate

Week 3 (Sept 15) - Linux Startup

• Activities for this week
  • Complete the SYA710 Lab02 and blog about the experience.
  • Lab02 is due before midnight Wednesday, September 24, 2008
• Concepts/Commands learned/used in this week's lecture
  • Linux Boot Process
    • Power on - Code in ROM BIOS finds and loads 1st stage loader from boot device (MBR)
    • 1st stage loader finds and loads 2nd stage loader (GRUB)
    • 2nd stage loader finds and loads Linux kernel and initial ram disk
    • kernel checks the system hardware, mounts the root device and loads the needed kernel modules
    • kernel runs init program (PID=1)
  • Init Process (System V)
    • init reads /etc/inittab to get default run level
    • init runs rc
    • rc runs runlevel scripts
  • Init Process (Upstart)
    • init gets jobs/tasks from /etc/events.d/
    • init emits startup event to start system
    • init waits for more events
    • fully compatible with System V

How to boot up Fedora 9 from /dev/sdb in room T2107

These instructions assume that Fedora 9 has been installed on /dev/sdb with the following partition setup:
/dev/sdb1 = /boot
/dev/sdb2 = /
/dev/sdb3 = swap
/dev/sdb4 = extended
/dev/sdb5 = /home

Boot up the system and when the data recovery card displays a menu of OS choices, choose Fedora 8. A boot screen will be displayed with a 3 second countdown before booting. Press the <ESC> key before the countdown reaches 0. Another menu is displayed listing two Fedora 8 kernels to boot from:

• Fedora (2.6.24.5-85.fc8)
• Fedora (2.6.24.4-64.fc8)

Do not choose either of these. Instead press the "c" key to display a command line. Issue the following commands:

root (hd1,0)
kernel /vmlinuz-2.6.26.5-45.fc9.i686 root=/dev/sdb2
initrd /initrd-2.6.26.5-45.fc9.i686.img
boot

Fedora 9 will now boot.

OR - another way

root (hd1,1)
kernel (hd1,0)/vmlinuz-2.6.26.5-45.fc9.i686
initrd (hd1,0)/initrd-2.6.26.5-45.fc9.i686.img
boot
