  • Commands: mkfs, fsck, fdisk, mount, umount, e2label, resize2fs
• Using UUIDs (universally unique identifiers)
  • 128-bit numbers make hard disk management easier
  • add UUID= entry in /etc/fstab
  • 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
