- Concepts/Commands learned/used in this week's lecture
- File System: A way to organize data for efficient and easy access
- Containers: Objects (partitions, files, volumes) that hold file systems
- Virtual File System: Allows transparent access to files on different file systems
- 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
- Linux Boot Process
