Lab 1 Warnings / Debrief

Preparing for Lab 1

Thinking Ahead

Bring Required Materials to Class

Come prepared for labs:

• Removable SATA Drive ( min 250 GB )
• USB Stick ( min 8 GB )
• CENTOS 7 Full INSTALL DVD
• Lab 1 Logbook (Instructor can't sign-off lab without seeing lab-book notes)
• Access to Lab Instructions: printout, notebook, netbook, smartphone

Notes / Warnings

• Failure to properly following lab instructions may result in re-doing lab again!

• Hard Disk partitions are simply smaller logical storage units (containers) within a hard disk

• Advantages of Hard Disk Partitions

• Separation of operating system files from data (easier recovery)
• Allows for booting multiple operating systems
• Separation of Data for efficient access and sharing

• Make certain to create the correct partitions (Have instructor or lab monitor confirm before proceeding with install):

Primary Partitions (ext4):

• 30GB for / (i.e. "root")
• 40GB for /home
• 100GB for /var/lib/libvirt/images (need to manually enter this "mount-point")

Swap Partition:

• 16GB (Note: "swap" must be selected from the drop down menu)

NOTE: Remember that the sizes are recorded in MB (eg. 30 GB = 30000 MB) and you should multiply GB by a factor of 1024 to get the correct size.
(eg. 30 GB x 1024 = 30720 MB)

Preparing for Lab Sign-Off

Students should be prepared with all required commands (system information) displayed in a terminal (or multiple terminals) prior to calling the instructor for signoff.

In order to properly complete your lab and move to the next lab, you must have your instructor "sign-off" on your lab

• Each "signed-off" lab (before due date) is worth 1% of your final grade.
• Signing-off on labs help to spot errors that can cause problems with future labs.
• Do you ask the instructor what to check for! Read at the bottom of the lab the requirements, and have all proof available for instructor to view at same time.
• Failing to be prepared and asking instructor what to check when assignment is mark will result in deduct of marks!
• For example, open multiple terminals with command results. If properly set-up ahead of sign-off, the process should only take instructor approx 20 seconds to sign-off your lab.
• If you do not have your lab-logbook, you MUST show your work and your lab log-book to your instructor for sign-off in the next class. This may cause a late penalty if past the required due date.
