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:

1. Before you proceed with creating partitions, let's see the partitions that we need to create for our host computer:
   • Primary Partitions (ext4):
     • 30GB for / (i.e. "root")
     • 40GB for /home
     • 100GB for /var/lib/libvirt/images
   • 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)
   
   
2. We will now create the root (/) partition. Click on the add button (plus) sign.
   
3. In the Add a New Mount Point screen, select / as the mount-point (either by typing or selecting from drop-down menu), and enter 30720 in for partition size and click Add Mount Point button.
4. Repeat the same steps above for the /home partition and /var/lib/libvirt/images partition. You need to type the /var/lib/libvirt/images partition since it does not appear in the drop-down menu.
5. Select each of the created partitions, and make certain that the file-system type is changed from xfs to ext4.
6. Finally, add a swap partition (Mount Point: swap) for 16 GB.
