Lab Exercise #7: Setting up an alternate filesystem (/home).
Scenario: /home is full you need to allocate a new filesystem to accommodate more user space
Review TAR command (Chapter 5)
1) Run grub2-install /dev/sda to reinstall Fedora MBR (See recovery notes)
2) Remove Ubuntu partitions via fdisk
3) Review DMESG messages to see devices
4) Display filesystems with du, df –v, mount
5) Add diskquotas for remaining users. How?
6) Add quotaon to system startup . How?
7) Place system into single user or maintenance mode
8) Run fdisk –l to display the hardrive layout
9) Allocate a partition twice the size of current /home allocation (? To view menu).
fdisk /dev/sda
m
n
accept default starting cylinder
+xxxxM …. Where xxxx is twice the size of the current /home directory
p ….. to show results
w to write to disk
10) Reboot? Seee messages.
11) Make a new filesystem: mkfs –t ext3 /dev/sdax … x is new partition #
Pay attention to messages
12) make a temporary home directory /mnt/hometmp
13) mount the new filesystem under /mnt/hometmp
14) Copy the contents of /home to /mnt/hometmp using commands:
cd /home
cp –rp * /mnt/hometmp
What do the copy command flags do?
15) Change /etc/fstab to mount /home on the new filesystem and /mnt/hometmp on the old file system
16) Reboot
17) Mount old /home partition to /mnt/hometmp
18) Backup /mnt/hometmp directory using TAR
19) Restore it to /home
20) Backup current /home directory using TAR and GZIP and restore it to /mnt/hometmp
Related commands: cp, du, df, fdisk, mkfs, mount, umount,

Lab Exercise 8: Using TAR and ZIP, other file systems
Make sure you complete LAB 7
1) umount /mnt/hometmp
2) use fdisk /dev/sda to change the old /home partition type from Lab 7 to Fat32
fdisk /dev/sda
m
t
x …. x is old /home partition
l …. list partition types
b …. set partition type to WIN 95 FAT32
p …. to show results
w …. to write to disk
3) Reformat the old /home partition as MSDOS filesystem and call it /share
mkfs –t vfat /dev/sdax … x is old /home partition
Pay attention to messages
4) Backup /home using TAR and GZIP and restore it to /share. Compare results to /home using ls –al.
Related commands: mkdev, mkfs, df, fdisk, du, mount
