This testcase doesn't contain this information. Pass this test only after base testcase. It's contain all needed info. QA:Testcase_vzctl_base

Once your fresh Fedora 20 system is running, we will "move" /home to a bcache device. To do this it's convenient to have a minimum amount of data on /home. Do the following steps:

Setup

1. Open terminal
2. Switch to root user: su -
3. Install bcache tools: yum install bcache-tools

• If needed "backup" all data in /home to another place on your root filesystem:
  • comment /home out in your /etc/fstab
  • unmount /home (which is on /dev/sda2)
  • Make /dev/sda2 a bcache backing device: make-bcache -B /dev/sda2
  • Make /dev/sdb1 a bcache caching device: make-bcache -C /dev/sdb1
  • Note the set uuid and attach /dev/sdb1 to /dev/sda2: echo <set uuid> > /sys/block/bcache0/bcache/attach

How to test

Now you have a bcache device: /dev/bcache0

• use "bcache-status -s" to see details about your bcache device.
• create a filesystem: mkfs -t ext4 -L HOME /dev/bcache0
• create a /home entry in your /etc/fstab: LABEL=HOME /home ext4 defaults 1 2
• mount /home: mount -a
• If needed restore the /home backup you made earlier.

Now you have a system with /home on bcache.

Expected Results

• All steps completes without error
• reboot your system to see if it boots OK.
• do some other testing if you like. Limit the amount of data on /home or accept that it gets lost in the following steps.

Optional

In network tests I've used two IPs, em1 network interface. More details about them:

• 192.168.50.240 - free IP from my subnet
• 192.168.50.254 - default gw for my subnet
• em1 - name for ethernet interface
