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:
# Open terminal
# Switch to root user: <code>su -</code>
# Install bcache tools: <code>yum install bcache-tools</code>
* 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
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.
* 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.
In network tests I've used two IPs, em1 network interface. More details about them:
* - free IP from my subnet
* - default gw for my subnet
* em1 - name for ethernet interface
