# This is NOT meant to be ran as a script, but an example how to setup a btrfs filesystem in debian/ubuntu

# Update to your real device, such as /dev/sdb1
# Run fdisk /dev/sdb to create an empty partition if you haven't already
device=/dev/zero

# Install btrfs pkg
apt-get -y install btrfs

# Make the partition
mkfs.btrfs -t btrfs ${device}

# Get the blkid
blkid ${device}

# Add the mount in your fstab like below:
# Replace the UUID below with the results of 'blkid' above
#UUID=YOUR_UUID_HERE     /media/zebra/   btrfs    ssd,noatime,ssd_spread,discard,compress=zlib    0       0
