[SOLVED] Converted ext4 to btrfs, systemd-remount-fs failing at boot

I changed the UUID in fstab but I'm still getting the following service failure

$ systemctl status systemd-remount-fs.service

● systemd-remount-fs.service - Remount Root and Kernel File Systems

Here's my fstab: 
 

# /dev/mapper/root
UUID=cf4b8834-3581-448f-b1e8-d2334359c16b       /               btrfs           rw,relatime,data=ordered        0 0

# /dev/sda1
UUID=12636bd2-5d5b-4267-843f-b1bbc130e62c       /boot           ext4            rw,relatime,stripe=4,data=ordered       0 2

EDIT:

Solved by removing 'data=ordered' from /etc/fstab. Derp.

Here's a riddle for you, straight from my dmesg!

btrfs: unrecognized mount option 'data=ordered'

Re: [SOLVED] Converted ext4 to btrfs, systemd-remount-fs failing at boot

data=ordered is an ext# mount option used to specify the journaling mode. It doesn't make any sense to use it for a btrfs partition.
