You wouldn’t put ZFS on LVM, now would you?
BTFS is easy:
Install btrfs-progs and make sure kernel module is loaded…
mkfs.btrfs [-L <label of disk if wanted] /dev/ mount /dev/ tail -n1 /etc/mtab >> /etc/fstab]]>
I made the mistake of using gpt partition then putting btrfs on that and ouch lost my data later.
Now I make sure to wipe all the partitions from the drives first. Then I create my btrfs partitions.
This seems to work best starting with blank drives.
