I am currently dual booting Ubuntu 18.04 with Windows 10. I would like to try ZFS. Is it possible to use ZFS when dual booting?
Yes, you can use ZFS on top of a partition just like other filesystems. When you create the zpool, just do:
zpool create <poolname> /dev/<path to partition>
I would not recommend creating multiple partitions, since it will not get you any particularly significant increase in redundancy if they’re all on the same disk.
