How to stop ZFS?

Question

So during installation, I decided to try out ZFS. Initially it looked good, but it is taking up way too much space on my 60 GB SSD. How do I stop snapshots and delete existing ones? I am using ubuntu 20.04 and I am new to the linux world (migrating from windows)

Answer 1

To list snapshots:

zfs list -t snapshot

To delete snapshots:

zfs destroy pool/fs@snapshot

which you got from the first command.

Answer 2

To completely stop snapshoting you need to clear com.sun:auto-snapshot property

sudo zfs set com.sun:auto-snapshot=false tank/backup

Actually, it makes sense to tune other snapshot related properties. See my answer to another snapshot related question.
