[Nottingham] Assistance with ZFS

Looks like the snapshot are created by zfs-auto-snapshot. Assuming you want to get rid of old snapshots try this in a terminal:

sudo zfs-auto-snapshot --label=monthly --keep=3 //

This should create a new monthly snapshot and keep 2 most recent ones.

If it works and you are ok with having fewer monthly snapshots permanently then the parameter can be changed in a similar command in /etc/cron.monthly/zfs-auto-snapshot. (as a root of course)
Hope this helps.
Disclaimer: I don't use zfs but assume the logic is the same as with btrfs.
