I suggest creating one virtual disk for the VM system drive and installing FreeBSD there. Once FreeBSD is up and running, create additional virtual disks for ZFS experiments -- creating pools, creating filesystems and volumes, taking snapshots of datasets, rolling back datasets from snapshots, creating clones, replication, simulated disasters and recovery, etc.. > Also the only guides that are offical are the handbook, New and old and > other guides i found. > > 1. https://docs.freebsd.org/en/books/handbook/zfs/ > > 2, https://is.gd/GGTjK8 > > 3. https://somedudesays.com/2021/08/the-basic-guide-to-working-with-zfs/ > > 4. https://wiki.debian.org/ZFS > > 5. https://wiki.gentoo.org/wiki/ZFS > > 6. https://wiki.archlinux.org/title/ZFS > > Don't know if we are suppose to post links that aren't part of freeBSD > here but i'm learning everyday if we can't just tell me so i know in the > future. > > What do you guys recommend?
