Did you ever use ZFS?
I want to build a linux-setup with some cool new stuff I didn't use so far and ZFS is among them.

On FreeBSD ZFS was quite acceptable.

Currently working on setting up Void Linux on ZFS on LVM on LUKS. Work in progress due to RL interference…

I'm sure it works great. I'm using nilfs and I'm really happy with it.

Works pretty great. I've also had to change OS a few times, and exporting/importing a zfs pool is incredibly easy

FreeNAS can help make the setup and management of a storage server a bit easier

My FreeBSD home server uses ZFS. I did have to read the docs a lot because both FreeBSD and ZFS were new to be. And now it just works.
My data is mirrored on two HDDs. I haven't used the other advanced features (snapshots, cloning, ...) so far.

@Condor didn't you know some about this?

@linuxxx ZFS on the servers, btrfs on the workstations.. works great! 😁
