I also really hate that FreeNAS has no centralized management. Wish I could find a dev that would work with me for a stake in that sub-company I want to create just for BDR stuff. The system would be amazing if it had a nice webUI, but alas, I suck at writing PHP securely. I scripted the heck out of that machine for setting up and managing the ZFS, among checks and alerts for my root mdadm raid1, and setting up samba and a script to create users/share to the dataset.
To be honest, I setup a simple mdadm raid1 on the boot vols, and used ZoL on the dataset drives on a Ubuntu build and it worked flawlessly. I’d love if FreeNAS went with linux since it would be possible to use KVM as the hypervisor rather than bhyve – which has its I think I remember reading something about that root/boot ZoL setup and how to do it.
It really makes creating new VM’s from scratch extremely simple. ZFS is great when working with VMs – you can make a template VM (for example perform an Arch install (ZFS on root, dataset setup) and install all the base packages – networking, mirrors, zshell, WM or desktop, etc) and then its possible just clone zfs send/receive the datasets to new datasets to create a new VM. I’m not sure if its hacky stuff or not, however there was definitely a little bit of an art to setting up the ZFS stuff – way more involved as compared to a standard Ubuntu quick install from disk. In terms of boot/root ZFS, I’ve configured two ZFS on root systems with Arch Linux running in a VM on FreeNAS. The Linux systems – no Time Machine rebuild in either system for the last 4 months. The worst performer was FreeNAS share with SMB, followed by FreeNAS share with AFP. I’ve unfortunately had some problems with the Time Machine backups needing to be recreated. Test systems were FreeBSD jail on FreeNAS running AFP server, FreeBSD jail on FreeNAS with SMB share, Xcp-NG Arch Linux VM running AFP, XCP-NG Arch Linux VM running SMB. In terms of SMB, my only comparison was setting up a share to use with my Macs Time Machine. Kind of get where you are coming from with the FreeNAS arena - I have a 60TB unit and I love it – but it definitely has its quirks, and its far from a set it up, and walk away type of scenario.
