I am using a Root-on-ZFS setup on a FreeBSD/arm 12-STABLE Raspberry Pi 2 system (as well as on arm64 on a Raspberry Pi 3):
# uname -rmp
12.1-STABLE arm armv7
It has two ZFS pools, one of which I use as a destination for various local backups:
# zpool list
NAME SIZE ALLOC FREE CKPOINT EXPANDSZ FRAG CAP DEDUP HEALTH ALTROOT
data 3.62T 778G 2.86T - - 0% 20% 1.00x ONLINE -
sys 7.50G 460M 7.05G - - 5% 5% 1.00x ONLINE -
I have vfs.zfs.arc_max="384M" set in /boot/loader.conf. The Pi 2 has 1 GB RAM.
The system has worked very well so far---it seems more stable than the UFS-based system it started out life as. I converted it using the writeup that Bernd Walter posted to freebsd-arm back in late February, 2019: https://lists.freebsd.org/pipermail/freebsd-arm/2019-February/019455.html
Scrubbing the "data" pool takes quite a while, though. The last one (completed on 2019-09-23) took 12 days 18:26:31. :-)
