Well I have ZFS up and running from Git - it has become surprisingly easy over the years. BTW, from the archive, I see you were intent on RAIDZ. I love RAIDZ, but after running the raidz benchmark, I strongly advise against anything but mirrors on a T5120 :-( The parity algorithms are really slow on that CPU. And looking at the VIS(1+2) instruction set, I doubt they can be significantly accelerated (VIS is old and lacks the required 8 bits operations, it doesn't even get any kind of shifts before VIS3). Unless we can somehow leverage the cryptographic stuff (the Modular Arithmetic Unit, MUA) ? But I don't see any documentation beyond "go through the Solaris driver" :-( Anyway for the new Debian I'm combining this page <https://github.com/zfsonlinux/zfs/wiki/Debian-Stretch-Root-on-ZFS> and this ML with this: sudo debootstrap --no-check-gpg sid /mnt http://ftp.ports.debian.org/debian-ports /mnt is where the ZFS root is mounted (didn't do anywhere near as many FS as the wiki suggests). ZFS is on /dev/sdd2, with /dev/sdd1 a "boot partition" similar to the one debian-installer added on /dev/sdc, as it is apparently required. Cordially, -- Romain Dolbeau
