Zstd gang

I made the mistake of not setting up encryption on my main 45TB zfs pool so I’m currently backing up everything on there to tape so I can recreate the pool (also need to change from mirrored to raidz) and then copying everything back to the drives. Although writing and reading each are around 6 days continuesly. Didn’t want to bite the bullet and pay more then I absolutely had to and only got a LTO-4 drive and tapes.

Wasn’t raidz expansion already in a tagged version or did I miss remember?
