Hi, Peter. I have not used a ZFS pool for audio work, but I used to work in the ZFS group at Oracle. RAIDZ2 optimizes your available space at the price of performance. If I was going to record multiple tracks in a DAW to a ZFS pool, I'd be using a mirrored pool. The ZFS RAID levels are designed to spread the load around, and bog down with a small number of drives. Given that this is a local pool we're talking about, we're likely talking about 4 or 5 drives in the pool at best. You might be OK given that the pool is dedicated to the machine, but I'd test it thoroughly. I'd avoid RAIDZ1 - there's insufficient redundancy and has led to occasional data loss. Depending on the devices, you might be OK - a pool of SSDs will be better than a pool of spinning drives, for example. If you only ever record a max of 2 tracks at a time, you'll also likely be fine. This is based on my experiences with big loads on a ZFS storage appliance; you may have a very different experience with the local pool under Linux.
