Just built a FreeNAS system over the past couple weeks and finished doing burn-in tests of my hard drives, wonder if I should wait and see how to install OpenZFS 2.0.0 before I create my storage config.



FreeNAS 12 (now named TrueNAS) is already using OpenZFS 2.0, or very nearly.


Does it support NFS4.2?(fallocate, sparse files and server side copy)


Aren't ZFS upgrades to existing vdevs really simple? I don't see any reason why you need to wait.


That’s the idea I’ve gotten when looking around online. I figured I was in the uncommon situation of having a completely blank and ready system, so I could afford to just wait a few days.


Yes, ZFS upgrades are really simple, but they are one-way, you can't downgrade after.


They certainly seem to be within OpenZFS over the past few years.
