[SOLVED] Raidz expansion

Hello there,

I have seen a couple of comments on Reddit & Github that raidz expansion is currently being developed/has already beta state.
Will that feature also work for PVE or do I still need all disks available at zpool create?
Currently you can only download the master branch, compile it and install it locally.
But please note: If you enable any features from a future version there is no possiblitiy to go back to a current stable version.
But be careful, RaidZ is not fast anyway and during an expansion the performance drops even more.
You should consider this carefully when planning.
