Why x86? Is OMV only x86 right now?
I like ZFS, but also like BTRFS. Also like how BTRFS is built in and maintained.
Where as ZFS requires changing kernel and plugin and other maintenance factors.
I'm also a bit worried about upgradeability when using ZFS especially as plugins.
Feel like the direction and support is heading towards better BTRFS (which I used in synology and currently use in unRAID) so I'd rather not have to copy all my data off and rebuild again in 2/3 years.
