Are there any practical limitations to just using a ZFS pool created on Linux? Technically no, but I would boot a FreeBSD live CD first and import / attach the pool. Generally, ZFS on Linux is typically a few feature flags behind FreeBSD, so there shouldn't be any issues with doing this. > > If there’s reasonable doubt of issues I'll just rebuilt the pools under FreeBSD, but would be great if I didn't need to do that. It'd be cool if it’s just a # zpool upgrade away hah :) That should do the trick, but bear in mind it will be hard (read: impossible) to go the other way once upgraded.
