To add to what Matthew said: if FreeBSD uses a more recent version of zpool, and you run `zpool upgrade` on FreeBSD, I presume that would be a point of no return. And while I can't say for certain--since I've never tried it--actively sharing a single zpool between two operating systems might be a bit of a pain. You'd need to export the pool from one system and then import it to the other on every boot, no? In short, permanently moving a pool from Linux to FreeBSD shouldn't be any hassle. Moving in the other direction, however... -- ================================================================= :: Brandon Wandersee :: :: brandon.wandersee@gmail.com :: ==================================================================
