I get those messages on v28 pools, made with ZFS for Linux or FreeBSD or older versions of FreeNAS. I'm hesitant to move beyond v28, even though I'd like some of the newer features, because I am not clear on the compatibility matrix among non-Oracle ZFS implementations. Version 28 seems to be the last version that all extant ZFS implementations can read. I'd be very willing to give up Oracle compatibility but don't want to lock myself out of moving between ZFS on Linux and *BSD. If anyone else has thoughts or experience to share here, that'd be mist welcome!
