I don't know if it's written anywhere, but I always upgrade my bootloader before I do a zpool upgrade, just in case. If the loader doesn't know how to deal with an option it finds, it may bail which will require you to recover the system some other way (probably boot on some other media and upgrade your bootloader). When the OpenZFS stuff was installed, /usr/src/UPDATING mentioned issues (like not upgrading root pools until zstd was supported by the loader), so I'd be sure to track that for potential gotchas. I seem to recall that they yanked that warning out because it was wrong for UEFI systems (vs BIOS). _______________________________________________ freebsd-stable@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"
