I have a FreeBSD guest running under VirtualBox 3.1.2 on Mac OS X. It's = running a recent 8-STABLE and is a ZFS-only install booting via = gptzfsboot. I use this VirtualBox guest as a test install. A day or so ago I noticed "zpool status" report that my pool could be = upgraded from v13 to v14. I did this, via "zfs upgrade -a". Today, when attempting to fire up this FreeBSD guest in VirtualBox I get = this on the console: =3D=3D=3D=3D=3D ZFS: unsupported ZFS version 14 (should be 13) No ZFS pools located, can't boot _ =3D=3D=3D=3D=3D and the boot halts at that point. I don't see the boot menu I normally = see that lists the opportunity to boot single-user; disable ACPI; and so = on. Has anyone else experienced this? Is this a mismatch between gptzfsboot = and my current pool version? (Gptzfsboot includes the message I'm = seeing.) Am I supposed to rebuild and replace gptzfsboot every time the = pool version is updated? (There was no advisory in /usr/src/UPDATING = concerning this, nor do I remember seeing it elsewhere.) Now I have to figure out how to dig out from this. Well, I guess that's = what test installations are for... :-) Cheers, Paul.=
