I recently rebuilt my FreeBSD 8.4 OS and rebooted, and when the system came back up, it refused to mount the zpool because: ZFS: unsupported ZFS version 5000 (should be 28) I didn't upgrade my zpool as far as I know. I tried booting off the latest 9.1 snapshot, but it also says that the zpool has a too-new version number and won't import it. I Google around and found a post about using gpart to update the boot code, which I tried with both the newest 8.4 release and also the newest 9.1 snapshot, just to make sure something wonky didn't happen with the disks. The good news is that I have relatively recent backups (yesterday evening) for this system, but I'm still totally confused as to what the heck happened. Is there some magic that I can type into a live boot CD to fix this problem without rebuilding the whole machine? -- Tim Gustafson tjg@ucsc.edu 831-459-5354 Baskin Engineering, Room 313A
