zfs discuss - Oct 2010 - Upgrade a degraded pool

I know that this is not necessarily the right forum, but the FreeBSD forum
haven''t been able to help me...

I recently updated my FreeBSD 8.0 RC3 to 8.1 and after the update I
can''t import my zpool. My computer says that no such pool exists, even
though it can be seen with the zpool status command. I assume that it''s
due to different zfs versions. That should be solved by a zpool upgrade, BUT the
problem is that I also have a failed disk. What happens to my data if I upgrade
a degraded pool? Furthermore a disk label was lost and zfs tried to replace the
disk, with a disk which won''t be available once I get the disk
re-labeled. I have no clues about what to do... :s

I only use the computer as a home file server, so I could migrate to OpenSolaris
if that would help my case...

Any help would be most appreciated!!!
