I had a similar problem a bit ago where suddenly my drives were too small, causing the UNAVAIL corrupted-data problem. I managed to fix it by using gconcat to stitch an extra MB of space from the boot drive onto it. Not a very good solution, but the best I found until FreeBSD gets shrink support (which sadly seems like it may be a long while) Failing that, you could use OpenSolaris to import it (as it does have minimal support for opening mismatched sized vdevs), copy the data off, destroy, and restore.
