No objects where found beyond the two drives. See below for the full log.

These are the only relevant lines I could find in my /var/log/all.log:

Feb 13 13:06:13 pcwin002 kernel: /dev/vinum/stor: clean, 787640 free (776 frags, 98358 blocks, 0.0% fragmentation)
Feb 13 13:32:23 pcwin002 kernel: Can't stat /dev/vinum/stor: No such file or directory

The first is from the old kernel and in-between I booted the new kernel.

See below.

Would I lose my data if I recreated the configuration file? (just an idea).
