It's difficult to say from that information.  The man page gives a
number of hints about solving Vinum problems.  So does
http://www.vinumvm.org/vinum/how-to-debug.html.  In this case it would
be interesting to see what was in the log files.  On the face of it,
it looks as if a disk drive has died.  If not, there are tricks you
can use to recover them.  They're tricks because they bypass
consistency checking: part of your volume has died, and there's no way
to make it completely consistent again.
