In all probability, your drive has failed and requires replacement. You'll see that from the system log file. Look at http://www.vinumvm.org/vinum/how-to-debug.html and http://www.vinumvm.org/vinum/replacing-drive.html. You don't need to submit the information if you can understand it and take the appropriate action.
