I've pointed to the information I need at least a dozen times before. In all probability a single disk didn't come back up, and it's more than possible that this error was recoverable, but not after you tried a newfs. Read the man page or http://www.vinumvm.org/vinum/how-to-debug.html and send me the info I ask for there.
