I have a new FreeNAS box that I just built and have been running in a test environment. Last night I upgraded from 8.0.1 release to 8.0.2 and afterwards, I have an alert and my ZFS volume is hosed up. I have a 5 drive, 7.1TB volume setup that had about 500GB of data on it (all replicated elsewhere for now). The attached image shows my error (sorry for the tiny size of the image). I'm new to FreeNAS and have very little BSD experience, so I'm not sure what to do to resolve this.
