I was having issues keeping the system running. So turned the system off, and ran a memory test, and replaced memory. When I rebooted the pool is unknown, and this is in the log file. Could booting from a CD and Running a memory test mess with the Headers on each drive???? How is that possible.
I have attached the log file, and yes I know there are some bad sectors on ada3 but it has been that way since I built it and has worked fine for over 11 months.
