Upgraded to 7. Had a drive show as unmountable. Stopped/started in maintenance mode and ran xfs file system fix tool. Took two attempts but claimed to have worked. Started the array normally. All data gone. Ok whatever I guess I'll rebuild that.
Then I took a look at shares. There are files all over the place. Things on array that should only be in pools and vice versa. Only about half of docker containers work. Rebooted unraid entirely with no improvement. And of course this latest windows problem makes sorting it out from another machine on the network a pain.
Think the unraid experiment is over.
