OK, a bit more progress...
It appears that the uptime was >20 days which means I didn't reboot it when I thought I had. I just rebooted it and the array is back.
syslog shows errors like those above as far back as it goes (7 days) so I can't see what caused it - I haven't been using the array so wouldn't have noticed it fail. I'll have to monitor it and see.
