I have now done:
# mount -oremount,degraded /srv/tank
and tried again, but it produces the same response ("mount" now does
show "degraded" as one of the mount flags, however).
I have not yet tried completely unmounting it and mounting it again.

It is inconvenient to reboot just now, so if I'm able to fix things
without doing so (e.g. by balance or replace) then I would like to.
If that won't be possible then I will of course boot into a newer
kernel at the same time.
If I end up booting into 4.1.15 then it should be possible to mount
degraded and remove missing?
Cheers,
Andy
