This means that you will be in trouble sooner or later.
Is there only sda1 on sda? If so, try
mdadm /dev/md0 --fail /dev/sda1
mdadm /dev/md0 --remove /dev/sda1
mdadm /dev/md0 --add /dev/sda1
which will end up overwriting the offline uncorrectable sectors. In most
cases this fixes the disk. But you will have to monitor it carefully
from now on.
