Default gmirror array broken


One of my desktops was equiped with two hard drives I put into a mirror with gmirror at setup time. Today, I saw that my mirror is broken. I only have one consumer in my provier array:

% gmirror status                                                                                                                                                                             15:54

My other hard drive is ad10 and it doesn't look that broken...
% ls /dev/ad1                                                                                                                                                                                15:55
ad10%     ad10s1%   ad10s1a%  ad10s1b%  ad10s1c%  ad10s1d%  ad10s1e%  ad10s1f%  ad12%
How can I determine why my mirror broke and if my hard drive is broken?
