Question : submirror too small to attach

We replaced a disk and now when trying to attach the submirror to the mirror we get :  submirror too small to attach error...

There are two submirrors in this disk... one is supposed to be of 109M and the other of 136G.  I try to do the metattach and I am getting errors I believe it is because they are not the same size but do not know how to fix this...

Answer : submirror too small to attach

You need to make sure the size of the disks/slices to be mirrored are the same (at least the same amount of blocks ), please read the following pages:
