How to mount on boot an encrypted raid1?

Hi there;

I successfully made a raid1 and created /etc/mdadm.conf which make my raid1 available for my /etc/crypttab which also unlock itself during the boot but when I refer to the unlocked ext4 partition via /etc/fstab this one try to mount itself before mdadm and crypttab as done the job.

Is there a way I could make this happen ?
Maybe I miss option in my /etc/fstab for now it’s only:

/dev/mapper/crypt /mnt/crypt ext4 noexec,nodev 0 0
