 +The output should look something like: 
 + 
 +  Personalities : [raid0]  
 +  md0 : active raid0 sdb[1] sdc[0] 
 +      209584128 blocks super 1.2 512k chunks 
 +   
 +  unused devices: <none> 
 + 
 +Next you have to create a filesystem to use your array 
 + 
 +  sudo mkfs.ext4 -F /dev/md0 
 + 
 +Note that MD0 is your array sdb1 and sdc2 together.  
 + 
 +Now create a mount point on your system like /mnt/md0 or /datastore 
 + 
 +   sudo mkdir -p /mnt/md0 
 + 
 +After that you are able to mount the new array 
 + 
 +   sudo mount /dev/md0 /mnt/md0 
 + 
 +Check if it is available by doing: 
 + 
 +  df -h -x devtmpfs -x tmpfs 
 + 
 +To make sure that the array is reassemble every time you boot your system you need to set your configuration of your array in a file /etc/mdadm/mdadm.conf. 
 + 
 +  sudo mdadm --detail --scan | sudo tee -a /etc/mdadm/mdadm.conf 
 + 
 +Next update the initramfs by doing a 
 + 
 +  sudo update-initramfs -u 
 + 
 +If you like to auto mount your array at boot you need a entry in your fstab. Edit your fstab like this 
 + 
 +  echo '/dev/md0 /mnt/md0 ext4 defaults,nofail,discard 0 0' | sudo tee -a /etc/fstab
  
  
 +That's all, enjoy.
