The 2.5″ hdd failed in my Gen10.
To improve the reliability and simplicity of this solution i am going to run the operating system on the main RAID 10 array using a separate logical drive.
It was mentioned that this can be done on the Gen8 here
So lets try it out.
I will be loosing all data currently on the raid array by doing this, but i had backups so i am not concerned about that.
