4 soft array plate for 10, simulate the hard disk is missing, is the operating system can't identify directly, should be how to restore,

Searched a lot, it is bad to arrays that piece of plate
For mdadm -f
Then
For mdadm - r
Add new dish can be restored,


But if I want to try this dish are not directly in the system to identify how, you can't manually - f and remove the disk from the RAID out, how should operate,

Another test I found built RAID10, shut down, to take off one piece of plate, array error, turned into the system to check the information into a raid 0 array



And view the information of the single disk still RAID10.
