Failed disk, preclear, unclean shoutdown

[skler]

I have two disk failed (maybe for an electrical problem), in an array with two parity disks.

 

What I did is:

1. Stop the array.

2. I had to restart the server, because was unresponsive,

3. I've removed the disk from the array

4. I did a pre-clear of the two disks, the cleaning was successful 

 

Now I can re-add the disk into the array. 

 

What I want to archive is to use the parity disks to rebuild this two disks.

 

What I have to do? Just re-add them?

If the emulated disks are mounting and contents look correct you can do a standard rebuild:

If I start the array while I have this message:

 

"Stopped. Unclean shutdown detected." 

 

The parity will be rebuild or disk will be emulated from parity disks?

If there are two disabled disks, parity cannot be rebuilt, it will just do a read check, you can abort that.
