2 failed drives with 2 parity drives

[Raki72]

Hi,

 

on my Unraid server two data drives were disabled due to an error. I have two parity drives and two spare drives. But I wonder how I can rebuild the two data drives most effectively.

 

Can I just put the two new drives in the system, add them to the Array and let Unraid do its magic with two disks in parallel at the same time.

 

Or do I have to sequentially add one new drive first, let Unraid rebuild the array. Then add the second drive, and let Unraid rebuild the array for the second drive.

 

Any sound idea is greatly appreicated. 😀

I would recommend posting the diagnostics first but if you just want to rebuild you can do both at the same time, make sure the emulated disks are mounting before starting.
