Mirror setup? (Solved)

[kelt]

Hi all, I am currently doing a trial using the current stable version Unraid 6.9.2.

 

I am not sure if my understanding is correct in this setup:

2 x 2TB disks.

1 to parity and 1 as data disk.

 

Would this be the traditional mirror setup?

 

Supposedly if my data disk fails, I will shutdown the array, replace the disk and do a rebuild from parity?

Likewise if my parity disk fails, I will just replace the broken parity disk to be protected again?

 

Many thanks in advance!

In the special case of 2 drives they happen to be mirrors because of the way parity is calculated.   When you expand beyond 2 drives this is no longer true.   However the basic process then is still as you describe for a drive failure where you replace the broken drive and the system then rebuilds the parity/data drive to get you protected again.

Thank you all, it works as expected, simulate a disk fail and replaced my disk without any issues. All good!
