So I just finished preclearing a 12 TB drive.  In my current setup I have dual parity drives both 4 TB.  I have 6 drives in my array of various sizes (4TB down to a 1 TB).  I want to install the new 12 TB as a parity drive and then replace  the 1 TB drive with one of the current 4TB parity drives.  

 

What is the recommended/safest way to do this?  My first thought was to stop array and unassign one of the parity drives and then assign the new 12 TB drive and let it rebuild parity...then once parity is rebuilt I could swap the 1 TB and 4 TB.   

 

or is this the procedure I should follow:  https://wiki.unraid.net/The_parity_swap_procedure

 

Would like confirmation before proceeding.

 

Thanks in advance,

Dan

That's the normal way, parity swap is for when you have a disabled data disk and a spare larger than parity, it could also be used for an upgrade, but array would be offline during the parity copy portion, so usually not much point.

Thank you!  

Proceeding now with the normal way.
