How do you "reset the array configuration and rebuild parity instead"?? [SOLVED]

Hello,

    I have had an issue with my unRAID installation, so I installed a new installation of unRAID on a new USB. Before this issue i had three disks installed 2 of which were data, and i know all the information on them is ok. However now that i have booted the machine up again, it is seeing the 2nd data disk as a new disk, and therefore wants to format it, WHICH I DONT WANT TO DO.

    In the descirption when you are about to take the disks online it says:

If you want to preserve the data on the new disk(s), reset the array configuration and rebuild parity instead.

    How do you do this so that the data on the two data disks are kept and the parity is rebuild instead of formatting the 2 data disks?

SYSTEM:

    Version:  5 beta 14 - Clean installation.

There is a button on the Utils tab in the management interface to set a new configuration. 

Is it the same as doing this?

I followed the steps that you said. to stop erase the parity, however not it is claiming that one of the data disks is "unformatted". Is there anything that i can do now? Screenshot attached.

It is now claiming that it does not know the "File System Type" of the HDD.

Sorted. Issue has been resolved.

Is it the same as doing this?

Additionally, that procedure does NOT work in the later 5.X series if you refresh the management page in unRAID in any way.
