September 18, 20214 yr Hey, Kinda new to Unraid. I got my server setup and moved all my data from my old FreeNas which was a RAID-Z2 with 2 pools of 6, so it was 4 drives as parity which was a waste and main reason I switched. Had limited space so I had to use one of the drives for data that I wanted to use as Parity. My current setup: 14TB - Parity 14TB - Data ----> I want to make this second Parity 10TB - Data 10TB - Data 8TB - Data I already moved all the data off the 2nd 14TB. Do I stop the array and remove that drive then start it back? After it builds parity I stop it again and then add that drive as 2nd Parity and start it again?
September 18, 20214 yr Community Expert You will have to New Config without that disk then rebuild parity. You can build both parity at the same time.
September 18, 20214 yr Author If I do a new config it will not wipe out the other disks correct? So if im understanding, I would do the following: 1. Stop the array 2. Change the 2nd 14TB to Parity 3. Go to Tools > New Config 4. Enable Preserve current assignments 5. Start the Array Thanks again Currently I have shares on different drives. So like Drives 2 to 4 are for TV Shows, Disk 8-9 is Movies, Disk 7 Anime. I also created a cache pool for Docker apps (Sonarr, Radarr, etc) Since it is a new config I will have to go back and resign the drives for the Shares?

Step 2 has to be done after step 4. the system will remember any share settings so you only need to make changes for cases where you want different settings.
September 19, 20214 yr Author Thanks, Just a little nervous as I cannibalized my other build so everything is on this. Dont want to lose any of the data already on the disks so using the 'New Config' sounded like it would drop everything. Im still finishing up some transfer which is going super slow sometimes from the 14TB to the new disks (ranges from 30MB/sec up to 60MB/sec. Ill give it a try. Thanks

I use a Synology, Google One and Blurays for my real data.
September 20, 20214 yr Author Thanks again. It worked, its rebuilding parity now. So hopefully in a day I can start messing around with the apps.
