Replace all drives and change RAID

Post by mwarney »

I have a Terramaster F4-210 currently set up as RAID 1 (mirror) using two 6TB Ironwolf drives. I want to replace the two 6 TB drives with four 4 TB drives and convert to RAID 5. There IS currently data stored on the system. Could someone please outline the steps I would take?
Thanks

it seems this is not possible, you just can not replace your drive which is already configured in a RAID with a smaller size new drive. you have to back up your data, delete the current RAID 1, and rebuild a new RAID 5 with your 4TB drives.
To contact our team, please send email to following addresses, remember to replace (at) with @:

Thanks... I was afraid of that. What if I added two more 6 TB drives and then converted to RAID 5?
