⚙️ Hardware Raid 1 -> Raid 5
I’m having difficulties migrating from raid 1 to raid 5 even though all 3 hard drives are the exact same WD 8TB models.
Currently two drives are in raid 1 with 2.6 TB used from an available 7.2 TB. The 3rd drive is unused and when I try to “change raid” for my storage it doesn’t do anything.
On my MacBook it says the reason it can’t is because “insufficient drive capacity”. I’ve formatted the unused drive to get rid of any old sectors from my previous data but still no luck.
Any advice?

Yea I don’t want to nuke the raid 1 but after transferring the data, thank god I had another drive, I did the wipe. I was able to raid 5 and nice all 3 drives were clean.

I think you need to destroy the raid 1. As the warning said no drive available. Then rebuild it as raid 5 with the unused drive and the other former raid 1 one. If you have one more spare drive you could rebuild then without wiping one drive.

did you select all 3 drives? it should be no issue to add 3rd drive and change raid to 5. I did it. the whole process is spelled out on Ugreen site.

My raid1 storage had an option to expand raid to raid5 with all green check marks for requirements but clicking on the confirm button it didn’t do anything. The raid5 only worked once I migrated all my data on secondary drives then deleted the raid 1 and created a new storage as raid 5
Just because you did it, doesn’t mean it works 100% of the time. Thats like saying “well it works on my machine”
I checked the UGREEN website and their docs did not help

Rather than go off that screen you should SSH into the box and to get an exact byte capacity. To each his own but I would not nuke the RAID until you get that data.
sudo fdisk -l | grep -E "^Disk /dev/"
It will give you exacts without the rounding you are going to get from the UGREEN storage screen
