So, I currently have two separate RAID 1 Volumes.
2x2TB Drives in Raid 1
2x4TB Drives in Raid 1.
I want to buy two 8TB wd reds and replace the 2tb drives.
Here’s where it gets interesting. I want to put the data from the 4TB’s on the 8TB drives, and the data from the 2TB drives on to the 4TB drives.
I don’t know the best course of action to accomplish that.
A few ideas i have are
Replace the 2’s with the 8’s, create the raid, transfer from the 4’s to the 8’s. clear then 4’s. then via a PC, transfer the contents off one of the pulled 2’s onto the now empty 4’s?
Pull a 2, put in an 8, populate the 8 with the contents of the 2, then replace the other 2 with an 8 and finish the mirroring. Somebody said this wasn’t possible? but i don’t know.
pull a 2, replace it with an 8. create a seperate (Third) volume, move files from 4 onto 8, then 2 to 4, then pull the remaining 2, pop another 8 in, then combine the two 8’s into a single Raid 1 volume? Not sure if possible.
a better idea i’m not aware of.
Any help would be greatly appreciated. Thank you.
