I'm looking to expand the capacity of my qnap NAS by tripling the drive size from 2TBx8 to 6TBx8. However, I'm afraid the raid 5 will die before I can rebuild the array 8 times!!
Can I remove and clone each disk independantly and add them back to the raid?
My only other option is to buy a new NAS and maybe sell the old one after migrating the data.
I know zfs could do this, but I have no idea what qnap does in the background.
As a POC, I may just try 1 disk and see what happens, outage is not a concern do it can be offline for a week without issue.
