Expand 2x1TB Raid 1 to 2x4TB Raid 1
I currently have 2x 1TB disks running in Raid1. The other two slots are running in Raid0, so all bays are full. I want to expand my Raid1 capacity to 4 TB, so I bought 2x 4TB disks. Can I just take...
So I found the solution and it's pretty easy. I just hot swapped a 1TB disk for a 4TB. Data will resync automatically. And then after repair of data I did the same thing again. After the second repair it showed 4TB of total capacity automatically. Great!

Please report back if this works. Maybe it's because I have a 12-bay legacy system converted to OS6 or because I didn't replace all the drives with larger ones, but I have not found a way to do that other than "under the hood" via SSH.

If it doesn't work, you'll need to back up the volume, destroy it, create a new one (recreating any shares), and then restore the files from the backup.
Or attempt to expand the volume with ssh.

If you end up going this way, see my post How-to-do-incremental-vertical-expansion-in-FlexRAID-mode . Though I wrote it for incremental expansion, it will work for a full volume expansion as well.
