I was successfully running 2TB Raid 1 - Mirroring in Bays 1 and 2 with Bays 3 and 4 empty.
I loaded bays 3 and 4 with 2TB drives and launched the Migrate selecting drives 3 and 4
The log shows "Mirror Disk Volume: Drive 1 2] Do RAID Migration" and the system ran for hours doing migration
I have ended up with the following indication on the Raid Management Page:
"Mirroring Disk Volume: Drive 2 1832.31 GB Bitmap = Yes In degraded mode Please insert a drive of larger capacity and wait for the drive status to become Ready before executing this operation."
OK I am confused? Any wisdom out there to help.
Drives 3 and 4 show as unmounted though they are in the bays and formatted.
Do I need to Mirror 3 and 4 as Raid 1 first for Raid 10 to work?
