I have a Pegasus R4 with 2 pairs of 3TB drives each in a RAID 1 mirror configuration. I thus have two separate volumes each of 3TB mounted on my desktop:
3TB Volume 1
- DISK 1 (3TB) & DISK 2 (3TB) in a RAID 1 configuration
3TB Volume 2
- DISK 3 (3TB) & DISK 4 (3TB) in a RAID 1 configuration
DISK2 has failed. The volume is still in tact and mounted, although I've since physically removed the dead drive from the slot. I want to take this opportunity to increase the volume size by replacing DISK1 & DISK 2 both with 4TB drives. However, I want to preserve the data in the process. Is that possible? This is what I'm hoping I can do:
1) Convert the current RAID 1 configured Volume 1 into a standalone drive (in other words, no RAID)
2) Insert a new 4TB drive into the defective drive slot
3) Create a new 4TB volume from the new 4TB drive
4) Mount the new 4TB drive and copy the contents from the existing 3TB volume to this new 4TB volume
5) Replace DISK1 with a new 4TB drive
6) Mirror DISK1 to DISK2 to create a new RAID1 volume and allow the rebuild/sync to complete
Is this even possible? Am I going about this the right way? What happens when I install the new 4TB DISK2? I don't want it to automatically re-build as a replacement for the failed 3TB DISK2. Wat's the correct way to do what I'm trying to do?
