Hi all,
I have an MSA 2040 with 4 x 4TB drives in a RAID 5 array.
I've got 3 more identical disks to go in it and I need to add more storage but I also want to improve resilience.
I believe that I can do this by adding 2 more drives for storage and using the third as an extra parity disk in RAID 6.
The question is, can I do this on the fly without toasting the data on the existing RAID 5 array?
Thanks
