I'm just waiting on parts to arrive for my unRAID build and i'm trying to figure out the best way to move my data from my existing RAID5 NAS.
Currently I have a Thecus N5550 NAS 4x3TB WD RED in RAID5.
The critical data is a much smaller amount and I have a few backups of and will transfer later when the array is fully setup. I have about ~6.5TB in use of non-critical media (no backups, but i'm willing to risk the loss of these).
I bought a 4TB RED to use a parity in the new unRAID config and want to reuse my 4x3TB from the NAS. I also have 2x1TB and 1x1.5TB older green drives I planned to use to make the transition.
My plan i'm looking for suggestions/feedback on:
[*]Put new 4TB drive in existing NAS and copy files . Repeat for Green drives until I have a copy of all data from existing NAS (what should I format these drives as, does it matter?)
[*]Remove the 4x3TB RAID5 and create unRAID data array (no parity)
[*]Insert other drives and Copy data (unassigned devices plugin?) to array
[*]Once complete reformat/add 4TB drive as parity to the array. (possibly green drives as data to the array)
Any thoughts? I understand that i'm at risk during this time but as I said i'm willing to take that risk rather than purchase more drives at this time.
