I have a ReadyNAS 1100, with 4X1.5TB disks.

Due to some problems, I am thinking to do the following:

  • Take the 4 HD's out (4X1.5TB identical disks, keep the order)
  • Put new 4 Disks in (4X500GB identical disks, smaller disks - still identical)
  • Restore to factory default
  • Once NAS is working properly take the 4 disks out
  • Put the original 4X1.5TB disks in the correct order.

Do you think I will loose the data? (P.S. please do not refer me to ReadyNAS forums - been there, done that - no help)

I think that the procedure will work as I don't think that the controller stores the hardware data in itself, but rather in the disks.

15 TB disks? Are you from the future? – EEAA Aug 9 '11 at 13:04
1.5 TB (typo edit) – Saariko Aug 9 '11 at 13:15
What's the point of this exercise? – joeqwerty Aug 9 '11 at 13:58
As Chris pointed out: i want to restore to factory default, without loosing my data – Saariko Aug 9 '11 at 14:12
How about you backup your data first? – xeon Aug 9 '11 at 15:35

Looks like you already got your answer. I will agree with the prevailing wisdom here - contact ReadyNAS support. They're likely going to be the only ones that can give you a definitive answer here.

As you can see, ReadyNAS were contacted 12 days ago. No answer yet. I am still waiting. I thought the question is a general one. If I take a set of disks, and replace with a different set, nothing should happen to the data. That's what I am asking. – Saariko Aug 10 '11 at 5:38
@Saariko - there's very little "general" information available about proprietary RAID solutions. My gut feeling is that your data should be there after swapping the disks, but you had better make sure that you have a good backup before doing this. – EEAA Aug 10 '11 at 13:37
