X-RAID2
Hello,
I want to transfer all my data to another kind of NAS, but I also need the drives from which I am transferring data on the new NAS.
Is there a way to gradually, while the transfer progresses, move drives out of the Readynas into the new NAS?
Simply removing a drive breaks the validity of the X-RAID2.
Another way of explaining this would be to be able to slowly empty the Readynas and step by step reconfiguring it as a 5 drives array, then 4 drives array, etc..... without losing data of course.

If you are very skilled with linux, software RAID, and the ext file system then it is possible to move enough data off the NAS to allow the file system and RAID array to be shrunk one disk at a time. But it is risky to do it, and I wouldn't recommend attempting it w/o a backup even if you do have the skills.
Besides being risky, that would be a long process. The array would need to re-sync every time you shrink it.
Since you don't seem to have a backup of your data, you may want to consider keeping the Pro6 as a backup device. In your new NAS, you could then use fewer, larger drives, leaving some slots free for future expansion.
Good.
Can you walk me through it? (in layman's words please. I am a sysadmin on Windows servers)Can't be done in layman's terms. I explain the process here: Reducing-RAID-size-removing-drives-WITHOUT-DATA-LOSS-is-possible
