Help needed - How to restore data from Readynas drive
Looking for the best way to do this transfer. Recently got the RN214 to replace a WD My Book Live 3TB drive.
Started with 4TB drive and backed up a 1 TB, 2tb and 3 tb. I want to repurpose the 2 TB and 3 tb drives (Seagate ironwolf and WD Green drives) and thought it would just automatically do x-raid 5.
Now after reading I would need to start with the 2 TB, add the 3 tb and then the 4tb. Is that correct? What is the easiest way to recover the data from the 4 TB drive and use it as backup?
I have USB enclosures that are working well and used R Linux to recover the data from the 3 tb drive.
Now after reading I would need to start with the 2 TB, add the 3 tb and then the 4tb. Is that correct?
With XRAID that that is correct. If you did that, then you'd end up with a 5 TB volume size (with 1 TB of the 4 TB drive being unused). The general capacity rule for XRAID is "sum the drives and subtract the largest".
NAS-purposed drives (WDC Red, Seagate Ironwolf) are better choices than desktop drives and similar in price.
You have a couple of options here:
Don't use RAID redundancy - switch to flexraid, and then add the repurposed disks as jbod (each disk is it's own volume)
Purchase a new 4 TB drive, so you get RAID-1 on existing 4 TB volume. Then switch to flexraid and create a jbod volume for the ironwolf.
Get two new 4 TB drives, so you get an 8 TB volume, and use the older drives in the USB enclosures to back up the NAS.
Ignore my advice (and Western Digital's) on drive choice, and do a factory reset with all your drives in place.
I'd go with the two new 4 TB drives option + USB backup option myself.

R-Linux doesn't support the BTRFS file system used on the NAS, so you can't use that. You could boot the PC up with a linux Live disk, install mdadm and btrfs, and then mount the drive using the linux shell.
The simpler way is to copy the files from the NAS shares over a wired ethernet network. That can be done with drag-and-drop, though a utility that can verify the copy (teracopy is one) might be a better option.
Note that RAID isn't enough to keep your data safe, so you should have a backup plan for your NAS.
