Good day, I have a messy issue with a lot of uncertainty and forgotten facts because this happened over a year ago and I'm now trying to recover my data. I have a ReadyNAS, RNDU4000. Firmware 6.10.5 hotfix 1. Three disks installed 1, 2 & 4.
About a year ago I noticed that I could not access my NAS and it had an error message in the display, that I don't remember at the moment. I did a reboot and could access the NAS interface again, but no files. I then saw several of warnings and error messages, indicating that Disk 2 was going bad. "Detected increasning ATA error count: [24880] on disk 2".
I also got messages about disks 1,2,4 being inactive (I don't have a disk 3)
From here I have done a lot of things I have read about that you shouldn't do and I don't remember in what order 🙂 I'm pretty sure I have gotten the RAID off sync and I doubt it will work if i change disk 2. (I have exported a log, so I guess the facts can be found there.)
My question is - What is the best way to restore the data? I don't need to get the system running again. Just want a backup of all files I had. I think the disks were setup as RAID 5.

Or is it a lost battle?
I think the best path is data recovery.
If you want to try that on your own, you'd need a way to connect the disks to a Windows PC and try ReclaiMe software
There are other folks who offer this (some might be local to you). Best to check whether they have experience with mdadm raid + btrfs before you contract with them - many folks are more experienced with PC/Mac data recovery.
After you get the data back (being positive!) - you should put a backup plan in place. Devices can fail, and RAID isn't enough to keep your data safe.
Are there any tool that can recover directly from the NAS thought the network, so I don't have to connect the disks individually to my computer. I only have one SATA/USB connector available at the moment and I guess would be good to let the recovery program have access to all 3 drives when it's doing its magic.... just guessing though.

You'd need to get suitable adapter/docks, so you can connect all three drives. There are some that handle multiple drives. Prices vary, but you can find 4 bay enclosures for about $125 USD.
