Disaster on a readynas 314 - need advice please
Going to simplify this - essentially this is all because of the 6.9.2 update causing NAS to not boot up after update. Not happy. I had 2 x 3TB drives as RAID1 in a 4 bay NAS. I installed a new 3TB...
Also forgot to mention if I have just the 2x3TB disks, or 3x3TB disk in, it hangs on WELCOME NETGEAR STORAGE......... for ever.
The sequence of events is a bit complicated, but if I am reading this correctly, you now have a degraded RAID-5 array on the 3x3TB disks. That is assuming that the 4 TB drive was also synced to the volume, but then reformatted using the factory reset. If that's the case, you'll need all three disks to recover the data.
What you should have done is put a backup plan in place before you started (or at least after the first mistake). RAID isn't enough to keep your data safe. Equipment fails, people make mistakes, and there are also the risks of theft, power surges from nearby lightning, fire, etc.
That said, the question now is what to do to get your data back. Your best options are to use paid Netgear support (data recovery might be needed) or possibly try connecting the three drives to a Windows PC and use ReclaiMe. Netgear's data recovery service is outlined here: https://kb.netgear.com/69/ReadyNAS-Data-Recovery-Diagnostics-Scope-of-Service
6.9.3 (beta) has a new "safe" mode that might help here though - so you could try installing that, and then power down, insert the old array, and then power up again. Perhaps wait for mdgm-ntgr to chime in, he can give you more information on whether that safe mode would help in your situation. Installing beta firmware might have issues if you then move to paid support.
Do you have experience with linux shell commands?
Thanks Stephen, definetely complicated. After this experience I will have a failsafe backup plan in place. As I said this data is my life and memories and are worth my world.
That being said I'll need to get pricing on paid support but would be happy to go down this path.
Unfortunately I only have a notebook and so ReclaiMe might be a bit tricky, but I guess I could buy a computer for this purpose.
Would love to hear about 6.9.3 mdgm response and see whether that might work.
What is the go if I install all three disks and then boot menu (if it works) and reinstall OS, is that a good idea to get it started again?
Can I also ask on a RAID5 where is the OS installed? (I dont understand why it doesnt boot atm).
Also is the NAS reading anything off itself when it is booting, i.e. are all the config files, and setup (like the PWs, etc) stored on the drive or the 31400? I.e If I installed a fresh 4TB and called the volume XXX, with the password to readynas as X1X1X1, and then I removed that only drive, and replaced it with a brand new drive and called it YYY, with password Y1Y1Y1, and then removed that drive and put XXX back it, would everything from XXX come back? Or would it be a red volume shown in volume?
P.S. what hours are paid support?
I don't work for Netgear, and I think some of your questions are best answered by them.

The operating system is stored in a small partition on the drives (4 GB). That uses RAID-1 mirroring (that is, if you have 4 drives, it is mirrored on all of them). That allows the system to boot from any drive.
Settings are also stored on the drive.
There is a firmware install also saved in the RN314 flash. That is updated whenever you do a firmware update. If you migrate disks to the RN314, the system looks at the OS partition during the boot. If the OS is newer than the flash, then the boot process updates the flash to the newer version. Similarly, if the OS is older than the flash, the boot process updates the OS.
At least part of the new safe mode feature needs to be in the boot loader, since it is supposed to boot up even if the OS partition is corrupted. But I don't much information on that.

My main concern is the risk of doing more damage by experimenting. You can mitigate this by cloning your three disks (though of course that requires you to purchase more drives).

USB docks will work, though you might also need a USB hub.
