ReadyNAS 312 factory reset itself; have I just lost all my data?
I have a ReadyNAS 312 with two 2T drives in it. It has been working flawlessly for years, but one of the drives died. I replaced it with a brand new 2T drive, and the machine factory reset itself! ...
Just to close the loop on this one: the NAS was in Safe Mode because the one good disk was not seated properly. Once that was fixed, and a new second drive was installed, the NAS rebooted with all of the original settings and sync'd itself over the next 9 hours or so. Everything is working great now, although I will have to format the USB drive from the CLI (if possible).
Here are two takeaways:
1) I think the OS should inform the user in the UI when the NAS is booted in Safe Mode. Some banner or some such indicating the status would have saved a bunch of time and anguish. :)
2) It would be great if the USB drive as either unformatted, or formatted with an unrecognized file system would show up in the UI and allow us to format it there.
Other than that, it's very comforting to know that the NAS did it's job well and this great community helped keep the freak out to a minimum :)

We did manage to put the USB drive on a Mac and format it as ExFAT using Disk Utility.
ExFAT isn't supported by the NAS. You can use ntfs, ext4, or btrfs. (Fat32 would also work, but is a bad choice because of the file size limit).
You should be able to format the USB drive in any linux PC. You'd partition the disk with parted (if needed). I suggest using the existing partition that was created on the Mac.
You'd then create the file system using mkfs.ext4 or mkfs.ntfs. Either way the disk shouldn't be mounted. And of course you do need to be very careful to format (or partition) the correct drive.

I did a `mount` command from the ssh login and I don't see the drive anywhere in /dev.
Do you mean that you ran mount with no arguments (or perhaps mount -l )?
As I said before ExFAT isn't supported. So it's not surprising that you didn't see it mounted. It should still have a device path (/dev/sdX )
You should be able to distinguish the usb drive from the rest (and find its device path) with ls -al /dev/disk/by-id
And from there you should be able to create the file system (using the existing partition you created on the Mac).
