ReadyNAS 516 Best Practice
Two questions: First, I'm about to replace a disk (smaller disk with a bigger one). Is it best to shut down the box (to take out a 4TB drive and replace it with an 8TB) or can you simply do a hot sw...

Hmm. I shut down the NAS and replaced the bad 4TB drive with the one I had taken out. On reboot it tells me that there is no volume. The four good drives are now colored red with the replaced 4TB drive in black.
Did I lose the entire volume?

Not a good idea (and not what I suggested).

Hopefully not. You could still potentially try what I suggested - putting the 4 TB drive you removed back in it's original slot. That is, put everything back the way it was before you hot-swapped in the 8 TB drive.
But If you do try that now, use the boot menu to boot up the volume read-only.

I might have misunderstood you. But I have a message that says "Remove inactive volumes to use the disk. #2, #3, #4, #6."
Why are those disks inactive?

Where do I find the boot menu?

The system can't figure out how to assemble your data volume. I think it's starting with the disk you just re-added, and can't connect it with any of the others.
I suspect that will likely happen again (even if you put the disks back in there original positions). But I think it's still worth a try. Mounting read-only should prevent the system from doing more damage (writing to those the disks) if I am wrong.
