First things first - if you don't have a backup for your data, you should definitely put a backup plan in place.

I tapped the power button, kind of jiggling it (without interrupting the power). The front display flashed on then off, and I jiggled the power button again (without interrupting the power) - the front display came on, and this time looked normal.
Check the preferred shutdown instructions on page 146 here:
Is this what you were seeing?

I tried to access the volumes from my PC but no luck, so I powered the NAS down, this time it being able to do the normal shut down. I powered it back up, and the volumes reappeared and (near as I can tell) all files there.
Hard to say what happened here, or why it recovered after the second boot. There could be some clues in the log zip file, so I suggest downloading that. The info there is hard to interpret, but you could look for errors in system.log, kernel.log, and systemd-journal.log around the time of the slowness.

Prior to a few days ago, access to the NAS via ReadyCloud started having problems.
Hopefully you are aware that ReadyCloud is being discontinued next month.

Last August, the NAS reported that the drive in bay 1 was not mounted, but it was (and no health issues were being reported). I removed and reinstalled the same drive, and it was OK for a while, then the problem returned. I replaced the drive and it mounted and resynced.
While the disk health info the NAS reports can be helpful, it can also be misleading. There are times when a failing disk is reported as healthy. There is a disk test function on the volume setting wheel in the admin web ui - you might want to run that. It will take a while (hours to days, depending on disk size).
