On No - "Remove inactive volumes to use the disk. Disk #1,2,3,4,5,6."
First of all the volume became very slow and then went read-only. After a reboot I now get a message "Remove inactive volumes to use the disk. Disk #1,2,3,4,5,6." and the data volume is totally gone!...

If you already made that backup, you can save yourself some time and just delete and re-create the volume or do a factory default and restore your data from backup.
The good news is that MWT has a backup.There were a bunch of ATA errors (both read and write failures), which affected several of the disks. Three of the disks were out-of-sync when the NAS was rebooted, so the array failed to assemble.
No clear cause for the ATA errors at this point. Hopefully not the NAS hardware.

It is unfortunate that you didn't come here before you re-booted. Unless you first made sure your backup was current, that was not the correct action for a read-only volume. The volume goes read-only because it is damaged and any additional writes could further damage it. Rebooting usually results in what you are seeing.
It is almost certain your volume cannot be recovered in a manner that will make it usable, but it may be recoverable enough to make a backup. If you already made that backup, you can save yourself some time and just delete and re-create the volume or do a factory default and restore your data from backup. If you didn't make a backup, then StephenB may be able top help you mount it such that at least most of your data is recoverable once he looks at your logs.
It is unfortunate that Windows has "trained" us to re-boot when something goes wrong. With other OS's, that's often the worst thing you can do.

It must be because of Christmas magic but the array just appeared again from nowhere and is fully working again. I'm capturing the logs in case there's something there to look at but the big question is: Should I reboot?

At some point you'll have to ...
Maybe run some of maintenance functions first. In order I suggest
- disk test
- balance
- scrub
If all three are successful, then reboot.
The disk test and scrub will take a while (12-24 hours),

And definitely back up your data.
