Holding the power button down for 5 seconds or so should also forcibly shut it down, so try that first.
If the unit is locked up (as it sounds like it is), you really have no choice but to do this. If it was just resyncing the disk (which could have failed while that was being done), then there shouldn't be any data loss. You can just remove that disk, and power up again.
Note that if another disk had a read error during the resync, then the resync would also fail. So once you've checked that the data is ok, then you should probably run a disk test from the volume settings menu. Then download the log zip file after that completes. Examine the SMART stats in disk_info.log, and look in system.log and kernel.log for disk and btrfs errors. If everything looks healthy, then you can hot-insert a replacement disk.
RAIDar doesnt find any storage on my network.
I do have a backup. So i am not worried about data loss. Other than the hassle of pulling it all together again.
The blinking disk LED does mean the disk either has failed or is being resynced to the array. The panel message suggests a resync - though normally I'd expect the NAS to be accessible during a resync (and that RAIDar would also find it).
You could of course wait longer and see what happens.
Another option is to power down the NAS, remove the disk that is blinking, and then try to boot without it. If that fails, it's probably most direct to do a factory default and restore the data from your backup. Either way, I'd test the disk in a PC with vendor tools before adding it back (Lifeguard for WD disks, Seatools for Seagate).
I dont think anything is happening. its been stuck on that percentage for 24hrs at least.
The power button isnt doing anything. I was worried that a hard reset might break something.

Thanks for your help. I did a hard reset and it all turned back on no problems. I was scared this would ruin everything, but it didnt!
I didnt really know what i was looking for in the logs but this drive has apparently been having issues for a month or so and i didnt realise. It looks like one of my others might be on the way out as well.
(these were both pretty old drives and of the green variety)
I am just putting my shiny new replacement in now.
