Getting "not enough space on the disk" error when trying to copy files to My Cloud EX2 Ultra (8Tb)

I’ve just bought a My Cloud EX2 Ultra (8Tb) as I had to upgrade from my previous My Cloud due to support for it ending (annoyingly).

I’ve set it to RAID1 mode so I’ve basically got 4Tb of space. I’ve been trying to set files to copy to some shares I created on it (I use GoodSync to copy stuff) and it started fine but after a few hours is now just reporting “Error copying file: There is not enough space on the disk” even though there is still 3.76Tb free (according to the Dashboard). I’ve also tried directly copying files via Windows Explorer and I get exactly the same error - in fact it tells me for example that “9.60Gb is needed to to copy this item” even though there is literally TBs of space available.

This is quite frustrating as I was forced to “upgrade” to this due to support ending for my previous model which worked absolutely fine.
