btrfs check gave me a possible hint:

   Checking filesystem on /dev/mapper/xmnt-cold15
   UUID: 6e035cfe-5b47-406a-998f-b8ee6567abbc
   [1/7] checking root items
   [2/7] checking extents
   [3/7] checking free space tree
   cache and super generation don't match, space cache will be invalidated
   [4/7] checking fs roots
   [no other errors]

But mounting with clear_cache,space_cache=v2 didn't help, df still shows 0
bytes free, "btrfs f us" still shows 3tb unallocated. I'll play around with
it more...
