Can't update data instance /info

[stuarteberg]

I have a grayscale dataset in a gbucket that I uploaded with incorrect /info. Specifically the resolution isn't [8,8,8], it's supposed to be [12,12,12].

According to /api/help/uint8blk, the /info endpoint allows POST, but when I tried to update that field, it seems not to make a difference. Here's a log of my attempt. It makes no difference if I restart the server.

In [38]: r = requests.get('http://emdata3:8800/api/node/d33093f0ea3240c5ae725b4655ec2ff6/grayscale/info')

In [39]: info = r.json()

In [40]: info['Extended']['VoxelSize'] = [12,12,12]

In [41]: r = requests.post('http://emdata3:8800/api/node/d33093f0ea3240c5ae725b4655ec2ff6/grayscale/info', json=info)

In [42]: r.status_code
Out[42]: 200

In [43]: r = requests.get('http://emdata3:8800/api/node/d33093f0ea3240c5ae725b4655ec2ff6/grayscale/info')

In [44]: r.json()['Extended']['VoxelSize']
Out[44]: [8, 8, 8]

This seems to be an issue with labelmap instances, too. For instance, I can't edit the MaxDownresLevel after the instance has been created.
