Hardlinks not being written in new versioned layout

[andrewjbtw]

The new versioned layout for shelving was deployed this morning. Files are supposed to be written to both the old layout (the Stacks approach up until now) and the new layout, with hardlinks between the content files in both layouts.

It looks like files are only being written to the new layout, with no hardlinks to the content files in order to main compatibility with the earlier Stacks layout. The result is that items in the new layout cannot be viewed.

Example: https://argo.stanford.edu/view/druid:tz668mh0034

On Stacks:

The count of links using ls indicate there are no hardlinks from the content files:

Looks like some items are being written as expected:
