[mheon]

We initialized the map to show them, but didn't actually copy them in, so they weren't being displayed.

Well that doesn't look right. I think volume inspect is rather broken for remote.

Code LGTM but the remote tests aren't happy

[mheon]

I have rewritten the remote endpoint for volume inspect in a way that will hopefully resolve this

[mheon]

Tests passing now
