Hi stackers,

I have the same problem than Brian.
I use the last milestone proposed.

I create a volume and a snapshot from this volume.
And if I try to create a new volume from the created snapshot, I cannot list volume anymore:

I check my disk and I've enough space to create the new volume. I check the database (nova.volume) and I saw a new empty entry (lot of null values).
I made this test through the Nova APIs but I get the same result with Horizon.
