Hi Dongcan

It looks like you may have multiple glance-api services configured with
different
glance_store backends i.e one with filesystem and the other with vsphere.

Or it could be that you changed the glance_store backend configuration
between the two snapshot operations. Can you check again ?

If you try to upload a new image it should be using the vsphere backend
according to your configuration. Please ping me on IRC (sabari) on
#openstack-glance,
I can help you more quickly.

Thanks
Sabari
