Are you using the latest Folsom version (ie devstack)? Check<BR>your Horizon logs and you'll notice a number of errors when trying to<BR>perform this operation. Perhaps some Horizon folks here have some<BR>knowledge of this, otherwise I can look into it further next week and<BR>file a bug if necessary.<BR><BR>Meanwhile, you can use python-novaclient to perform a 'nova<BR>volume-snapshot-show' which is the information that would be reported<BR>from the Horizon details page you're trying to retrieve.<BR><BR>Thanks,<BR>John<BR><BR>_______________________________________________<BR>Mailing list: <A href="https://launchpad.net/~openstack" rel=nofollow
