Hi, I am seeing unwanted errors/warnings displayed when I am using glance cache management and executing glance-cache-prefetcher command. Here I have only local disk (file) as my datastore, but it gives me warnings about setting other backends and errors about sheepdog setups. The command eventually work though, I just don't want unwanted errors and warnings when I have configured everything right.

My setup is in Icehouse in Ubuntu 14.04. When I configured it in Havana no error/warnings appeared.

Can anyone advise me what I can do to make these messages disappear?

sudo glance-cache-prefetcher
