Comment 3 for bug 1583033

Swift maximum file size is 5GB and if you want to upload bigger files to this storage, it has to be segmented, it's expected behavior according documentation (see http://docs.openstack.org/developer/swift/overview_large_objects.html, "Swift has a limit on the size of a single uploaded object; by default this is 5GB").
So, use swift option -S is decision.

What about "openstack object create" command, in fact I don't know, how it works inside, but if it uses something like swift upload, it could check file size and use segmented upload in case of big files. But I'm not sure, that it's supported feature in openstack cli, no info about large file support in manual to this command. It's question to somebody, more familiar with internal work of openstack cli.
