Problems with S3 Object Storage Clients

Some problems were encountered on Brno site while using S3 command-line clients to manage data on Swift Object Storage. Due to misconfiguration, commonly used data operations didn't work (e.g., it wasn't possible to save new data to Swift).

Swift works best with clients propagated by OpenStack, the best one being python-swiftclient.

If You encounter problems, try the following:

  • Enforce https instead of http (worked for davix).
  • Check default values (s3cmd requires overwriting parameter --host-bucket=object-store.cloud.muni.cz).
  • Look into the logs (many tools come with a --debug option).
