Easily upload files or directories to ceph.com for analysis by Ceph
developers.

Each invocation uploads files or directories to a separate directory
with a unique tag.  That tag can be passed to a developer or
referenced in a bug report (http://tracker.ceph.com/).  Once the
upload completes, the directory is marked non-readable and
non-writeable to prevent access or modification by other users.

WARNING:
  Basic measures are taken to make posted data be visible only to
  developers with access to ceph.com infrastructure. However, users
  should think twice and/or take appropriate precautions before
  posting potentially sensitive data (for example, logs or data
  directories that contain Ceph secrets).

Options:
  -d|--description <desc>    Description for this post
