+Quota usage and OpenStack object-store
+======================================
+
+Getting quota information
+-------------------------
+
+The OpenStack dashboard is capable of showing object-store usage, both in terms of
+bytes and number of objects, for each container under the "Project -> Object Store ->
+Containers" tab.
+
+However, to date the dashboard seems to be lacking the integration required to show
+overall usage (namely, the sum over containers) and quota information.
+
+These can be retrieved using the CLI, with the command::
+
+ $ swift stat | grep Bytes:
+
+displaying an output similar to::
+
+ $ swift stat | grep Bytes:
+ Bytes: 410365371827
+ Meta Quota-Bytes: 1000000000000

-S3fs: mount a container as a filesystem
-=================================================
-
-Instead of `Rclone <https://cloud.garr.it/support/kb/openstack/rclone_quick_tutorial/>`_, we can use s3 APIs to connect to object storage and mount containers as filesystems. We may do this by using `s3fs <https://github.com/s3fs-fuse/s3fs-fuse>`_
-
-Install s3fs
-***************
-On Ubuntu machine, you can install the packaged version with the following commands::
-
- $ sudo apt update
- $ sudo apt install s3fs
-
-Check the version::
-
- $ s3fs --version
-
-N.B. These instructions refer to version 1.86 available on Ubuntu 20.04. Different versions may require different configuration.
-
-Uncomment *user_allow_other* option by removing the *#*::
-
- $ nano /etc/fuse.conf
-
-Create application credential
-*****************************
-
-Create and download an `application credential <https://cloud.garr.it/compute/app-credential/>`_ from openstack dashboard as *app-credentials.sh*.
-
-You need to install the Openstack cli as described here in the `cli tutorial <https://cloud.garr.it/compute/install-cli/>`.
-
-Then execute the content of the file::
-
- $ source app-credentials.sh
-
-And create the ec2 credentials::
-
- $ openstack ec2 credentials create -c access -c secret -f value | paste -sd: > ${HOME}/.passwd-s3fs
- $ chmod 600 .passwd-s3fs
-
-Mount a container
-********************
-First, you need to create the container on your openstack project. Then you can mount your container on your local directory.
-Assume that you have a container named *test_container* and a local directory named *test_dir*::
-
- $ s3fs test_container test_dir -o allow_other -o host=https://swift.cloud.garr.it -o use_path_request_style -o umask=000
-
-Now your container has been mounted on *test_dir* directory. You can access it and every change you make inside the directory is istantly made inside the container.
-
-Debug
-*****
-
-If you need to debug, add the following options at the mounting command::
-
- -o dbglevel=info -f -o curldbg
-
-*Note that -f option cause the command to run in foreground, so CTRL+C will kill the command.*
-
-
-Unmount
-*******
-::
-
- $ umount test_dir
