openATTIC 2.0.15 beta has been released

Did you notice the long list of changelog entries for version 2.0.15? The openATTIC team worked hard to include several new features and also fixed some important bugs.

This release includes a number of Ceph-related improvements, but also several other noticeable changes.

One big Ceph highlight is likely the handling of erasure code profiles in openATTIC. Different erasure code profiles can now be selected when creating an erasure-coded Ceph pool. The creation and removal of EC profiles is supported as well.

In a Ceph pool's detail view in the web UI, we've now added performance data graphs, to visualize the data collected by the Nagios backend for each pool.

Nagios monitoring for Ceph also evolved and now contains a new plugin to collect the performance data of RADOS block devices (RBDs). The data can already be queried via the REST API, visualizing it on the Web UI will be added next.

On the "traditional" storage management side, it's now possible to create a new initiator host during the creation of an iSCSI or Fibre Channel target via the block storage wizard. This makes this workflow more straight-forward, as one does not have to remember to create a host first before creating a new share.

We also fixed a small "gotcha": now, it's no longer possible to accidentally lock yourself out of the UI by removing your own privileges.

Due to increasing demand, we added preliminary support for Ubuntu Linux 16.04 LTS (aka "Xenial Xerus") and with it support for Django 1.8 as well as Django REST framework 3. This support will be further refined and improved in upcoming releases. We look forward to hearing about your experiences with installing openATTIC on Ubuntu 16.04 - let us know how it went!

On the backend side, the logging mechanism of the Django backend and the error responses generated by the REST API were also revised. In case of an error, you will receive a more precise status code and an error message, if possible. The reasons for internal server errors are written into the log file /var/log/openattic/openattic.log now. Also, many backend modules were refactored to adhere to the PEP8 coding style proposed by the Python project.

To download and install openATTIC, please follow the installation instructions in the documentation.

Please note that 2.0.15 is still a beta version. As usual, handle with care and make sure to create backups of your data!
