Weekly status for the week of the 22nd August to the 28th August.

Introduction

The past week saw continued progress on the new object storage buckets feature as we work towards adding local storage pool support. In addition there were a few bug fixes and improvements across most of our projects.

LXD

Improvements:

  • Added new lxd_cpu_effective_total metric to metrics exporter. Which reports the total number of effective CPUs.
  • Added storage-pool name to the instance-created lifecycle event.
  • Added automatic admin credential generation when creating an object storage bucket using lxc storage bucket create. The generated credentials will be displayed at the end of the command and can also be managed using the lxc storage bucket key commands.
  • ZFS storage pool top-level datasets are now initialized at storage pool mount time. This means any missing datasets are created as needed and LXD specified properties are applied to both new and existing datasets.

Bug fixes:

  • Fixed a typo in the cephobject.radosgw.endpoint* setting names, and added a patch to automatically convert any existing usage of the old settings with the new correct ones.
  • The data type used for lxd_cpu_seconds_total metrics field in the metrics exporter has been changed from int to float.

LXCFS

Improvements:

  • Set oom_score_adj of lxcfs process to -1000 in the LXCFS init scripts to avoid the process being killed in an out of memory situation, as if the LXCFS process is killed it will require all containers to be restarted.

Distrobuilder

Improvements:

  • Added support for using templates in actions.
  • Improvements to logging output.
  • Improvements to Alpine image building to always download from latest point release and handle edge release.
  • Improvements to Oracle image building to aid finding the latest release version.

Dqlite (RAFT library)

Bug fixes:

  • Fixed memory leak in uvLoadClosedSegment caused when one killed node rejoins the cluster.

Dqlite (database)

Bug fixes:

  • Fixed non-dqlite return codes that were returned from some functions in the public API in certain circumstances.
  • Unify address parsing and fix IPv6 support.

Dqlite (Go bindings)

Bug fixes:

  • If dqlite_node_create fails, don’t try and de-reference NULL struct dqlite_node argument.
  • Normalize error string capitalization.

YouTube videos

The LXD team is running a YouTube channel with live streams covering LXD releases and weekly videos on different aspects of LXD. You may want to give it a watch and/or subscribe for more content in the coming weeks.
