Introduction

The LXD team is very excited to announce the release of LXD 4.17!

This release comes with a couple of major features, our reworked disaster recovery mechanism and the ability to perform cluster member evacuations. On top of that, lxc info got a bit of a rework, and there were a number of other smaller improvements around events and the resources API.

LXD 4.17 is the first release coming with major features that went through our new specification process. The relevant specifications are linked below and the entire list of specifications can be found here: Specifications - Linux Containers Forum

Enjoy!

New features and highlights

lxd import replaced by new lxd recover

For a long time, LXD’s disaster recovery story was based on our lxd import command. This would go look for a specified instance at the expected path on the filesystem, read the backup.yaml file that’s part of instance storage and based on that information would recreate the instance’s database entry.

While this definitely worked and was successfully used by quite a few people who for one reason or another lost their LXD database, it was limited to instances only and was requiring quite a bit of manual intervention to get the instance filesystem in place so it could be read and imported by LXD.

This has now all been replaced by a new lxd recover command. This is an interactive command somewhat similar to lxd init. It allows importing both instances and custom storage volumes and supports both pre-existing storage pools and missing storage pools.

The lxd recover experience starts with a summary of the existing storage pools, then any missing storage pool can be added. This is then followed by a scan of all storage pools for missing instances or custom storage volumes. As part of the scan, any missing dependencies (profiles, projects, networks, …) are also reported. Once the user has had a chance to add any of those missing dependencies, they can proceed with the import.

Cluster member evacuation

Production cluster members all require maintenance at one time or another.
Whether it’s for routine system updates or for hardware maintenance, there are times where the administrator will need all instances on the system to be stopped or moved away.

That’s what the new cluster evacuation API and CLI makes very easy to do.
The administrator can now just run lxc cluster evacuate lxd01 and all instances on lxd01 will either be migrated to another cluster member or will be stopped.

The default behavior is to attempt a migration so long as the instance isn’t using local resources that makes it impossible to migrate. If an instance can’t be migrated, then it will instead be stopped. This behavior can be controlled through the cluster.evacuate configuration option.

Once the system is fully back online, running lxc cluster restore lxd01 will move back any instance that was moved away and then bring all instances back up.

Reworked lxc info output

The output of lxc info has been reworked quite a bit. The most visible change is likely going to be the tables to show the list of snapshots and backups.
On top of that, the network information and statistics have been cleaned up and expanded and it’s now using IEC units for memory and disk information.

The result looks something like this:

Requestor address in lifecycle event

In addition to the protocol and username which was already recorded as part of lifecycle events, the requestor’s IP address is also now recorded.

location: abydos
metadata:
  action: instance-restarted
  requestor:
    address: '[2602:fc62:b:1000:ea29:c5e9:8544:e32d]:36276'
    protocol: candid
    username: stgraber@stgraber.net
  source: /1.0/instances/nsd01?project=core
timestamp: "2021-08-06T04:53:17.571633526Z"
type: lifecycle

USB GPU support in the resources API

The LXD resources API (lxc info --resources) will now properly report USB GPUs like those based on DisplayLink chips.

gpu:
  cards:
  - driver: evdi
    driver_version: 5.11.0-7620-generic
    drm:
      id: 0
      card_name: card0
      card_device: "226:0"
      control_name: controlD64
      control_device: "226:0"
    numa_node: 0
    usb_address: "2:6"

Monitoring of all projects in lxc monitor

A new --all-projects option was added to lxc monitor which as the name implies will allow watching events for all projects rather than just the current one.

Alternative format options in lxc monitor

Again in lxc monitor, a --format option was added which allows for three different kind of output:

  • pretty (same as with --pretty)
  • yaml (same as default behavior)
  • json
