Weekly news #353

Weekly status for the week of 1st July to 7th July.

Introduction

In the past week, LXD received several bug fixes as well as support for accessing Dell PowerFlex storage over SDC.

Dell PowerFlex storage - SDC operation mode

Dell PowerFlex is a software-defined storage solution. LXD offered access to the PowerFlex storage clusters using NVMe/TCP, but now it also supports access over Dell’s Storage Data Client (SDC).

To enforce the SDC mode, set the powerflex.mode option to sdc. If the mode is not set, LXD will first try to use nvme mode and then fall back to the sdc mode.

Note that when using the SDC, LXD requires it to already be connected to the Dell Metadata Manager (MDM), as LXD does not set up the SDC.

Bugfixes

  • Fixed the issue where instances backed by a degraded ZFS pool would not start. Previously, LXD considered a degraded ZFS pool as non-functional. However, a degraded ZFS pool means that one or more replicas are offline, but enough replicas remain available for ZFS to function normally.

  • Fixed an issue where lxc would panic when adding a remote server with an empty address. The remote address is now properly validated and lxc will error out with an intuitive error message.

  • Fixed an issue where instances would not be started (restored to a running state) after a LXD restart. If an earlier shutdown timed out, the instance could result in a stopped state while the cleanup of host devices was still ongoing. This caused issues with state reporting when the cleanup finished.
