About two Years ago, the LINSTOR driver for CloudStack was merged into the CloudStack code base, and it has received updates since then. Rene gives a quick overview of LINSTOR/DRBD and the driver, followed by more details on recently added features. One is the ability to optionally store data snapshots on secondary storage, about making deep copies of templates vs using snapshots, about using LINSTOR/DRBD on XCP-ng hypervisors under Apache CloudStack, and (if finished by November) about VM-snapshots on LINSTOR/DRBD. ----------------------------------------- The CloudStack Collaboration Conference 2023 took place on 23-24th November. The conference, arranged by a group of volunteers from the Apache CloudStack Community, took place in the voco hotel, in Porte de Clichy, Paris. It hosted over 350 attendees, with 47 speakers holding technical talks, user stories, new features and integrations presentations and more.
