Parallel Virtual Cluster version 0.9.101

New Feature: Adds VM snapshot sending (vm snapshot send), VM mirroring (vm mirror create), and (offline) mirror promotion (vm mirror promote). Permits transferring VM snapshots to remote clusters, individually or repeatedly, and promoting them to active status, for disaster recovery and migration between clusters.
Breaking Change: Migrates the API daemon into Gunicorn when in production mode. Permits more scalable and performant operation of the API. Requires additional dependency packages on all coordinator nodes (gunicorn, python3-gunicorn, python3-setuptools); upgrade via pvc-ansible is strongly recommended.
Enhancement: Provides whole cluster utilization stats in the cluster status data. Permits better observability into the overall resource utilization of the cluster.
Enhancement: Adds a new storage benchmark format (v2) which includes additional resource utilization statistics. This allows for better evaluation of storage performance impact on the cluster as a whole. The updated format also permits arbitrary benchmark job names for easier parsing and tracking.

  • [API Daemon] Allows scanning of new volumes added manually via other commands
  • [API Daemon/CLI Client] Adds whole cluster utilization statistics to cluster status
  • [API Daemon] Moves production API execution into Gunicorn
  • [API Daemon] Adds a new storage benchmark format (v2) with additional resource tracking
  • [API Daemon] Adds support for named storage benchmark jobs
  • [API Daemon] Fixes a bug in OSD creation which would create split OSDs if --osd-count was set to 1
  • [API Daemon] Adds support for the mirror VM state used by snapshot mirrors
  • [CLI Client] Fixes several output display bugs in various commands and in Worker task outputs
  • [CLI Client] Improves and shrinks the status progress bar output to support longer messages
  • [API Daemon] Adds support for sending snapshots to remote clusters
  • [API Daemon] Adds support for updating and promoting snapshot mirrors to remote clusters
  • [Node Daemon] Improves timeouts during primary/secondary coordinator transitions to avoid deadlocks
  • [Node Daemon] Improves timeouts during keepalive updates to avoid deadlocks
  • [Node Daemon] Refactors fencing thread structure to ensure a single fencing task per cluster and sequential node fences to avoid potential anomalies (e.g. fencing 2 nodes simultaneously)
  • [Node Daemon] Fixes a bug in fencing if VM locks were already freed, leaving VMs in an invalid state
  • [Node Daemon] Increases the wait time during system startup to ensure Zookeeper has more time to synchronize
