0.9.102

Parallel Virtual Cluster version 0.9.102

• [CLI Client] Fixes several bugs around local connection handling and connection listings

0.9.101

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

0.9.100

Parallel Virtual Cluster version 0.9.100

• [API Daemon] Improves the handling of "detect:" disk strings on newer systems by leveraging the "nvme" command
• [Client CLI] Update help text about "detect:" disk strings
• [Meta] Updates deprecation warnings and updates builder to only add this version for Debian 12 (Bookworm)

0.9.99

Parallel Virtual Cluster version 0.9.99

Deprecation Warning (Project): Version 0.9.99 is the last version of PVC that will support Debian 10 and Debian 11. All future versions of PVC will require Debian 12 as the base OS. Leverage the distribution upgrade oneshot playbooks in "pvc-ansible" to upgrade systems to continue receiving new versions of PVC.
Deprecation Warning: pvc vm backup commands are now deprecated and will be removed in a future version. Use pvc vm snapshot commands instead.
Breaking Change: The on-disk format of VM snapshot exports differs from backup exports, and the PVC autobackup system now leverages these. It is recommended to start fresh with a new tree of backups for pvc autobackup for maximum compatibility.
Breaking Change: VM autobackups now run in pvcworkerd instead of the CLI client directly, allowing them to be triggerd from any node (or externally). It is important to apply the timer unit changes from the pvc-ansible role after upgrading to 0.9.99 to avoid duplicate runs.
Usage Note: VM snapshots are displayed in the pvc vm list and pvc vm info outputs, not in a unique "list" endpoint.

• [API Daemon] Adds a proper error when an invalid provisioner profile is specified
• [Node Daemon] Sorts Ceph pools properly in node keepalive to avoid incorrect ordering
