What is Virtual SAN Cluster Rebalancing

When any capacity device in your cluster reaches 80 percent utilization, Virtual SAN automatically rebalances the cluster, until the utilization of all capacity devices is below the threshold.

balance

Cluster rebalancing evenly distributes resources across the cluster to maintain consistent performance and availability.

Other operations can initiate cluster rebalancing:

  • If Virtual SAN detects hardware failures on the cluster

  • If Virtual SAN hosts are placed in maintenance mode with the Full data migration option

  • If Virtual SAN hosts are placed in maintenance mode with Ensure accessibility when objects assigned FTT=0 reside on the host.

To provide enough space for maintenance and reprotection,

Manual Rebalance of vSAN Cluster

You can manually rebalance through the cluster health check, or by using RVC commands.

manual rebalance

If the Virtual SAN disk balance health check fails, you can initiate a manual rebalance in the vSphere Web Client. Under Cluster health, access the Virtual SAN Disk Balance health check, and click the Rebalance Disks button.

Use the following RVC commands to manually rebalance the cluster:

  • vsan.check_limits. Verifies whether any capacity device in the Virtual SAN cluster is approaching the 80 percent threshold limit.

  • vsan.proactive_rebalance [opts]<Path to ClusterComputeResource> –start. Manually starts the rebalance operation. When you run the command, Virtual SAN scans

Automatic Rebalance of vSAN Cluster

Virtual SAN automatically rebalances the Virtual SAN cluster when a capacity device reaches 80 percent utilization. Rebalancing also occurs when you place a Virtual SAN host in maintenance mode.Its By Default.

autorebalance

Run the following RVC commands to monitor the rebalance operation in the cluster:

  • vsan.check_limits. Verifies whether the disk space utilization is balanced in the cluster.

  • vsan.whatif_host_failures. Analyzes the current capacity utilization per host, interprets whether a single host failure can force the cluster to run out of space for reprotection, and analyzes how a host failure might impact cluster capacity, cache reservation, and cluster components.
