The MultiScan job, which combines the functionality of AutoBalance and Collect, automatically runs after a group change that adds a device to the cluster. AutoBalance(Lin) and/or Collect only run manually if MultiScan has been disabled.
Note: Scalability enhancements in OneFS 8.2 and later mean that fewer group change notifications are received. This results in MultiScan being triggered less frequently. To compensate for this, MultiScan is now started when:
• Drives have been unavailable for long enough to warrant a Collect job, which triggers MultiScan to start both its AutoBalance and Collect phases.
