Description

  • Linux clients are typically not set up to run TRIM automatically to reclaim block space, it causes inaccurate capacity reporting and triggers alerts such as:
    • "blockClusterFull - Due to high capacity consumption Helix data protection will not recover if a node fails. Creating new Volumes or Snapshots is not permitted until additional capacity is available. Add additional capacity or free up capacity immediately.". 
  • In this scenario, TRIM must be manually set to reclaim the space and clear the alert.
