Issue

Error message in NetApp SolidFire Active IQ: 

• blockClusterFull
• Add additional capacity or free up capacity as soon as possible
• 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.
• There is not enough free block storage space to support a single node loss. To resolve this fault, add another storage to the storage cluster.
