PowerScale: Cluster is Running Low on Free Space

Event message: 

400100007 SW_JOBENG_CLUSTER_FULL 400000000 Low free space 

Clustername-1 - Cluster is running low on free space: free space (1.99xxx%) < job-config core.free_blocks_pct_threshold_lo (2%)

If the cluster is too close to maximum capacity, there might be insufficient space to restripe data if there is a hardware failure. This could put your data at risk.

In addition, should the cluster be allowed to approach 100% used capacity, important system processes may cease to function properly until disk usage is reduced.

Full cluster due to capacity management.

To ensure that your cluster always has enough free space available, follow OneFS best practices for capacity management: Cluster capacity management | Dell PowerScale OneFS: Best Practices | Dell Technologies Info Hub 

A few items to help relief capacity:

• Modify the affected disk pool
• Remove extraneous data 
• Remove old or unneeded snapshots
• Add new nodes to existing clusters or pools
• Replace smaller-capacity nodes with larger-capacity nodes
• Create more clusters.
