One of the disk pools on your cluster is nearing, or has reached, maximum capacity.

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

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

Administrator action

To reduce the capacity to below 90% you can:
  • Modify the affected disk pool
  • Remove extraneous data
  • Add capacity to your cluster

If the event persists, gather logs, and then contact EMC Isilon Technical Support for additional troubleshooting. For instructions, see Gathering cluster logs.
