Applies to

  • HCI or AFA clusters running Element Software and configured to report to ActiveIQ
  • Element management node (mNode) version 11.3 or above running management services 2.15.28
  • Hybrid Cloud Control (HCC) version 2.15

Issue

Symptoms can vary across the storage cluster (AFA or HCI storage nodes running Element Software) and HCI compute nodes.

For Storage Clusters:

  • the storage cluster is no longer reporting to ActiveIQ

For Compute nodes:

  • the compute nodes are no longer reporting to ActiveIQ
  • the compute nodes may not show in Hybrid Cloud Control (HCC) on the mNode

The common denominator for both environments is an out of memory error in the container logs for the mnode-svc-aiq-collector service on the mNode.

In /var/log/syslog:

Memory cgroup out of memory
