Nutanix NCP-DS Question Answer

An administrator of an existing Nutanix cluster running Kubernetes with multiple PODs notices

that NCC checks report that some volume groups experience the following error:

Node x.x.x.x:

FAIL: Volume Group pvc-XXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX space

usage (90%)

The administrator checks the volume group usage from the Kubernetes pod and get different

usage results. The current stats are 55% used space.

The results of the NCC check do not match what manually-executed checks report.

What is the cause of this behavior ?

The garbage collection process has yet to run.

The NCC checks need to be updated to the latest version.

Volumes has not received the needed UNMAP commands.

Kubernetes is not correctly reporting its storage usage.
