NCC Checks - Volume Groups | Nutanix Community
Skip to main content
Hi all



When doing NCC checks, I get a report(example1) that some volume groups usage is high (95%).



example1:

Detailed information for vg_space_usage_check:

Node 10.x.x.x:

FAIL: Volume Group pvc-xxxxxx-9xxx-11x9-bf59-xxxxx8d87c391 space usage (95 😵 above 90 %

_

The volume group is mounted to Kubernetes pod running in a Karbon cluster.

My issue is that, when checking usage of the volume group from within the kubernetes pod, I get different usage results, current stats are 24% used, 76% free.



The NCC check and the manual check results don't match.



NOTE: There is a clean-up mechanism, so disk usage does go up and down.



I have re-ran the ncc checks several times, they yield the same stats (95% usage), thou the usage from the pod is 24%(currently).



Can you please elaborate on how the NCC vg_space_usage_check work?

And what else to look at to further investigate the mismatch of stats.

Hi KeoNanne



I am pretty sure we aren't able to tell that your reclaiming space but give me some time to verify.
looks like we don't have trim on for the karbon vms. I will file a ticket.
Thanks dlink7

How would I follow the progression of the ticket?
It's a internal engineering ticket so you won't be able to. I would follow up with your account team. You could open a support ticket I guess.
