Hung NCC check?

I think I have a hung NCC check somewhere in my v4.7.3 cluster. When I try and run it myself I get the following message: "RPC failed with error: NCC is already running."

 

Is there any way to track this down and terminate it? I've been attempting this with that same error message for over an hour now.

 

Thanks!

Re: Hung NCC check?

Howdy, I've moved your post from the Community Edition forum to here.

 

Could you send in a support ticket real quick, and support can pop on a web conference with you and clear this up?

Re: Hung NCC check?

You can use the 'ps -ef' command to find the node where ncc is running.

You can kill ncc with the 'kill -9 [PID]' command, but this is not a good idea.

If you can open a support ticket, you should get support~^^

Re: Hung NCC check?

Thanks - I ended up calling support and we used the following command to resolve;

 

sudo python ncc/bin/health_client.py --cancel_master_task=True

 

I agree this was likely more graceful than doing a kill [PID] on the CVM - ncc is happy and healthy again! Thanks again for the guidance.

Good to know that support was able to fix it very quickly.

Also to note, ^^ The above mentioned command can be destructive and should never be run without the supervision of Nutanix Support Engineer. Failure to do so may cause irreversible damage/downtime to the Nutanix cluster
