### Human: Can you tell about NCC Health Check: ec_enablement_check. ### Assistant: The NCC health check ec_enablement_check checks if erasure coding should be enabled or disabled on a storage container.. The NCC health check plugin ec_enablement_check reports whether Erasure Coding data savings technique would be efficient for each of the storage containers in a cluster.This check recommends enabling erasure coding in cases where estimated EC savings are significant.

Running the NCC Check

It can be run as part of the complete NCC check by running

ncc health_checks run_all

Or individually as:

ncc health_checks run_all

You can also run the checks from the Prism web console Health page: select Actions > Run Checks. Select All checks and click Run.

This check is scheduled to run every 1 day, by default.This check will generate a severity INFO alert A101082 after 1 failure.

Sample output

For status: PASS

ncc health_checks run_all

Troubleshooting

The NCC ec_enablement_check uses the 18% estimated savings threshold for recommendation to enable EC on specific storage containers in a Nutanix cluster.Not every workload is suitable for erasure coding, as detailed in the Prism Web Console guide.

Note: In NCC version 4.6.5, this check might recommend enabling EC on the NutanixManagementShare, which is a storage container for Nutanix-only features and cannot be updated or deleted in Prism UI.

Nutanix Engineering is aware of the issue and is working on a solution.

Resolving the issue

Enable erasure coding only on the storage containers identified by this NCC check.

Realizing the EC space savings will take at least two Curator full scans to do the encoding and remove the excessive replicas. Curator full scans are scheduled to run every 6 hours by default. For more information on Curator scan types and schedules, see KB 2101.

Collecting additional information

Before collecting additional information, upgrade NCC. For information on upgrading NCC, see KB 2871.Collect the NCC output file ncc-output-latest.log. For information on collecting the output file, see KB 2871.Collect Logbay bundle using the following command. For more information on Logbay, see KB 6691. 
	nutanix@cvm$ logbay collect --aggregate=true
	

Attaching files to the case

Attach the files at the bottom of the support case on the support portal. If the size of the NCC log bundle being uploaded exceeds 5 GB, Nutanix recommends using the Nutanix FTP server due to supported size limitations. See KB 1294.. ### Human: Now explain this as a Nutanix support agent summarizing the answer step by step. In case, you don't know the answer say - I don't know.
