ndctl

Utility for managing Non-Volatile DIMMs. More information: https://manned.org/ndctl.

• Create an ‘fsdax’ mode namespace:

ndctl create-namespace --mode=fsdax

• Change the mode of a namespace to ‘raw’:

ndctl create-namespace --reconfigure=namespaceX.Y --mode=raw

• Check a sector mode namespace for consistency, and repair if needed:

ndctl check-namespace --repair namespaceX.Y

• List all namespaces, regions, and buses (including disabled ones):

ndctl list --namespaces --regions --buses --idle

• List a specific namespace and include lots of additional information:

ndctl list -vvv --namespace=namespaceX.Y

• Run a monitor to watch for SMART health events for NVDIMMs on the ‘ACPI.NFIT’ bus:

ndctl monitor --bus=ACPI.NFIT

• Remove a namespace (when applicable) or reset it to an initial state:

ndctl destroy-namespace --force namespaceX.Y
