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}}
