Create Namespaces with ndctl
Follow the instructions below to properly create namespaces using the ndctl commands:
•
ndctl create-namespace [--mode | fsdax, sector]
•
Example: ndctl create-namespace --mode fsdax
•
Repeat the same step to create a namespace for each region
Check if Namespace is Successfully Created
To check if the namespace is successfully created, please use the ndctl command below:
•
Is -l /dev/ | grep pmem
M.2. Check if Namespace Successfully Created
List Active Namespaces
Use the ndctl list -N command to display the active namespaces list.
Delete Configuration
Deleting the current configuration can be done in two steps. First, namespaces need to
be disabled and destroyed. After successfully destroying namespaces, disable the active
regions to delete the configuration.
Disable Namespace
Use the ndctl disable-namespace X command to disable the namespace of the user's
choice. X represents the namespace on the active namespaces list.
Note: It is imperative to stop applications and unmount used namespaces before
disabling the namespace.
