Hi Vishal Verma, Now there is an urgent issue from Alibaba - AEP namespace disable&destroy issue https://hsdes.intel.com/appstore/article/#/22012576039. Here attached the log of ndctl cmd and you can find several error prompting info inside. You can see it fails to recreate namespace again after destroying the namespace with mode being devdax. ]0;root@cloud-dev-benz: ~root@cloud-dev-benz:~# ndctl create-namespace -r region0 --mode=devdax libndctl: ndctl_dax_enable: dax0.1: failed to enable Error: namespace0.0: failed to enable Can you please help to check with priority as it blocks Alibaba's deployment? Many thanks, Chunye
