Needed --no-autolabel to get it working. New ndctl didn't help. Which is nice as I didn't have to interrupt metadata operations of the servers with nvdimm's.

reconfigure namespace: No such device 2°) With 4.18.0-13 no active namespaces are seen which seems more coherent for non initialized NVDIMM-N with labels but no namespace can be created. Both patches (kernel & ndctl) listed in the github issue below needs to be applied in order to get them working properly. Tested against the current hwe 4.18 kernel. https://github.com/pmem/ndctl/issues/78 --- ProblemType: Bug AlsaDevices: total 0 crw-rw---- 1 root audio 116, 1 Jan 15 10:55 seq crw-rw---- 1 root audio 116, 33 Jan 15 10:55 timer AplayDevices: Error: [Errno 2] No such file or directory: 'aplay': 'aplay' ApportVersion: 2.20.9-0ubuntu7.5 Architecture: amd64 ArecordDevices: Error: [Errno 2] No such file or directory: 'arecord': 'arecord' AudioDevicesInUse: Error: command ['fuser', '-v', '/dev/snd/seq', '/dev/snd/timer'] failed with exit code 1: DistroRelease: Ubuntu 18.04 IwConfig: Error: [Errno 2] No such file or directory: 'iwconfig': 'iwconfig' MachineType: Dell Inc.
