h/w: HP ProLiant Gen10 box with 4 nvdimms (16gb each)
# uname -aLinux fox22hv.lab.netapp.com 4.19.0-1.el7.elrepo.x86_64 #1 SMP Mon Oct 22 10:40:32 EDT 2018 x86_64 x86_64 x86_64 GNU/Linux
# ndctl --version
63+
Im not sure if I have label-less namespace or not. My intention was to play around with ndctl, destroy default 16gb namespaces and create some of my own. This may be due to user error or config error but I am not able to get past this. I have dug through every bit of info available online and have exhausted my options, hence this email.
I have not been able to destroy the default 16gb namespace. I get this error:
# ndctl destroy-namespace namespace0.0destroyed 0 namespaces
# ndctl destroy-namespace -f namespace0.0 -v

The semantics of destroy-namespace have certainly been cause of
confusion in the past - but my understanding is that HP nvdimms are
indeed label-less, and the namespaces on them can't be destroyed.
You should however be able to reconfigure them to use a different mode
using the create-namespace --reconfigure option.
