@sscargal Can you help me look at this?
@yanglongkanglo Can you describe your environment please?
Q) What Operating System do you have installed? (cat /etc/os-release
)
Q) Is this a bare-metal, Virtual Machine, or Container environment?
Q) Do you have physical PMem installed, or are you emulating it with QEMU or the Kernel memmap option?
Q) What regions do you have? (ndctl list -R
)
Q) What active/inactive namespaces do you have? (ndctl list -Ni
)
Q) If you have physical Intel Optane [100|200] PMem installed, can you collect ipmctl show -dimm
, ipmctl show -region
, ipmctl show -memoryresources
Q) What do you see in dmesg or /var/log/messages around the time you ran the ndctl create-namespace -m devdax -a 2M -r region0
command?
Q) What do you see if you add the --verbose
(-v) option to the ndctl create-namespace -m devdax -a 2M -r region0
command? ie: ndctl create-namespace -m devdax -a 2M -r region0 --verbose
Also please try with current version.
