Can you post your findings in case others encounter the same issue? Thanks.

I saw the same message on real intel optane memory. After configuring pmem mode (from 'raw' to 'fsdax') with ndctl, the problem was resolved.
I'm try to install NOVA in my VMware Workstation,and I try to emulate Persistent Memory using DRAM,followinghttps://software.intel.com/en-us/articles/how-to-emulate-persistent-memory-on-an-intel-architecture-server.
I use linux-nova-master and configure kernel with CONFIG_LIBNVDIMM=y, CONFIG_BLK_DEV_PMEM=y, CONFIG_FS_DAX=y and CONFIG_NOVA_FS=y.
I successfully saw pmem0 in /dev/,and I can mount it without DAX. But when I run "mount -t NOVA -o init /dev/pmem0 /mnt/pmemdir",there is an error which is device does not support DAX.(when I use EXT4 with DAX,it said DAX unsupported by block device.)
I don't know how to solve it.Could you help me? Thank you very much!
