There are 3 NVM files here, NBTree, Dash and Falcon, which NVM file can not open and is the path correct?
After I run ycsb.sh with root, it shows:
running 1 test
creating a new pool
pool opened at: 0x5f0000000000
/mnt/pmem0/pmem_btree.data
[NVM MGR] failed to open nvm file
error: test failed, to rerun pass --lib
The path is correct since it has the pmem_hash.data file.
It seems to be a problem with NBTree. It may be necessary to create the file in advance.
I don't have an experimental environment at the moment and I'll try it later. You can use "printf("errno=%d\n",errno);" on NBTree/tree/src/btree.cpp line 52 for more detail
When I create the file in advance, I can open the file. However, I still run this project. Seems to be a problem with NBtree.
The problem is following:

It reports that "Is a directory". Is the path on src/customer_config.rs(line3) is a directory? It should be the path of a file in NVM
I run this project successfully. This is a very good project and worthwhile for people on the topic of OLTP transactions on NVM. I suggest you modify README.md to make it easier for the programmer behind you to run it directly. The subprojects of a project cannot be downloaded automatically via git pull --recurse-submodules. The pmem_btree.data file needs to be created manually. The other can be created automatically.
Thank you.
When I ran this project, I found the project report the error. I use the root account, and run sh ycsb.sh.
