Hi all,

I'm using optane device on linux machine

when i type pmempool create at mounted directory, my machine shows following lines

#pmempool create blk 512 test.pool

error: 'test.pool' -- ndctl_dimm_get_dirty_shutdown: No such file or directory

error: creating pool file failed

there was no error message when i create namespace and mount pmem devices.

version of tools

ndctl - 68

pmempool - 1.8

these are ndctl list lines

#ndctl list

[

{

"dev":"namespace0.0",

"mode":"fsdax",

"map":"dev",

"size":266352984064,

"sector_size":512,

"align":2097152,

"blockdev":"pmem0"

}

]

if you need more information, please let me know.
