samba failing to start after centos7.2(rhel7.2) update

환경 : CentOS-7.2 (64bit)

 

증상

얼마전 제공된 centos-7.2 업데이트 이후 갑자기 samba 구동이 되지 않음

# systemctl start smb
Job for smb.service failed because the control process exited with error code. See "systemctl status smb.service" and "journalctl -xe" for details.

???? 사실 이 때 까지만 해도 7.2업데이트(정확히는 samba 업데이트) 때문에 발생한 문제 라는 것을 몰랐음.

7.2 업데이트시 samba 버전이

기존 : 4.1.12
변경 : 4.2.3

으로 변경되는 내용이 있었고..

버전 변경에 따라 설정 파라미터 역시 영향을 받았다는..

 

해당 옵션은 그냥 삭제… ;;;;

아직 업데이트 된 버전의 설정값을 제대로 확인하지 못함…
