Bad (none) permissions on files and directories created with cifs

MZa — Wed, 04 Jun 2025 09:52:07 GMT

I have cifs/nfs share on volume with security style unix. If the file (or directory) is created with CIFS it has set permissions to "000"

ll /netapp/upload/users/zacekm/
d---------. 2 zacekm zacekm 4096 Mar 8 09:24 d1
drwxr-xr-x. 2 zacekm zacekm 4096 Mar 8 09:25 d2

The d1 dir is created with nfs, the d2 dir with cifs. The umask of the share is set to 0. Is there any option similar to "force create mode" on Samba share? I need at least 700 for dirs and 600 for files.

Thanks

Please check these..

Under UNIX security style, a file or directory can be accessed or modified by the superuser (typically uid 0), owner, or a group of users who have been given permission to do so.

I can change the permissions of existing files and directories from the Linux client, but I need the newly created files and directories to have some reasonable permissions set automatically, such as 750 for directories and 640 for files. Is there an option in NetApp similar to samba's "force create mode"?
