CIFS - NFS file sharing

Hi Guys,

Currently running into some issues with a CIFS-NFS mixed environment, and was wondering if anyone can share some wisdom on how to do it.

What we are trying to do:

• Use CIFS and NFS together for one filesystem
• From CIFS, many different users will write to the NAS
• From NFS, only 1 user will write to the NAS

  

What we have done is: 

• EMC NAS (NS-G8) on 6.0 code.
• Filesystem mounted in “NATIVE” mode
• Filesystem is shared in CIFS, with umask 002, so
  in the Celerra new files will have rw-rw----  Unix permissions, to allow
  files to be written by group
• On the root of the filesystem, we have setgid
  set against the group for the users, so the permissions will be propagated.

Does this sound right?

Thanks,
Kelvin
