Hi All,

We are in the process of transfering our fileservers to a new OS-version.

Installed latest OS 6.5 and the current Samba3-version, which is Samba 3.6.9.
Data folders are on XFS filesystem. Data folders are exported as NFS3-shares to an SSL-login server

Data folders are exported as Samba-shares to several different clients:
- windows7, ubuntu, SL6x, MacOSX

Now it seems that some of the windows7-clients see files as being read-only because they seem to be locked.
I've read a lot of different info about file locking in Samba, but information seems very confusing.

So,my question is, considering the environment of mixed clients over CIFS and NFS, what is the preferable Samba-setting for locks, Kernel_oplocks, Oplocks etc ?

If anyone has a lot of samba experience, please share your thoughts on this subject.

Regards,
Carel van der Werf
