The only problem is that oplocks sometimes give you trouble. Not just oplocks (which must be turned off, because they can't be forwarded by NFS to the source server, so risk parallel writers), but other byte range locks, if you where expecting these to be honoured back to the source NFS server.

Actually, byte range locks should work over NFS. That's not to say they *do*, but there's an extension to the core protocol that supports them (although not all NFS servers support it).

By my experience, it is possible but I had to turn off this setup because we had issues with MS Office files. The oplock wasn't working correctly and we had problems with saving MS Excel files on this share. It was also not easy to tune the performance, the samba share had a tendency to lag when we where browsing it or when we where opening files.

We have an NFS filer right now that we need to provide our windows users access too. For various reasons they won't use SFU, etc. In our legacy environment we have a file server that does NFS/CIFS natively. In our new environment not so much. We want to provide this service to our users and the solution proposed to me is to utilize SAMBA as the mechanism to do so. After doing exhaustive googling and searching I can't seem to find if this is doable, and if it is what kind of things I should be on the lookout for, or configuring the system for. So first, is it possible? Second, if it is possible is it just a matter of mounting the NFS volume on the SAMBA server and then re-exporting to the Windows clients?
