Secondly, if you absolutely must do it, I recommend the following settings: [global] # your other options here... oplocks = No level2 oplocks = No On certain shares, you may want to set: posix locking = No Ray -- To unsubscribe from this list go to the following URL and read the instructions: https://lists.samba.org/mailman/options/samba

Running Samba on NFS imports is a really bad idea. At least every month people report strange lockups, timeouts and other weird things on this list that can be attributed to NFS imports. You should really contact SUN for information how to log into that box and install Samba. Volker
From: Nicholas Brealey on 23 Jan 2010 08:30 The Sun 7310 is a storage appliance. It is not running Solaris 10 but runs an OS based on Open Solaris with CIFS and Windows style authentication integrated in the kernel. Installing Samba is not an option. You really should be using the integrated CIFs server. It is probably simpler to set up than Samba but is probably not as flexible (has fewer configuration options). There is a simulator you can play with to learn how to set it up. Sun offer courses on setting it up. Sun offer a service to set it up for you. The manual is available on the Internet or from the storage device. There is a forum where these devices are discussed. You almost certainly got a support contract when you bough the device. If you cannot use its CIFS server (ie if you are using a NT 4 style domain or a Samba PDC) perhaps using iSCSI to the Linux box and sharing with Samba is the next best option.

Mostly it is locking problems. Some daemons not started, daemons not 100% working right, etc. Then it is also a big performance drain. Sending data over the net twice without proper caching is really subobptimal. Then, potentially not all features fully supported (EAs, ACLs, etc). This is just a pain in the neck. And, for us here on this list it is a pain because all those problems show up for the Samba clients, so by definition those bugs appear to be Samba bugs while they are NFS problems.

I'm not doubting that what you say is true, since I've seen it myself, but whenever possible I try to get deeper understanding of what causes these strange problems. That's one of the reasons why I posted my question. So, I'll restate the question - what is it about NFS exports that gives Samba trouble that doesn't occur when serving local files?
