I do know how to login to this box, but that's only because a Sun support person told me how. This was necessary to fix a non-Samba related problem. It sure looks like Solaris to me. In any case, I had to promise I wouldn't make any changes that weren't authorized by Sun. I intend on keeping this promise. Installing Samba is not an option. I agree 100%. 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). I'm not sure how simple it is to setup. For example, I couldn't even figure out what share name it generates. Although the performance and price of the 7310 are excellent, its documentation is not. There is a simulator you can play with to learn how to set it up. I know. I used it when I was deciding whether to buy the 7310. The manual is available on the Internet or from the storage device. The manual is just the help system on the device, as you say. It says very little about how to set up CIFS shares. There is a forum where these devices are discussed. You almost certainly got a support contract when you bough the device. I didn't know about a support forum. I'll check into that. I do have a support contract but if it's necessary to call support for something as simple as this, then somebody has blown it - either Sun or me. 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. None of these apply. Besides, I'd still like to understand the fundamental issue, which is why Samba behaves differently when it server NFS mounts than it does when it serves local files. http://forums.sun.com/forum.jspa?forumID=831 I'll check there.

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?

However, I still can't say that I understand its fundamental cause. Here's my current understanding. Assuming that network bandwidth isn't an issue, which it isn't in my case, then, the lockups, timeouts, and other weird things that occur must be because related to how Samba emulates Windows' locking behavior on top of NFS mounts, which have their own locking semantics. Although I'd be the first to admit that what I'm doing isn't very common, and probably doesn't deserve much, if any, attention from the Samba developers, I think that this should work - at least it should work better than it currently does. 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 These settings seem to do the trick. I sincerely appreciate the comments that I received on this issue. I hope bring this up helps other people facing this problem, if any.

Hallo, Jon, Du meintest am 25.01.10: First of all, you really don't want to re-export NFS mounts via Samba. I can't argue with this since I've felt the pain. I have tried it (NFS mount as share). Sometimes it run, sometimes it creeped, sometimes it was dead. All oplocks were set as recommended - wasn't enough to cure the system. Mounting per cifs: no more problems. Viele Gruesse!

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.
