No, there is a single version that we release for everyone. > What do you mean when you say "assist you more > effectively"?

The issue is that we are a company that is paying a lot of people to maintain and develop Lustre, and without paying customers none of this would get very far. It's great that we can give Lustre away freely for anyone, but the truth is that customers who are paying for support have priority in terms of getting attention to their bugs. In terms of how it can help Nikke to have support with CFS - it means we can afford to have someone smart like Alex on our staff to fix this problem in the first place. The fact that the fix in question didn't make it into 1.6.3 is an oversight on our part, as the patch was definitely ready in time for the release. We will of course include it in the next release, possibly making a point release with this fix sooner. > For a lot of very good reasons, we would like to go to lustre. > There is much to like about it.

I'm sorry to hear you are having problems, possibly the same ones being discussed here. As for OFED 1.2, this will also be available in the 1.4.12 release, if that is of interest to you, and of course we are working to address issues with 1.6 as well.
