Hi all, Have we decided what to do for supporting NFS server in non-global zones??
And if we are going forward with the kernel approach (instead of running user-space NFS servers), then may be the NFS developers can answer a few questions: 1) How big a project is it?? (just a rough est) 2) Where is the code for the NFS service?? Which source directory(s) is the starting point?? Correct me if I am wrong - what we need to do to let non-global zones be NFS server is to change some of the data structures in the NFS server code to per-zone data structure - similar to IP Instances: "... take all the other data and convert it from global data to fields in an instance data structure" page 21: http://www.opensolaris.org/os/project/crossbow/Docs/ipinstances-sug1.pdf And, if this is not many months of work, then sounds like it can be a summer of code project, and I will write up an initial project proposal (similar to what I am going to do for "lx brand on SPARC (Project BrandZ)" ): http://mail.opensolaris.org/pipermail/summerofcode/2007-March/000011.html Rayson On 2/14/07, Octave Orgeron <[EMAIL PROTECTED]> wrote:
Hi Tom, Thanks for the input. I agree that it'll take a lot of involvement from the community to deliver the code. But I also think there some should a lot of collaboration with the NFS engineers to insure we don't break stuff:) I'm all for a project to be launched from the NFS or Zones community for this. I'd even be willing to help out, just have to keep in mind my programming is a little rusty:) Octave --- Tom Haynes <[EMAIL PROTECTED]> wrote: > Octave Orgeron wrote: > > Hi, > > > > This has been a major complaint for many sysadmins and beta > testers.
