Yes I have seen projects canned due to lack of NFS in a zone. Most recent one was where they wanted to consolidate their dev environments in one server and allow each dev department to have full root access to their container only and no access to any other part of the machine. This could not work without NFS functionality
in the container.

It would be really nice if we could go beyond just NFS. Imagine being able to run Oracle RAC across containers. That would give us some real cool things indeed.

This has been a major complaint for many sysadmins and beta testers. I
know one of my first bugs filed against the betas of Solaris 10 was the
lack of NFS server functionality within zones. I've even been in the
situation at work where this has been a requirement, only to have to
scrap projects. Probably the most common idea for having a zone NFS
server is for Jumpstart or home directories. As things stand today,
it's not doable. I've even escalated this thru different channels over
the past few years only to see it go no where. I'm sure there is a lot
of demand for this feature for zones.

I think the key requirements would be:

1. Full NFS server functionality within a zone. So things like share,
/etc/dfs/dfstab, sharemgr, ZFS sharing, etc. should work in the same
manner as they do in the global zone.
2. Security. Separation of NFS namespace to insure proper security
between zones. This may be achieved by making the kernel NFS framework
aware of the zoneid context.
3. Performance. NFS serving out of a zone should not be slower or less
scalable than NFS serving from the global zone.

Starting a project would be nice. But I think there should be close
involvement with the NFS engineers at Sun. As for getting their
attention and funding, the best we can do is show enough community
interest for NFS within zones.

So I'd ask all sysadmins, developers, etc. to respond to this thread to
show support for fixing this.

I look at the first hurdle and see a golden opportunity for a real OpenSolaris project -
since internal developers aren't scheduled to do this work, we can
get external
developers involved from the start of the project.

Of course, the second hurdle really stops us from kicking off the

I'll start the ball rolling by kicking in some thoughts that Spencer

We should define the requirements as a community and then get the
started in that community.
