Solaris

I want to be able to mount 3 directories. But two are a subdirectories of the first.

/opt/gnu sunpefs02:/export/home/sunpefs02-5/replication/8600finland/gnu
/opt/gnu/bin sunpefs02:/export/home/sunpefs02-5/replication/8600finland/gnu/bin-sparc-SunOS
/opt/gnu/lib sunpefs02:/export/home/sunpefs02-5/replication/8600finland/gnu/lib-sparc-SunOS

The problem I have is, I can only get /opt/gnu to work by itself, or /opt/gnu/bin and /opt/gnu/lib by themselves.

When I put all three, I get an error starting up the automounter that says there is a hierarachical problem.

How do I get all three to mount?

Sun OS verison? kernel patch level?
uname -a
cat /etc/release
cat /etc/vfstab

This is the NFS rule...

We cannot export either a parent directory or a subdirectory of an already exported directory that resides within the same file system.If you intention is to export parent directory why do need one more export for directory which resided under parent directory?

I was trying to mimic how our overseas group mounted the paths to some GNU tools, because we are replicating the environment at our site.

I found syntax that allows me to do what seems like a hierarchical mount, but maybe it isn't quite.

The syntax in my "auto_gnu" file goes like this.

gnu <path to remote share> /bin <path to remote bin share> /lib <path to remote lib share>

This is ALL on the same line. And it works!

The reason WHY this was done is because /gnu is where the top level gnu tools are, and "bin" is just an empty folder to use as a mount point. What they did at our remote site was use these environment variable options like "$CPU" and "$ARCH" (something like that - Look it up, it is part of the automount docs) such that the automounter will mount the bin directory based on the cpu and architecture. So, if you login to a sparc, it automounts sparc-bin to /gnu/bin, if you login to linux, it automounts linux-bin to the /gun/bin directory. So the directory structure looks the same from all architectures, and the automounter is determing which platform bin directory to mount to /gnu/bin.

It is very convoluted. I mainly wanted to learn about the automounter and try to get this pseudo hierarchical mount working, which I did with the above syntax.

Thanks
