I’ve been getting our Solaris environment setup in the College of Architecture, and one of the things I quickly realized with zones is that I’m going to need to setup LDAP to have any sort of efficient way of managing user accounts. Once this was setup, I quickly realized the need for NFS to be setup and thought that it’d be fairly straight-forward to setup (like it is on Linux). This turned out to not be the case.

I followed the instructions on several different sites, including sites talking about setting up Solaris Jumpstart servers. One of the first things I realized was that I needed to get a copy of the Solaris 10 software so I can install packages. We were lucky enough to have friends over in the Department of Computer Science use their jumpstart servers to setup our servers, so I didn’t quite have media available.

I went on Sun’s web site, downloaded the DVD and burned it to disk. Then I found out that some of the automounting functions on our Solaris boxes were not installed, thus forcing me to go through the rigarmarole of trying to mount a DVD to be able to access it. In short, the command is:

mount -F hsfs /dev/dsk/c0t0d0s2 /mountpoint

Note that -F hsfs is required for it to mount right. The actual disk (in my case, /dev/dsk/c0t0d0s2) will differ from server to server, but you can find where your DVD drive is located by using:

:: iostat -En

You can see my DVD drive based on the output above.

Anywho, once it was mounted up, I followed the instructions to install the following packages:

SUNWnfssu     Network File System (NFS) server support (Usr)
SUNWnfssr     Network File System (NFS) server support (Root)
SUNWnfsskr    Network File System (NFS) server kernel support (Root)

But, when this was installed and I setup my dfstab correctly, when I did shareall, I still got the following error message:

:: shareall
share_nfs: /home: Unknown error

I scratched my head, and Google yielded no valuable answers for me because it is obviously a vague error message. Only when I actually when to the server console (or checked /var/adm/messages) did I find out what was going wrong:

May 29 12:05:00 sql3 genunix: [ID 819705 kern.notice] /kernel/misc/nfssrv: undefined symbol
May 29 12:05:00 sql3 genunix: [ID 826211 kern.notice]  'nfs_getflabel'

May 29 12:05:00 sql3 genunix: [ID 472681 kern.notice] WARNING: mod_load: cannot load module 'nfssrv'

Googling these error messages yielded no answer, solution, or even indicated that someone out there may have the same problem as me. When I consulted with the guys in Computer Science, they indicated that they were using Solaris 10 revision 4, not revision 5. Given the date that I downloaded the software (approximately May 27th), I quickly realized that I have revision 5. They sent me over the software for revision 4, I uninstalled the packages above and installed the older packages, and everything worked just peachy. :-)
