NFS Network File System Howto

1. Install nfs packages
2. Alter /etc/exports
3. Restart nfs server
4. Mount on client

• Install nfs packages for Ubuntu/debian

  • sudo apt-get install nfs-kernel-server nfs-common portmap
    

  • Following install statements may be important:

    • Creating config file /etc/idmapd.conf with new version
      Creating config file /etc/default/nfs-common with new version
      Adding system user `statd' (UID 112) ...
      Adding new user `statd' (UID 112) with group `nogroup' ...
      ...
      Creating config file /etc/exports with new version
      Creating config file /etc/default/nfs-kernel-server with new version
      

• Add something like the following to /etc/exports . See here for more details
  • rw - read write access
  • async - double checks file writes, faster, riskier (can corrupt easier)
  • no_subtree_check - do not invoke subtree algorithm which verifies that a file that is requested from the client is in the appropriate part of the volume.

  • # raid5 lms (linux media server) share
    /media/documents   192.168.1.0/255.255.255.0(rw,async,no_subtree_check)
    

• Restart the nfs server

  • sudo /etc/init.d/nfs-kernel-server restart

• Update nfs file share lists

  • sudo exportfs -a

• Version and other info of running nfs’s

  • nfsstat

• Ctrl+K
• nfs://server.name/path/of/share

• mount -o -P lms:/media/documents /Volumes/lms

A built-in utility to OS X after Leopard that can keep track of mounts via a nice GUI.

• See http://zawaarudo.blogspot.com/2008/06/directory-utility-and-remote-nfs-mounts.html
• Automount Deprecated now that Directory Utility above does the same... easier

• See See http://ubuntuforums.org/showthread.php?p=4387032#post4387032 for some details

• mount master.foo.com:/home /mnt/home

• # device       mountpoint     fs-type     options      dump fsckorder
  ...
  master.foo.com:/home  /mnt    nfs          rw            0    0
  ...
  

• Syntax errors in /etc/exports
• options not correct in exports file
• uid / gid not matching on client and server
• little windows support
