NFSv4 (BASIC features)

We will configure server-03 to export user files and directories (/export/home) and the directory “scratch” (/export/scratch)

1. Pre-Installation:

   • Check the current kernel supports NFSv4.

   • Copy the full content of user’s homes created in Lab1 (LDAP) from frontend:/home/ to server-03:/export/home/. Also, check the access to the users' home and their ownership permissions are ok (0700)

2. Installation: (1)

   • NFS server (nfs-kernel-server)

   • NFS support files common to client and server (nfs-common)

3. NFS configuration:

   • Enable IDMAPD for LDAP integracion in user/group <--> ID/GID mapping

     • IDMAPD domain: localdomain.

   • Table of exported NFS file systems:

     • Exported directories:

       1. /export/scratch

       2. /export/home

     • All our exported FS will be located in /export

       1. Counfigure /export as “root” directory of our table of exported NFS file systems (pseudo-fileystem hierarchy).

     • Export options:

       1. Access mode: rw

       2. Syncronization mode: async

4. Checking (on server-03):

   • Create a temporary directory: /tmp/nfs

   • Using NFS, mount the NFS file system home on the temporary folder.

   • Make sure everything is ok (NFS mounting)

   • Unmount the NFS file system and remove the temporary folder.
