Change NFS location

This is not about a seperate NFS server in general, but about how to change the local storage directory and export it correctly.

As FOG sets the default location to /images in your / -partition you may want to have it in your /home-directory or partition.

You have to change these values and config files:


  • 1. Edit /var/www/fog/commons/config.php. (on centos 6 see /var/www/html/fog/commons/config.php)

Change the values of STORAGE_DATADIR and STORAGE_DATADIR_UPLOAD to

"/home/fog/images/"

and

"/home/fog/images/dev/"

for example.

If you already have created images with FOG, don't forget to move the complete directory /images to the new place. Be sure that the correct access rights are granted.


  • 2. Edit your exports file (in /etc/exports) to export the new location via NFS:

/home/fog/images *(ro,sync,no_wdelay,insecure_locks,no_root_squash,insecure)

/home/fog/images/dev *(rw,sync,no_wdelay,no_root_squash,insecure)

After that tell the running NFS-server to read the new config:

exportfs -a


  • 3. Edit your storage-node definition:

Go to Storage -> All storage nodes and edit the entry of the "Image Location:" to your new target for your Storage Node "DefaultMember".

After that your "Disk Information" (Free / Used / Total) at the dashboard may not be correct anymore. Edit the file freespace.php in your web-root (/var/www/fog/status/) (on centos 6 see /var/www/html/fog/status):

define( "SPACE_DEFAULT_STORAGE", "/home/fog/images/" );

You may also need to modify the permissions for the /home/fog directory. It is suggested that you use:

chmod 701 /home/fog


  • 4. Create .mntcheck file in your new "images" and "dev" folders :

touch .mntcheck


That's all!
