Change NFS location

Wise: /* Change NFS location */ updated directory paths to .php files for centos 6 and likely other distro

=== 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!

Upgrading the FOG Server

Wise: Added note about the location of installation option values, wasted a bunch of time because I couldn't find the file

== Upgrading the FOG Server ==

'''It is highly recommended that you backup your data before you perform the upgrade.'''

Upgrading from one version of FOG to a newer version is as easy as running the installer for the new version of FOG. It will update your system while leaving your data in place.

Remember install settings are in <install directory>/fog/.fogsettings. If anything has changed since the last install make updates to .fosettings before running the install.

FOG will '''NOT''' modify:

*Any modified reports
*Image Files
*All database settings

FOG '''WILL''' modify:

*Any Custom changes to php/init.gz file.
*Any changes to dhcpd.conf.
*Any changes to /etc/xinetd.d/tftp.
*Any changes to /etc/vsftpd/vsftpd.conf.
*Any changes to /etc/exports.
*Any changes to php config files on /var/www/fog and /opt/fog
