Migrate images manually

This describes how to manually migrate all images to a new server.

Image files

Below, are many options for migrating all images. This article assumes you have FOG installed already on the new server, because the installer would setup FTP and NFS for you. Fog doesn't setup Samba but an example of how to use a Samba share is included. Where you see x.x.x.x, this is the old storage node's IP address. These commands are written to be run on the new storage node, however they can be altered to run on the old storage node.

using lftp

lftp -c 'open x.x.x.x; user UserGoesHere PasswordHere; mirror -e /images/TheImagePath /images/TheImagePath; quit'

Example:

lftp -c 'open 10.0.0.4; user fog MyAwesomePassword; mirror -e /images /images; quit'

using NFS

mount x.x.x.x:/<remote source> <local mount point>
cp -R /<local mount point>/* /<local destination>
umount <local mount point>

Example:

mkdir /tempMount
mount 10.0.0.4:/images /tempMount
cp -R /tempMount/* /images
umount /tempMount

Using Samba

mkdir /LocalMountPointHere
mount -t cifs //x.x.x.x/ShareNameGoesHere /LocalMountPointHere -o username=YourUsernameGoesHere -o password=YourPasswordGoesHere,noexec
cp -r /LocalMountPointHere/* /DestinationHere
umount /LocalMountPointHere

Example:

mkdir /tempMount
mount -t cifs //10.0.0.4/images /tempMount -o username=root -o password=MyAwesomePassword,noexec
cp -r /tempMount/* /images
umount /tempMount

Using SCP

scp -r root@x.x.x.x:/images/* /images

Example:

scp -r root@10.0.0.4:/images/* /images

Using rsync

rsync -a root@x.x.x.x:/images/* /images

Example:

rsync -a root@10.0.0.4:/images* /images

Image Definitions

Image definitions are what's stored in the database, and what is displayed in the web interface. There are DB entries for each image. Image definitions do not automatically appear just because the image files are present on the storage node, this is a common misconception.

You may recreate these manually, but you must recreate them exactly as they were on the old server. The image path must be exact and is case sensitive, the image OS and image type must be set exactly as in the old server as well.

The easiest option is to use FOG's export/import feature inside of Image Management.
