Migrate images manually
This describes how to manually migrate an image or all images to another server.

Image files
Below, are many options for migrating an individual image. If you wanted to migrate all images, just change the source/destination paths in the below commands to /images Also, 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.
using lftp
lftp -c 'open x.x.x.x; user UserGoesHere PasswordHere; mirror -e /images/TheImagePath /images/TheImagePath; quit'
Example:
mkdir /images lftp -c 'open 10.0.0.4; user fog MyAwesomePassword; mirror -e /images /images; quit'
using NFS
mkdir /images mount x.x.x.x:/<remote source> <local mount point> cp -R /<local mount point>/* /<local destination> umount <local mount point>
Example:
mkdir /images 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 mkdir /images 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:
mkdir /images scp -r root@10.0.0.4:/images/* /images
Using rsync
rsync -a root@x.x.x.x:/images/* /images
Example:
mkdir /images 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.
