After you've installed and configured your stoney cloud Test-Environment, but before you've added any profiles, you need to make a complete Backup of your LDAP directory:
<source lang="bash">
/usr/sbin/makeOpenLDAPmasterBackup.sh
</source>
The output will look something like:
<source lang="bash">
Backup directory /var/backup/ldap/vm-test-01.int.stoney-cloud.org exists

You can look at the backup file with:
vi /var/backup/ldap/vm-test-01.int.stoney-cloud.org/OpenLDAPmasterBackup.ldif.2015-02-12
</source>
Copy the newly created OpenLDAPmasterBackup.ldif.2015-02-12 to another location for later use:
<source lang="bash">
mkdir -p /root/stoney-cloud-reset
cp /var/backup/ldap/vm-test-01.int.stoney-cloud.org/OpenLDAPmasterBackup.ldif.2015-02-12 /root/stoney-cloud-reset/.
</source>
= Resetting your Test-Environment =
== Stop the Web Server ==
Stop the Web server on both Master-Nodes:
<source lang="bash">
/etc/init.d/apache2 stop
</source>
== Stop the LDAP Server ==
Stop the LDAP server on both Master-Nodes:
<source lang="bash">
/etc/init.d/slapd stop
</source>
== Remove all unnecessary Files ==
Remove all the unnecessary files on the Primary-Master-Node:
<source lang="bash">
rm /var/virtualization/iso-choosable/*.iso
rm /var/virtualization/iso/*.iso
rm /var/virtualization/vm-templates/*/*.qcow2
rm /var/virtualization/vm-dynamic/*/*.qcow2
rm /var/virtualization/vm-persistent/*/*.qcow2
</source>
== Clean up the Firewall Rules ==
If you have configured the automatic firewall rules creation, you need to execute the following commands on the Primary-Master-Node:
<source lang="bash">
svn up /usr/local/scripts/netfilter/local/chains/vms
svn rm /usr/local/scripts/netfilter/local/chains/vms/*
svn ci -m "Removed all test VM rules" /usr/local/scripts/netfilter/local/chains/vms/
</source>
On the Secondary-Master-Node and all other VM-Nodes, you'll need to execute:
<source lang="bash">
svn up /usr/local/scripts/netfilter/local/chains/vms/
</source>
== Remove libvirtd State ==
We need to remove all existing libvirtd states on all Master-Nodes and normal VM-Nodes:
<source lang="bash">
/etc/init.d/libvirtd stop
rm /etc/libvirt/qemu/*.xml
rm /var/lib/libvirt/qemu/channel/target/*
/etc/init.d/libvirtd start
</source>
== Reset the LDAP Server ==
Now you reset the LDAP server with the the previously created backup:
<source lang="bash">
cp /root/stoney-cloud-reset/OpenLDAPmasterBackup.ldif.2015-02-12 /var/backup/ldap/vm-test-01.int.stoney-cloud.org/.
/usr/sbin/restoreOpenLDAPmaster.sh
</source>
You'll be led through the restore process:
<source lang="bash">

Please enter the date of the backup to restore in the form of YYYY-DD-MM (for example: 2007-10-15):
2015-02-12
</source>
The LDAP server has now been restored to the state from 2015-02-12, the indices have been created and the LDAP server has been started.
== Start the Web Server ==
Start the Web server on the Primary-Master-Nodes:
<source lang="bash">
/etc/init.d/apache2 start
</source>
