stoney cloud: Resetting your Test-Environment

Overview

This page describes how to easily reset your stoney cloud Test-Environment.

Prerequisites

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:

/usr/sbin/makeOpenLDAPmasterBackup.sh

The output will look something like:

Backup directory /var/backup/ldap/vm-test-01.int.stoney-cloud.org exists
###################################################################################################

Removing backups older than 15 days ...
###################################################################################################
find /var/backup/ldap/vm-test-01.int.stoney-cloud.org -type f -ctime +15 -exec rm {} \; >/dev/null

Backup Started
###################################################################################################

Executing touch /var/backup/ldap/vm-test-01.int.stoney-cloud.org/OpenLDAPmasterBackup.ldif.2015-02-12
###################################################################################################

Executing chmod 600 /var/backup/ldap/vm-test-01.int.stoney-cloud.org/OpenLDAPmasterBackup.ldif.2015-02-12
###################################################################################################

Executing /usr/sbin/slapcat -l /var/backup/ldap/vm-test-01.int.stoney-cloud.org/OpenLDAPmasterBackup.ldif.2015-02-12
###################################################################################################

Backup Finished
###################################################################################################

You can look at the backup file with:
vi /var/backup/ldap/vm-test-01.int.stoney-cloud.org/OpenLDAPmasterBackup.ldif.2015-02-12

Copy the newly created OpenLDAPmasterBackup.ldif.2015-02-12 to another location for later use:

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/.

Resetting your Test-Environment

Stop the Web Server

Stop the Web server on both Master-Nodes:

/etc/init.d/apache2 stop

Stop the LDAP Server

Stop the LDAP server on both Master-Nodes:

/etc/init.d/slapd stop

Remove all unnecessary Files

Remove all the unnecessary files on the Primary-Master-Node:

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

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:

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/

On the Secondary-Master-Node and all other VM-Nodes, you'll need to execute:

svn up /usr/local/scripts/netfilter/local/chains/vms/

Reset the LDAP Server

Now you reset the LDAP server with the the previously created backup:
