Prepare to Upgrade Abiquo

1. Prevent cloud users from performing VM operations

• In the UI Infrastructure tab, select each physical machine and click Disable
• Using the API, set the state of each physical machine to DISABLED

2. Check for operations in progress on the platform

1. Check that the Abiquo RabbitMQ queues are empty. The number of messages in all queues must be 0:
   
   

   # rabbitmqctl list_queues messages name
   Listing queues ...
   0	abiquo.am.notifications
   0	abiquo.bpm.notifications
   0	abiquo.datacenter.requests.ADatacenter.bpm
   0	abiquo.datacenter.requests.ADatacenter.virtualfactory
   0	abiquo.ha.tasks
   0	abiquo.nodecollector.notifications
   0	abiquo.pcrsync.messages
   0	abiquo.pcrsync.parking-expect-no-consumers
   0	abiquo.scheduler.fast.requests
   0	abiquo.scheduler.requests
   0	abiquo.scheduler.slow.requests
   0	abiquo.tracer.traces
   0	abiquo.virtualfactory.notifications
   0	abiquo.virtualmachines.definitionsyncs
   0	abiquo.vsm.eventsynk
   ...done.

   On standard environment, the RabbitMQ service is in the Abiquo API server. Depending on the environment, this will be the Abiquo Monolithic or the Abiquo Server appliance.

   
   
   

2. Check for any active V2V conversions by checking for the V2V or Mechadora processes

   $ ps aux | grep v2v
   $ ps aux | grep mechadora

3. Stop platform services

1. Abiquo Server

   service abiquo-tomcat stop
   service httpd stop

2. Remote Services

   service abiquo-tomcat stop

3. V2V Server
   
   1. The BPM remote service is run on-demand only, so there is no need to stop anything
   
   
   

4. Monitoring server

   sudo service abiquo-delorean stop
   sudo service abiquo-emmett stop
   sudo service kairosdb stop
   sudo service cassandra stop

5. KVM hypervisor

   service abiquo-aim stop

6. LVM persistent storage server

   service abiquo-lvmiscsi stop

4. Back up the main platform elements

1. Back up the Abiquo MySQL DBs with the date in timestamp format.

   mysqldump --routines --triggers kinton            > kinton.sql-$(date +%Y%m%d_%H%M%S)
   mysqldump --routines --triggers kinton_accounting > kinton_accounting.sql-$(date +%Y%m%d_%H%M%S)

2. Dump the redis datastore and back it up.

   redis-cli save
   cp -a /var/lib/redis /var/lib/redis-$(date +%Y%m%d_%H%M%S)
   

3. Back up /opt/abiquo folder on all Abiquo platform servers.

   tar cvfz /opt/abiquo.tgz-$(date +%Y%m%d_%H%M%S) /opt/abiquo

4. Back up the UI including configuration and custom language files

   tar cvfz /var/www/html/ui.tgz-$(date +%Y%m%d_%H%M%S) /var/www/html/ui
