Setup a HIGH-AVAILABILITY environment using Ubuntu 12.04, MySQL, DRBD and Heartbeat
OpenNebula VM : Windows XP
OPENNEBULA 3.4.1 – LEARN TO SETUP HIGH-AVAILABILITY WITH UBUNTU 12.04 , MYSQL, DRBD and HEARTBEAT
Friends, this tutorial teaches you to setup a OpenNebula 3.4.1 HIGH-AVAILABILITY environment but with minimum hardware resources and some easy steps.
“High availability” refers to the practice of keeping online resources available through node failure or system maintenance.
I am using just 2 VT enabled Intel Xeon Servers and a normal Intel dual core Windows XP laptop with 2GB Ram for having remote sessions and VSphere client.
MySQL,DRBD and Heartbeat packages already available with Ubuntu 12.04 will be used, so that installation and setup will be a bit easy.
Hope you may like it
regards
Anil

Hello Sir,
When i put this following command it show like this..
command: drbdadm create-md r0
result: ‘r0’ ignored, since this host (server-one) is not mentioned with an ‘on’ keyword.
And Just i show the following command output:
root@server-one:/# drbdadm up all
WARN: no normal resources defined for this host (server-one)!?
root@server-one:/# cat /proc/drbd

root@server-one:/# drbdadm disconnect r0
‘r0’ ignored, since this host (server-one) is not mentioned with an ‘on’ keyword.
