OK, I now have a single node up and running as per the instructions 
provided by Ronnie. I just have a few questions:

there is this in the ctdb log

2014/12/13 11:52:43.522708 [ 5740]: Set runstate to INIT (1)
2014/12/13 11:52:43.540992 [ 5740]: 00.ctdb: awk: line 2: function

2014/12/13 11:52:56.931393 [recoverd: 5887]: We are still serving a 
public IP '127.0.0.3' that we should not be serving. Removing it
2014/12/13 11:52:56.931536 [ 5740]: Could not find which interface the 
ip address is hosted on. can not release it
2014/12/13 11:52:56.931648 [recoverd: 5887]: We are still serving a 
public IP '127.0.0.2' that we should not be serving. Removing it

The above three lines are there 4 times

the final 4 lines are:

2014/12/13 11:53:02.982441 [ 5740]: monitor event OK - node re-enabled
2014/12/13 11:53:02.982480 [ 5740]: Node became HEALTHY. Ask recovery 
master 0 to perform ip reallocation

now 0x0  was 0x2

2014/12/13 11:53:03.046859 [recoverd: 5887]: Takeover run completed 
successfully

ctdb status shows:

Number of nodes:1
pnn:0 127.0.0.1        OK (THIS NODE)
Generation:740799152
Size:1
hash:0 lmaster:0
Recovery mode:NORMAL (0)
Recovery master:0

So, how do I get rid of the 'awk' error lines ? Why shouldn't the public 
IP lines be served ?

Now I know it works, I just have to pull it all together.
