How can you rename a loadbalancer

terryls · 09-30-2014, 09:19 AM

Greetings
I have 2 LVS load balancers and cloned the drive of one. The 2nd system is developing drive failure. What are the steps to rename the cloned system to replace the failing machine?

In other words: LB1 drive was cloned. LB2 is now failing. How do I rename the cloned LB1 drive now in an identical computer to LB2 and replace the now failing LB2 with the cloned LB1 computer renamed to LB2? I don't want to attempt to clone the failing drive. Thank you
Ubuntu 10.04

A start is to find all config files that contain the name:

Code:

find /etc -type f -exec grep -Hi lb1 \{} \;

You'll probably get some false positives due to the short names. You usually have to change 5 or 6 places depending on what's installed. I don't know how you would do this once systemd takes over and converts everything to binary files.

Thank you for your response.
It seems the command either has an issue or I'm interpreting
the line literally and need to change something.

from a sudo prompt: find /etc -type f -exec grep -Hi lb1 \{} \;

returns the following:

missing argument to '-exec'
No command 'lb1' found

Thanks again for your help.

I was right.
My literal input needed to be the actual name of the existing server, not my example of lb1.
After I changed the command from lb1 to the server name, I found several entries.
Now to start looking for what to change.
Thanks again!!
