perfSONAR User Q&A and Other Discussion

[Zhi-Wei Lu <>]

Hi all,

 

I would like to replace one of our new perfsonar node from the new test IP to the existing production IP. 

I plan to do the following:

 

1.      Prepare new ip/hostname ssh host-keys for both hosts (swap) not activated yet

2.      Updating both systems and reboot

3.      Switch  into single user mode (/sbin/init 1) and start network (I can do this in an IPMI console)

4.      Save /opt/esmond, /opt/perfsonar_ps, and /opt/rh, /var/lib/pgsql, on both servers

5.      Copy (exchange) data from both servers

6.      Shutdown the network, swap cables and activate new network for both servers

7.      Reboot both servers

 

Is there anything that I miss or overlook?  Thank you for your help.
