MTU change

Hello Admin,

 

Is there a way to change the MTU from 1500 to 9000 after installation, I have setup 4 servers and I need to change the MTU on these nodes while running.

 

Thanks

You need  to edit the /opt/petasan/config/cluster_info.json  on all nodes and add the list of interfaces needing jumbo frames to the "jumbo_frames": [] array. This needs to be done on all nodes then reboot. The syntax is very easy json, or it may be easier for you to create a vm and install PetaSAN on it and deploy it to create a new cluster with the desired network setup then grab its conf file.
