Is it possible and supported to force MTU to 1500 on HA interface

Antonio Trigo

Hello,

I have an A/A cluster connected to a virtual switch on Hyper V cluster.

When I try to put master and slave on different Hyper V cluster nodes, several warnings appear on HA log.

"Lost heartbeat message from node 1! Expected xxx"

After looking at several KBs I found this one:

This would be possible to implement on a physical environment, but not on virtual.

Is it possible to force MTU to 1500 on HA interface of UTM and be supported?

How can I achieve this?

Thank you.

    Olá Antonio and welcome to the UTM Community!

    As root at the command line:

    cc set ha advanced mtu 1500

    You will also need to do ha_utils ssh and become root on the Slave node so that you can set the MTU there also.

    2000 is preferred, but I don't know how to make changes in Hyper-V.

    Cheers - Bob
