[lustre-discuss] lnet router lustre rpm compatibility

[Jessica Otey]

All,
I am in the process of preparing to upgrade a production lustre system 
running 1.8.9 to 2.4.3.
This current system has 2 lnet routers.
Our plan is to perform the upgrade in 2 stages:
1) Upgrade the MDS and OSSes to 2.4.3, leaving clients in 1.8.9.
2) Upgrade all clients to 2.4.3 (thus allowing the entire system to be 
subsequently updated to 2.5 and beyond)

The problem is that I can't seem to locate any information about the 
version requirements (if any) for lnet routers. Does the lnet router 
have to be the same as mds, or the same as the clients? Or both?

Any light shed on this would be most helpful.

Thanks,
Jessica
