Hey Lustre fans!

Is there anyone out there running Lustre server version 2.5.x with a Lustre client version 2.11.x? I'm curious if you are running this combination and whether or not you saw and gains or losses when you went to the newer Lustre client.

We were running Lustre 2.7 client before and just recently went to 2.11. I'm trying to get a better understanding as to how common it is to have the version drift between the server and the client, as well as any positive or negative experiences.

it works, no problem at all, in your client's logs you'll see a message like:

---
[60010.976717] Lustre: Lustre: Build Version: 2.10.4
[60011.029258] LNet: Added LNI 10.64.102.152@tcp [8/256/0/180]
[60011.029297] LNet: Accept secure, port 988
[60011.042970] Lustre: Server MGS version (2.5.5.0) is much older than client. Consider upgrading server (2.10.4)
