[lustre-discuss] interoperability between lustre client and lustre server version

[Bertini, Denis Dr.]

Hi Peter,

Thanks for the quick answer.

The exact server version we are running is 2.12.5. Do you see an potential issue running such a server version with clients version 2.15.6?

Furthermore, i would like to know how long will the  2.12.x ( latest x=9) lustre server version be updated/supported ?

Do you know?

Cheers,

Denis

You don’t specify which 2.12.x release that you are using but in theory it should be fine to continue to upgrade to newer 2.15.x releases as they are issued – we test interoperability with the latest 2.12.x release as part of the pre-release validation for 2.15.x releases.

Hi,



We have a server version 2.12  which can interoperate without problem with higher lustre client versions ( up to 2.15.6 at the moment ).

My question is how long can we update the client version on our compute nodes  without having problem with the "old" luster server version 2.12?

thanks in advance,
