Hi Eli,

as I can tell, we are running the Lustre Client 2.10 with a 2.5 version
in the backend without problems since 1 month so far.

If you are running the Robinhood Policy Engine with that setup, you
probably will get the conflict we had here during the changelog
processing phase. We got an error regarding the Lustre changelog API, so
we are running an older Lustre client version on the Robinhood client
that works pretty well.


Best regards
Gabriele
