Hi, Both storage and client clusters have to be on 5.0.3.x to get the AFM revalidation performance with afmRefreshAsync. What are the refresh intervals ?, you could also try increasing them. Is this config option set at fileset level or cluster level ?

Enabling this feature has had zero impact on performance of the software though. The storage cluster is running 5.0.3.x, and afmRefreshAsync has been set there, but at the moment the remote-mounting client cluster is still running 5.0.2.x. Would this feature still have any effect in this setup? Regards, Andreas Mattsson ____________________________________________ Andreas Mattsson Systems Engineer MAX IV Laboratory Lund University P.O.
