Hello Everyone,

Is it possible to reset the rpc-related statistics (i.e. avg_waittime, read_data_averages, write_data_averages etc.) in osc.*.import without remounting the client?

If yes, what is the command to do so? If not, then if I periodically reset the counters by modifying the Lustre source code, what kind of impact will it have for the client or the file system itself?

Yes, you can clear the client stats like "lctl set_param osc.*.stats=0".

Cheers, Andreas
