[Oesterlin, Robert]

Thanks, - I kicked it off and it finished in about 12 hours, so much quicker than I expected.

Bob, like most questions of this time I think the answer depends on a number of variables.  Generally we do not recommend running the mmcheckquota command during the peak usage of your Spectrum Scale system.  As I think you know the command will increase the IO to the NSDs that hold metadata and the number of NSDs that hold metadata will contribute to the time it takes for the command to complete, i.e. more metadata NSDs should improve the overall execution time.
