Howdy,
See the README file for mmfind for extra information (especially differences between mmfind and 'posix find' / 'GNU find').
If the mmfind predicates you desire are not supported, mmfind's invocation of mmapplypolicy will fail. You should therefore learn whether or not your request was successful within a few seconds.
I did much of the testing for mmfind on a VM using a "file NSD", just as Marc described.
Cheers,
Jamie (principal author of mmfind)

Subject: Re: [gpfsug-discuss] mmfind in GPFS/Spectrum Scale 4.1.1
Date: Wed, Aug 19, 2015 9:18 AM
mmfind in 4.1.1 depends on some new functionality added to mmapplypolicy in 4.1.1.
Depending which find predicates you happen to use, the new functions in mmapplypolicy will be invoked (or not.)
If you'd like to try it out - go ahead - it either works or it doesn't.
If it doesn't you can also try using the new mmapplypolicy script and the new tsapolicy binary on the old GPFS system.
BUT of course that's not supported. AFAIK, nothing bad will happen, but it's not supported.
mmfind in 4.1.1 ships as a "sample", so it is not completely supported, but we will take bug reports and constructive criticism seriously,
when you run it on a GPFS cluster that has been completely upgraded to 4.1.1. (Please don't complain that it does not work on a back level
system.)
For testing this kind of functionality, GPFS can be run on a single node or VM. You can emulate an NSD volume by "giving"
mmcrnsd a GB sized file (or larger) instead of a block device. (Also not supported and not very swift but it works.) So there's no need to even "provision" a disk.
