I have 5.0.4 for the moment (planned to be updated next year) and what I see is:
[root@sf-dss-1 tmp]# locate mmfind /usr/lpp/mmfs/samples/ilm/mmfind /usr/lpp/mmfs/samples/ilm/mmfind.README /usr/lpp/mmfs/samples/ilm/mmfindUtil_processOutputFile.c /usr/lpp/mmfs/samples/ilm/mmfindUtil_processOutputFile.sampleMakefile Is that what you are talking about ?

It provides a find-like wrapper around the execution of policy rules.

I tried on 900k files and a recursive chmod (chmod 0### -R path) takes about 1000s, with about 50% usage of mmfsd daemon. I tried with the perl’s internal function chmod that can operate on an array of files, and it takes about 1/3 of the previous method. Which is already a good result. I’ve seen the possibility to run a policy to execute commands, but I would avoid to execute external commands through mmxargs, 1M of times; would you ? Does anybody have any suggestion to do this operation with minimum disruption on the system ? Thank you, Alvise _______________________________________________ gpfsug-discuss mailing list gpfsug-discuss at spectrumscale.org http://gpfsug.org/mailman/listinfo/gpfsug-discuss
