If you are running on a more recent version of Scale you might want to look at the mmfind command. It provides a find-like wrapper around the execution of policy rules.
I am not sure that will be any faster than a "chmod -R" as it will exec millions of instances of chmod. What you gain on the swings you are going to loose on the roundabouts.
TL;DR is you want to change permissions on millions of files expect it to take a considerable period of time. Even a modern NVMe SSD probably does around 50k IOPS per second, so best case scenario is one million files taking 40 seconds, at one read and one write per file and that is frankly unlikely.
Also get ready to back them up again. JAB. -- Jonathan A. Buzzard Tel: +44141-5483420 HPC System Administrator, ARCHIE-WeSt. University of Strathclyde, John Anderson Building, Glasgow.
