<p class="MsoNormal">How am I just learning about this right now, thank you! Makes so much more sense now the odd behaviors I've seen over the years on GPFS vs POSIX chmod/ACL. Will definitely go review those settings on my filesets now, wonder if the default
has evolved from 3.x -> 4.x -> 5.x.<o:p></o:p></p>

<p class="MsoNormal">IBM needs to find a way to pre-compile mmfind and make it supported, it really is essential and so beneficial, and so hard to get done in a production regulated environment. Though a bigger warning that the compress option is an action
not a criteria! <o:p></o:p></p>
