I tried both of those, and neither of them prints a grand total at the end.

What do you mean? pdu always print a tree structure. The root of this tree should be equal to grand total.

yes, the output is certainly different from what you show.
I don't know much about the pdu from PURE storage, except that the man page says May 2018.
Patrick

Did you install that pdu from a Linux distro? What distro is it? (Just curious)

BTW, my pdu stands for "parallel-disk-usage". And I guess that pdu stands for "PURE's Disk Usage"?

The PURE Storage stuff was already installed on the computer that I am using.

I think the p in pdu might stand for parallelizable. There are a bunch of PURE Storage commands available, like pls, which has the man page title pls - Utility to parallelize an ls call to an NFS server, and for pdu the page title is pdu - Utility to parallelize a du call to an NFS server. Some of the other PURE Storage commands are pchmod, pchown, pfind, and prm. I just found out about the PURE Storage pdu today, and I do like it better than du.

I searched "pdu - Utility to parallelize a du call to an NFS server" on Google and found no relevant result, lol. Anyway, I hope you can find the right issue tracker soon.

I just searched for "pure storage pdu" on Google, and this was one of the hits:
