<div dir="ltr">Hi Jim,<div><br></div><div>The common non-GPFS-specific way is to use a tool that dumps all of your filesystem metadata into an SQL database and then you can have a webapp that makes nice graphs/reports from the SQL database, or do your own queries.</div><div><br></div><div>The Free Software example is "Robinhood" (use the POSIX scanner, not the lustre-specific one) and one proprietary example is Starfish.</div><div><br></div><div>In both cases, you need a pretty beefy machine for the DB and the scanning of your filesystem may take a long time, depending on your filesystem performance. And then without any filesystem-specific hooks like a transaction log, you'll need to rescan the entire filesystem to update your db.</div><div><br></div><div>Regards,</div><div>Alex</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Fri, Apr 3, 2020 at 3:25 PM Jim Kavitsky <<a href="mailto:jkavitsky@23andme.com">jkavitsky@23andme.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr">Hello everyone,<div>I'm managing a low-multi-petabyte Scale filesystem with hundreds of millions of inodes, and I'm looking for the best way to locate archivable directories.
