Thanks, I was just about to post that, and I guess is still the reason a dependent fileset is still the default without the –inode-space new option fileset creation.
I do wonder why there is a limit of 1000, whether it’s just IBM not envisaging any customer needing more than that? We’ve only got 414 at the moment but that will grow to over 500 this year.

Maximum number of filesets Version of GPFS Maximum Number of Dependent Filesets Maximum Number of Independent Filesets IBM Spectrum Scale V4 10,000 1,000 GPFS V3.5 10,000 1,000 Another is that each independent fileset must be sized (and resized) for the number of inodes it is expected to contain. If that runs out (due to growth or a runaway user job), new files cannot be created until the inode limit is bumped up. This is true of the root namespace as well, but there’s only one number to watch per filesystem. — ddj Dave Johnson Brown University
