It is worth noting that Independent Filesets are a relatively recent addition to Spectrum Scale, compared to Dependant Filesets. They havesolved some of the limitations of the former.
My view would be to always use Independent FIlesets unless there is a particular reason to use Dependant ones.
One comment about inode preallocation. There was a time when inode creation was performance challenged but in my opinion that is no longer the case, unless you have need for file creates to complete at extreme speed. In my experience it is the rare customer that requires extremely fast file
Ah, yes, I forgot about the quota rationale; we use independent filesets
for that as well. We have run into confusion with inodes as one has to be
careful to allocate inodes /and/ adjust a quota to expand a fileset. IIRC
GPFS generates ENOSPC if it actually runs out of inodes, and EDQUOT if it
We also went with independent filesets for both backup (and quota) reasons for
several years now, and have stuck with this across to 5.x. However we still
maintain a minor number of dependent filesets for administrative use. Being
able to mmbackup on many filesets at once can increase your

We are deploying our new ESS and are considering moving to independent
filesets. The snapshot per fileset feature appeals to us.
Has anyone considered independent vs. dependent filesets and what was your
reasoning to go with one as opposed to the other? Or perhaps you opted to
have both on your
