Increase fileset limit

The current limits on number of filesets for a Storage Scale file system are:

  • Maximum number of independent filesets per file system: 3000
  • Maximum number of AFM filesets per file system: 1500
  • Maximum number of filesets (dependent + independent) per file system: 10 000

This limitation forces us to create multiple file systems as soon as the client needs directory quota, and no quota based on gid or uid. To meet the customers current sepcifications, we are forced to create 3 file systems to fulfill the requirement of 25.000 directories with directory quota. The site will grow to approximately 50.000 directories within the next 18 months. Splitting the storage system in smaller pieces means a loss of flexibility and very careful planning, as also tiering is involved.

Increasing  the fileset limit to at least  20.000 filesets per file system (with a focus on dependent filesets) would significantly simplify administration and align the product with modern, large‑scale use cases.

We previously requested this enhancement (GPFS-I-755) several years ago, progress since then has been limited.
