Look at my example, again, closely. I chose the blocksize as 16M and subblock size as 4K and the inodesize as 1K.... Developer works is a good resource, but articles you read there may be incomplete or contain mistakes.
The official IBM Spectrum Scale cmd and admin guide documents, are "trustworthy" but may not be perfect in all respects. "Trust but Verify" and YMMV. ;-) As for why/how to choose "good sizes", that depends what objectives you want to achieve, and "optimal" may depend on what hardware you are running. Run your own trials and/or ask performance experts. There are usually "tradeoffs" and OTOH when you get down to it, some choices may not be all-that-important in actual deployment and usage. That's why we have defaults values - try those first and leave the details and tweaking aside until you have good reason ;-)
