Hi Marc,

Unfortunately, I find the first paragraph of your response … confusing.  :-O

I understand your 1st sentence … but isn’t one of the benefits of having only 
metadata disks in the system pool the ability to then have separate block sizes 
for your metadata and your data?  If so, isn’t the simplest way to do that to 
have metadataOnly and dataOnly disks?  I recognize that they may not be the 
*only* way to accomplish that…

The concept of "metadata" disks pre-dates the addition of POOLs.  Correct use 
of policy SET POOL rules and assignment of disks or SSDs to pools makes
metadata only disks a redundant, potentially confusing concept that the new 
comer to GPFS (ahem... Spectrum Scale FS) can ignore.

Metadata always goes to system pool.  Other file data can be directed or 
MIGRATed to any pool you like, using SET POOL or MIGRATE rules.
