Here's what I do:
Step 1
IDCAMS DEFINE with whatever space and volume allocation is necessary.
Step 2
//CREATE EXEC PGM=IOEAGFMT,REGION=0M,
// PARM=('-aggregate data.set.name.ZFS -compat')
I don't tell ZFS how many blocks to format.
Finally, in SYS1.PARMLIB(IOEPRM00), I specify only one parameter:
aggrgrow=on
This has worked very well for us - at least so far.
