One of our HFS datasets is now pushing 40
extents. I was wondering how many this can go
up to.
It depends.
Short answer is 123 extents per volume. 255 extents per multi-vol dataset.
Usually HFS datasets are single-vol, but you can create multi-vol as
well. Multi-vol HFS have to be SMS-managed, while single-vol needn't.
ZFS datasets can be used instead of HFS. ZFSes are VSAM LDS clusters,
typical VSAM limits apply (123 per volume, 255 per multi-vol).
