You could try DFDSS Dump and restore. In two separate jobs, you can
increase the file allocation on the DFDSS dump and them rename the files on the
DFDSS restore!!

Subject: Re: Can you use IDCAMS REPRO on zFS files
Well, I should have been more specific. I don’t see a way to make it bigger
either, but in this case Lizette said it was already 200 cylinders. DFDSS
copy could create a new one 200 cylinders large, with very few extents, and my
next move would have been to do a ZFSADM grow immediately to get it to the
desired size. I personally try to avoid any of the copytree "stuff" or just a
brute force mv where possible, just due to the essence of time.

Subject: Re: Can you use IDCAMS REPRO on zFS files
I've never had any luck resizing ZFS using the DSS copy, I'd be curious if that
works for Lizzette zfsadm grow will work if the zfs was allocated with a large
enough primary, my personal preference, rather than having many extents to get
my final results, plus John makes a good point The only reason that I can think
of is if the zFS filesystem LDS was originally created with a DataClass which
did not have "extended addressing" and so is limited to 4 GiB.
I still prefer allocating a new linear vsam file large enough and REPRO the old
to the new, and mount that file at /u/userid/tmp and see if it contains all the
data you expect to be there, I've done this with a vendor's ZFS file that was
created incorrectly .

Ok, well in that case, I'd just DFDSS copy it. In fact, if you can unmount it
first you can copy it, and have DSS rename it back to the original name all in
one operation, then just remount it.
//STEP1 EXEC PGM=ADRDSSU,REGION=8M
//SYSPRINT DD SYSOUT=*
//SYSIN DD *
COPY DS(INC(your.zfs)) -
ALLDATA(*) -
SPHERE -
DELETE -
ALLX -
CATALOG -
PURGE

So the file was allocated at 1,1 CYL. It is now at 200Cyls. And 200 extents.
I like to resize the space allocation so it does not have to do
EXTEND - FORMAT
EXTEND - FORMAT
EXTEND - FORMAT
Dozens of times and possibly impacting the performance for the user.
