I didn't say it cannot. ;-)
BTW: it's tricky! For z/OS v1.x the ZFS cluster has to be SMS-managed to
be EA. Last but not least, you cannot simply ALTER existing (non-EF) ZFS
to be EA.

The 4 GB VSAM limit can be overcome with extended addressability. Here is the
definition I used for V2R1 ServerPac, a ZFS that occupied an entire Mod 27. The
key is data class, which is set in SMS for EA.
DEFINE CLUSTER (NAME(hlq.R21WK2.ZFS) -
VOLUMES(R21WKX) SHAREOPTIONS(3) *DATACLAS(EXT)* LINEAR -
*CYLINDERS(28000,100)* )

What I did.
1. Get into ishell from Opt 6
2. Type /usr/local/
3. In my case, I apparently have nothing mounted there, so I see only
Type Perm Changed-PST8PDT ------Size Filename
_ Dir 755 2013-05-24 22:56 8192 .
_ Dir 755 2014-08-01 14:42 8192 ..
4. Enter u (for File System Attributes) next to one of them.
5. In my case, since I have no other file system defined there, I get the
system-specific root OMVS.sysres.ROOT.
If it's root, then you've been using it inadvertently, and changing the size
will be a BFD. If you see a subordinate file system there, then that's the one
you have to increase. I'm not adept at that this part, but you would create a
new bigger one, copy over all contents from the old, unmount the old one, and
mount the new one at the same point. Good luck.
Another method would be "df" command.
From unix prompt issue "df /your/directory"
or "cd /your/directory"
and then "df . "
You'll get filesystem name = ZFS or HFS dataset name.
Then look at dataset parameters. There are many factors which can limit
growth:
- number of extents
- free space on the volume
- multi-volume
- candidate volumes availability
- 4GB limit for VSAM
