We routinely use DSS dump/restore to clone/migrate ZFS around the enterprise, but always to similar architecture. The only humongous (EF) ZFS I've created was for ServerPac work space, and I started with an empty volume. I agree with what's been said about radically different internals in EF. Dump/restore is probably out of the question.

Sent by: IBM Mainframe Discussion List <IBM-MAIN@LISTSERV.UA.EDU> I agree with your curiosity. I have never tried to "clone" a zFS using REPRO, but have copied other VSAM LINEAR data sets (SMS ACDS, SCDS) with no problems. But I didn't change them from non-EF to EF at the same time. Perhaps an EF LINEAR data sets is not identical to a non-EF LINEAR data set in some way. Or perhaps the UNIX formatting thereof is different. Hum, that sounds like a possibility. A non-EF zFS is _known_ to not be >4Gib, and so some internal structures might be unsigned 32 bit whereas in a EF zFS, they need to be 64 bit. Just a SWAG on my part. Perhaps Bill Schoen will put in a good, and definitive, word on this.
