Moving a disk from SPARC to x86

Subject: SUMMARY: Moving a disk from SPARC to x86

Thanks to: Rich Teer, Carsten B. Knudsen, Bernd Schemmer, Tim Chipman,
Darren Dunham, Jason LeDuc, vincent@cojot.name.

There is no practical way to move the disk with the data intact.

Rich and Bernd summed it up most succinctly:

Rich: "You'll have to do a dump and restore, because the on-disk UFS format
is not compatibile between SPARC (big endian) and x86 (little endian).
The disk itself should be OK, but you won't see the data."

Bernd: "IMHO that is not possible due to the different architectures of x86
and
SPARC (little-endian versus big-endian) You must backup the data,
repartition the disk and restore the data."

Dunham points out that: "The anticipated release of ZFS should change this
in the future (will be cross-architecture compatible), but doesn't help you
today."

Thanks to all for your help.
