Hi all,
is there any guide about compatibility of (OpenBSD) FFS filesystem and
disklabel among different hardware platforms? As I understand it, FFS
filesystems on architectures with different byte endianess are not
mutually compatible. What about different word length with same
byte-endianess? Is FFS2 any different in this respect? The FAQ suggests
that that i386 and amd64 are not mutually compatible.
From http://www.openbsd.org/faq/faq12.html#amd64better :
12.3.3 - Is it always better to run OpenBSD/amd64 on processors that
support it?
Not always.
There are a number of reasons one may desire to use OpenBSD/i386 over
OpenBSD/amd64, even on hardware that supports amd64 code:
[...]
* Need for ability to move disks to another machine that isn't amd64
capable
[...]
Do I understand it right that disks (FFS, disklabel?) from OpenBSD/i386
cannot be accessed on OpenBSD/amd64 or vice versa? I want to share
external backup disks among different architectures and do not want to
screw my data. What is the solution then?
Thanks for your help.
Regards,
David
