CFS has never tested on this architecture, and I''m not aware of any
other
customer tests there. That said, Lustre isn''t deeply rooted in CPU
architecture specifics so in theory it would work out of the box. We
already handle cross-endian messages between clients & servers.
The only potential problem I forsee is if you have mixed 32-bit and 64-bit
user & kernel-space you might have problems with the ioctl handlers. Your
best bet would be with a Lustre 1.6 beta which doesn''t need them as
much
as 1.4 does.
Please report back any findings.
Cheers, Andreas
