I think ocfs2 works good on le endian, but maybe not on big endian
though i never test it. From the source code, kernel seemed be prepared
for big endian, but for tools, maybe not, i found lot of codes reading
stuff from disk to memory without conversion in fsck.ocfs2. I am not
sure about other tools, so may need do a full check.

Thanks,
Junxiao.
