In general, when writing messages to this list, you need to be more
concise about what you are asking. I see so much information here, I'm
not sure what is relevant to your few interspersed questions and what is
not. I will try to answer your specific question...
Also, in the future, please use a simple plain-text format and just copy
and paste for plain-text content. All of the "quoted-printable"
mime-types are confusing my MUA.

You need to look at the mkfs.ext3 manpage on how to create an external
journal (i.e. -O journal_dev external-journal) and attach an external
journal to an ext3 filesystem (i.e. -J device=external-journal) then
apply those mkfs.ext3 options to your Lustre device with mkfs.lustre's
All of this is covered in the operations manual in section 10.3
"Creating an External Journal".
