Hi,
I would like to know if it's possible to install Lustre client on an 32bit
version Linux, especially CentOS/RedHat.
Thank you,
Dennis.

It should be possible in theory, but we haven't been testing this for the past few
releases (maybe 2.5 and later) due to non-existent user demand for 32-bit clients.
Several bugs for 32-bit clients were fixed the last year, and I _think_ the current master
branch compiles on 32-bit CPUs.
I'm open to landing patches to fix such issues if you find them. You might be better
off just spending $60 for a 64-bit CPU :-).
Note also that there is a 16TB file size limit for 32-bit kernels.
Cheers, Andreas

I don't know about the 2.x branches, but not long ago, jenkins kindly
informed me that I broke i686 builds in a patch I submitted for
lustre-master patch. So I can confirm that they are building and tested
for el6 with lustre-master ;-) The real target is Intel's MIC platform,
but the automated build and testing appears identical to the x86_64
platforms. It may not get any additional testing or real hardware
testing, but there is still some usage, and I would expect it to mostly
work.

More like $25... Unless this is a specialized processor like MIC, I
have to agree.

Nope, it's an old plain 32Bit processor.
You know how it goes, if it's working don't break it ;) not my philosophy
though :)
Thanks for the info and the tips :)
