I''ve been experimenting with the lustre client on a non-x86 machine.
It
mostly seems to work, which is good :-} But I also see some evidence of network
communication problems, which is bad :-{
Has anyone written an ethereal plugin for lustre socknal? I looked through
the mail archives, and didn''t see evidence of one, but figured I should
ask
before launching into writing one. IWBNI I had something to use to diagnose
this in addition to looking at logs.
TIA....
Hi,
What architecture is this? We run on PPC, i386, ia64 and x86_64
routinely.
To test networking, you might want to start with "lctl ping", see the
Lustre manual.
We have an old version of tcpdump for Lustre, almost certainly out of
date, but probably in a minor way. I''ve uploaded it on
ftp://ftp.lustre.org/pub/lustre/other/.

There is still ftp://ftp.lustre.org/pub/lustre/other/tcpdump-lustre.tgz that could be used as a starting point if you are interested.

Yup, that looks like there''s something there I can use, at least to
mine for
ideas. Thanx.
