[Lustre-discuss] Issue with 1.8.1 patchless client and 1.6.7.2 server

[Scott Barber]

Specs:
All OSSes and MDSs are 1.6.7.2 (Centos 5.2) 2.6.18-92.1.26.el5_lustre.1.6.7.2smp
Client is Ubuntu Jaunty running vanilla kernel 2.6.27.34 and patchless
lustre 1.8.1

Issue:
The client mounts the filesystem just fine without errors. When I try
to copy a file from lustre to a local partition on the client I get a
whole slew of errors:
See http://pastie.org/622029.txt

The only message I see on the MDS and OSSes are:
LustreError: 6028:0:(socklnd_cb.c:2228:ksocknal_recv_hello()) Unknown
protocol version (2.x expected) from 10.2.1.176
but that's expected since the 1.8.1 client tries to use the new
protocol, but then drops back down to the old one.

I'm not sure if it's related to Bug 19561
Is there any other data that I can provide to help figure out what's going on?

Thanks,
