Have any other LND authors (either at Sun or elsewhere) noticed recent
Lustre versions passing iovs with non-page-aligned middle elements down
to the LND layer? We've always seen plenty of misaligned start/end
elements, but prior to 1.6.3 we never saw it with middle elements. We
were advised

Actually they demonstrate setting up a separate MDT to use an existing
MGS. There's even a note that says "specify --mdt

I just checked, and the current Lustre operations manual (v1.14, updated
September 19) does not seem to reflect that belie

In our lab, we have several 108-node and 972-node systems, and we're
using a small (four-node Opteron 2.6.16-27-0.9_lustre-1.6.0.1smp) Lustre
server setup to provide some shared space for applications and such.
Because there are so many client subnets involved and we don't want the
server rout
We're running Lustre 1.6.3 and Linux 2.6.18 on our 972-node
(5832-processor) machines, and we're seeing some interesting problems
when we run executables from a Lustre filesystem. When we run
5000-processor jobs, we often see some - maybe only a few, maybe a
couple of dozen - fail with illegal
