This work-around to the defect is submitted by Nick Cardo of NERSC. In summary,
before shutdown, you just do a sync if Lustre reports dirty pages in the
cache...
#!/bin/ksh
cd /proc/fs/lustre/osc
for i in `find . -name dirty_cache_pages -print`
do
cnt=`cat $i`
if [ $cnt -ne 0 ]
then
echo "node has $cnt dirty_cache_pages, sync them"
fi
done
