The following test will not migrate the files, but sends them to stdout (eg. the display).

./llmount.sh
cd /mnt/lustre
cp /bin/ls .
 ~/lustre-cleanup/lustre/utils/lfs migrate -o 0 ls

The problem is in llapi_file_open_param(), where rc is set to 1 by llapi_search_ost(), and then never reset.

Patch will follow.

(I can't believe that didn't break any test!)
