Hi,

I've been running some more tests of the staging at RAL and have run
into a problem somewhere in the mps_Stage/PreStage/prep system.

Everything work fine staging file that was on the system and has been
deleted but if I try to stage in a file that was one a different server,
hence the directory structure for the file does not exist on the staging
server it fails and I see the following error in the PreStage log file:

12:45:43 [ 10859] mps_Stage: Open
'/stage/bdata-data50/kanga//store/SPskims/R12/16.0.2e/BtoKKKL/001005/200
002/DIR_LOCK' r/w failed; No such file or directory.
12:45:43 [ 10859] do_stagein: xfr failed for

12:45:45 [  3255]

.01.root, rc=1024, reqid=ef000001:1cd2.425d27e1
:3762

If I create the directories and the DIR_LOCK file before running the
import, everything works.

The config file I'm using on the server is below.

Is there some setting I'm missing which is needed to create the
directories/DIR_LOCK file or does the code need fixing?

Thanks,
Chris
