Hi Loic,

1/ -A $USER option is required only when 'who am i' cannot return

   the user's username.  Grid 5000 is such a special environment.

2/ I just updated config-gfarm and config-gfsd to meet your

   requirement.  Now, config-gfsd updates local_user_map of

   gfsd.conf in a private mode.  Does it satisfy your

   requirement?

Thanks,

Osamu

Ok, the Gfarm plugin for ADAGE now uses the "-S" option. From the  

user point of view it makes no difference, but for this plugin this  

is a good step towards "human-readable" code :-)

We still have problem #2: we update the gfsd.conf "local_user_map"  

field with the proper absolute link on each gfsd node.

Thanks,

Loic

Hi all,

we are currently using the svn trunk version of Gfarm v2 as a non  

privileged user (private Gfarm). The "-S" option removes some  

configuration steps to ease the deployment. We are working on the  

Gfarm plugin for the ADAGE deployment tool to take advantage of  

this option (http://adage.gforge.inria.fr/doku.php? 

id=plugin:gfarm). We have some feedbacks :-)

1/ The "-A $USER" option seems to be needed to make config-gfarm  

work. Apparently the "admin_user" field is not filled in case not  

using it (we already had this issue before using "-S"):

==============

local_user_map /tmp/lcudennec/test//etc/usermap

==============

2/ the "local_user_map" field is an absolute link. Is it possible  

to use a relative link as we cannot predict, on the metadata server  

side, where this file will be stored on the gfsd node? (We do not  

assume to have a shared NFS)

Thanks,

Loic
