*********************************************************
* How to migrate from the RLS to the LFC *
*********************************************************
Author : Sophie Lemaitre <Sophie.Lemaitre@cern.ch>
Date : 15/12/2005
Requirements
============
We assume we have a file with the RLS entries to be migrated in the form :
guid pfn RLS-lfn LFC-lfn
Server
======
For performance reasons, run a insecure LFC server.
Use "make install", instead of "make rpm" (it doesn't work with BuildSecurity NO...)
Client
======
Run the following command from a machine with the following RPMs installed :
- LFC-client (insecure) : use "make install"
- perl-Tk
- perl-DBI
- perl-DBD-Oracle / perl-DBD-Mysql
They are available from :
/afs/cern.ch/project/linux/cern/slc304/i386/SL/RPMS/
Run the command
===============
./migrate_RLS_entries --db-vendor Oracle --host LFC --lrc-user
lcg2_cms_lrc --lrc-passwd xxxxxxxxx --path /grid/cms --file
/root/rls-to-lfc.txt --verbose &> migration_cms_2005_12_14.txt &
The script will :
- create the LFC-lfn (with the directories associated)
- get the file size from the ATTR_size field in the database
- migrate the files to the LFC
Problems ?
==========
Contact Sophie.Lemaitre@cern.ch for help.
