LFCBrowseSE

LFCBrowseSE can list the files and the amount of storage used by users on a particular SE (useful for data migration in case of full SE). It also supports the replication of the files that are stored on the affected SE.

Install & configuration

Download the tool: Source code and binary (x86-64).

The tool requires the presence of liblcgdm.so.1 and liblfc.so.1. If those do not exist on your system, you may have to create symbolic links like shown below:

# cd /opt/lcg/lib64
# ln -s liblcgdm.so liblcgdm.so.1
# ln -s liblfc.so liblfc.so.1

or, if you are not root user, copy those files to a directory of your choice and add that path to your LD_LIBRARY_PATH variable:

# cp /opt/lcg/lib64/liblcgdm.so /home/myhome/libs/liblcgdm.so.1
# cp /opt/lcg/lib64/liblfc.so /home/myhome/libs/liblfc.so.1
# export LD_LIBRARY_PATH=/home/myhome/libs:$LD_LIBRARY_PATH

Make sure your LFC variables are set, like:

export LFC_HOST=lfc-biomed.in2p3.fr
export LFC_HOME=/grid/biomed/mylogin
