After days of exhaustive debugging, we found the problem to be in the LFC-related environment variables (LCG_CATALOG_TYPE, LFC_HOST, LFC_HOME). According to the CSH test of the SFTs, those vars were supposed to be always correctly set and thus was confirmed after studying the SFTs sources (a mixture of perl and shell scripts). However, we don't know why neither under which circumstamces, sometimes it happens that those vars are not properly set, and consequently the commands fail. The recipe we aplied to solve the problem is quite straightforward; create in all WNs a script under /etc/profile.d/ which sets those vars for users mapped to the dteamsgm account (the one used for the execution of official SFTs): </verbatim> Vincenzo has created a script called it sft.sh and placed it under /etc/profile.d/ on every WN: <verbatim> #!/bin/bash if [ `whoami` = "dteamsgm" ] then export LCG_CATALOG_TYPE=lfc export LFC_HOST=lfc-dteam.cern.ch export LFC_HOME=/grid/dteam/SFT fi </verbatim> This fixes the problem and now the datamgmt tests light up green. -- Main.PeterKunszt - 03 Apr 2006
