Hi All, i've installed a Cluster with Rocks 4-1 without any problem. I'de put the BIoBrew roll during the instalation, and all seems going well. But i notice that in the master node, ther is no "/opt/BIoBrew" directory. I thougth that was normal, as no jobs have to run on the master of one cluster. But when i show the nodes, there don't have this directory. And so, the cluster don't have bioBrew instaled. But the BioBrew roll existe and is enables, as i can see with this command: dbreport rolls os 4.1 i386 enabled biobrew 4.1 i386 enabled base 4.1 i386 enabled ganglia 4.1 i386 enabled kernel 4.1 i386 enabled sge 4.1 i386 enabled area51 4.1 i386 enabled hpc 4.1 i386 enabled web-server 4.1 i386 enabled java 4.1 i386 enabled Should i install the bio roll, or do i reinstall all the cluster? I'm afraid, because we would have to reinstall all of the globus package too :-( Thank's for any help! -- -- Jérôme J'avais mis mes souliers devant la cheminée, le père Noël m'a apporté des pieds.
