Hardware malfunctions must be avoided as much as possible, and any software that is required for operation must also be able to continue running uninterrupted even while new components are being added to it. Selection Phase 2 Objective: select the best cluster filesystem for the specific load (GFS2 vs OCFS2) Created a custom set of scripts to simulate researchers' load: creation of about 10.000 directory trees, 8 levels with 3 subdiretory each (tree_gen.sh) creation of one file for each leaf directory of 1600 bytes (crea_grf.sh) So, I embarked on a mission to combine my various network storage boxes into one big SAMBA share using GlusterFS. General Concepts Libvirt provides storage management on the physical host through storage pools and volumes. This is why I suggested setting static IP addresses during the OS install.
