Nir, Tal, any idea on why the storage pool is not getting up? I see vdsm is in recovery mode, I'm not sure if this was what the test was supposed to do or if the intention was to cleanly shutdown vdsm and cleanly restart it. -- SANDRO BONAZZOLA MANAGER, SOFTWARE ENGINEERING, EMEA R&D RHV Red Hat EMEA <https://www.redhat.com/> sbonazzo(a)redhat.com <https://red.ht/sig>
