Abstract
A director node of a plurality of nodes determines a plurality of data arrays, where the plurality of data arrays have been discovered at boot time. The director node determines global metadata information, based on reading boot sectors of at least one of the plurality of data arrays discovered at boot time. A determination is made from the global metadata information as to how many data arrays had been previously configured. In response to determining that the plurality of data arrays discovered at boot time is not equal in number to the previously configured data arrays, the director node determines that all configured data arrays have not been discovered.
