He *removed* sdb and sdc when the failure occurred so sdc would indeed be non-fresh. The key question I think is: will md continue to grow an array even if it enters degraded mode during the grow? ie grow from a 6 drive array to a 7-of-8 degraded array? Technically I guess it should be able to. In which case should he be able to re-add /dev/sdc and allow md to retry the grow? (possibly losing some data due to the sdc staleness) David - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
