Hi to all I always used hardwre raid but with my next server I would like to use mdadm. Some questions: 1) all raid controllers have proactive monitoring features, like patrol read, consistency check and (more or less) some SMART integration. Any counterpart in mdadm? 2) thanks to this features, raid controller are usually able to detect disk issues before they cause data-loss. what about mdadm ? How and when do you replace disks ? Based on which params? Do you always wait for a total failure before replacing the disk? Is mdadm able to notify some possible bad-things before they happens ? Many times in the past our raid controllers forced a bad sector reallocation during proactive tasks like patrol read. This saved me many times before. I've tried to not replace a disks when this reallocation was made (it was a test server) and after some weeks the disk failed totally. -- 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
