As for the OP, the "failures" are spurious. Running the remove and then the add command puts the disks back in as spare disks, not live ones, and then the array just sits there, doing nothing. I tried the trick of doing echo repair > /sys/block/md0/md/sync_action but the array still just sits there saying it is "clean, degraded", with 2 spare and 5 working devices. -- 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
