Hi, guys: I found that when disk errors happened, it is more likely to locate in md super block area. Kernel messages are like this: end_request: I/O error, dev sda, sector 1953525000 md: super_written gets error=-5, uptodate=0 In some cases, I check if disk is really failed using 'dd' command and found that it is OK for read and write on those sectors. I know that md super block information is located in the end of a disk, but is it related with this problem? Is it safer to put md super block in the start area of a disk? -- The simplest is not all best but the best is surely the simplest! -- 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
