As part of the output from --explain (on a raid1 with a 1.0 metadata), I see this: Array Slot : 3 (failed, failed, 0, 1) Array State : uU 2 failed I read the first line as "This device is using slot 3. slot 0 is failed, slot 1 is failed, slot 2 is RaidDevice 0, slot 3 is RaidDevice 1" where RaidDevice is the same as in the output for --detail. Is that correct? The second line is more opaque. What to little-u and big-u mean? Does "2 failed" mean the raid thinks two devices have failed? -- Jon -- 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
