But today I rebooted the server (for a completely unrelated reason) and when it came back up, the failed array started working just fine, automatically. No error like the above. The array passed fsck with a clean bill of health, but now I'm checking for silent corruption by comparing against backups (except files that have a newer mod time). I would still be interested in knowing what I *should* have done when encountering that error, and if there was any other solution aside from rebooting. If not, I have to say I'm disappointed that a reboot is required to fix this type of issue, because I thought that was a Windows thing, not something to expect from Linux and/or mdadm. One cooincidence that struck me as very funny was that this morning I read the following comic: http://thedoghousediaries.com/4822 But I still didn't think that rebooting would help my raid issue, so I didn't bother to reboot. Later on when I rebooted for a different reason, I realized just how timely that comic was. Special thanks to one "frostschutz" in the freenode #linux-raid IRC channel, who helped me out with all this. -- Daniel Browning Kavod Technologies -- 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
