So you can _perhaps_ predict the next disk with problems. Unfortunately, SMART-data is no credible basis for any hard disk failure predictions. For further information, you may want to take a look at this german link: http://www.heise.de/newsticker/meldung/Google-Studie-zur-Ausfallursache-von-Festplatten-147178.html and / or at this document http://labs.google.com/papers/disk_failures.pdf > > Scary. Yes, the server uses the same model for all 9 devices. Yeah, that's really scary - it shows, that even with a RAID6 your data is not absolutely safe. But I have to admit that this is "only" the worst case scenario - the chance that this situation occurs, is really small (but not impossible). I suppose, that your customer keeps his backups up to date although he uses a RAID6? > From your domain I see that you seem to be located in germany, so you > might know the manufacturer of the server: transtec. > No, I do not know this manucaturer - but I'm just a private user, so I don't really have any experiences with "real" servers :) Best regards, Yann -- 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
