No. > I only have videos and tv recordings in this md The problem with SCT/ERC absence is that the 2-3 minutes of retries suspend IO for that long, and for people running interactive applications (usually LAMP-style web applications) that is a bad idea, but in your case you seem to have just a personal archive of entertainment files. For interactive "enterprise" applications the common practice is to reduce the error timeout to 1-2 seconds, so the failing drive drops out of the MD set quickly and can be replaced, minimizing delays. > which can be replaced with significant effort (about 12TB of > movies and tv shows will take some time to copy from my > DVDs/BDs) Backups are very important, and RAID is not an alternative to backups. You can buy and use SMR disk drives as if they were tapes (or with a filesystem like NILFS2) to do that backup, and they are quite cheap. -- 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
