Hi all, actually, what you would like to do is already possible, albeit it will kill the performance of a rotating, mechanical, HDD. With SSD might work better. If you take an HDD and partition it, let's say with 100 partitions (GPT will be required), then you can build a RAID-6 using this 100 partitions, having a redundancy of 2%. Taking two, or more, of such configured RAID-6, it will be possible to build (with them) a RAID-1 (or else). If a check of this RAID-1 returns mismatches, it will be possible to check the single devices and find out which is not OK. With RAID-6 (per device), and a bit of luck, it will be possible to fix it directly. Of course a lot of variables are tunable here. For example the number of partitions, the chunk size, or even the fact that with X partitions it could be possible to build more than one RAID-6, increasing the effective redundancy. All with the performance price I mentioned at the beginning. bye, -- piergiorgio -- 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
