Hi, Since btrfs is someday going to be the default FS for Linux, and will be on so many single disk PCs and laptops, I was thinking it should be a good idea to insert some redundancy in single disk deployments. Of course it can help with disk failures, since it's obviously a "single" disk, but it can help with bit-rot, and with hardware sector read errors. To get that we'd need to implement some kind of forward error correction, possibly reed solomon code. I am not sure why no filesystem seems to implement such scheme, although I believe at the hardware level, such schemes are being used (so the idea is applicable) ? Not that I am an expert on such matters, but I thought I'd drop that suggestion here, maybe at least I'll know why no one else seems to do that Regards -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
