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
