Yes, that was my first impression, too, after reading of how it works. How safe is bcache on that matter? > Anyway, here's a shameless plug for a tool that converts to bcache > in-place: https://github.com/g2p/blocks#bcache-conversion Did I say: I love your shameless plugs? ;-) I've read the docs for this tool with interest. Still I do not feel very comfortable with converting my storage for some unknown outcome. Sure, I can take backups (and by any means: I will). But it takes time: backup, try, restore, try again, maybe restore... I don't want to find out that it was all useless because it's just not ready to boot a multi-device btrfs through dracut. So you see, the point is: Will that work? I didn't see any docs answering my questions. Of course, if it would work I'd happily contribute documentation to your project.
