I don't mind changing the on-disk format, BTW, because I am still able to reformat the disks before the servers go into production. >Support for multiple cache devices is in bcache-dev, it requires changes >to both make-bcache and the kernel.

I have been rolling my own kernels since 1992. I presume that eventually all changes will be upstreamed (including the changes in the on-disk format)? So, until then, I'll simply rebase bcache-dev on top of the most recent kernels manually. I *would* be interested in the new bcache userspace tools though then. -- Stephen. -- To unsubscribe from this list: send the line "unsubscribe linux-bcache" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
