This is my first crack at bcache and I configured a cache device with defaults using make-bcache -C /dev/sda Now I've got better info on my SSD and know what the block and bucket sizes should be, however I can't run the command again with errors that the device is busy. I never did anythign beyond just creating the cache and backing devices. I never registered the cache device, never created a filesystem. -- 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
