Your problem is likely an old superblock; use wipefs before make-bcache. If you do find a filesystem that doesn't put its blkid magic at a fixed offset from the start of the device, we could consider alternatives, like whitelisting them or porting to blkid. For now, better safe than sorry. -- 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
