It's likely that either the bcache module is not loaded: lsmod |grep -q bcache || modprobe bcache Or you didn't compile the kernel with bcache support. Using: make menuconfig In your bcache source tree, Navigate to "Device drivers" --> "Multiple devices driver support (RAID and LVM)" --> "Block device as cache" and ensure that it is either built-in <*> or as a module <M>. If it is not enabled, you'll need to recompile with one of these options. -davidc -- To unsubscribe from this list: send the line "unsubscribe linux-bcache" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
