The example information I've been able to find isn't clear on proper implementation with multiple backing devices. The following is an exerpt from the documentation. I have 12 backing devices (bcache0 - bcache11).. do I run this just once against any one of the 12, one of the 12 in particular, or do I run this 12 times, once for each of the 12 backing devices that I want cached? ATTACHING: After your cache device and backing device are registered, the backing device must be attached to your cache set to enable caching. Attaching a backing device to a cache set is done thusly, with the UUID of the cache set in /sys/fs/bcache: echo <UUID> > /sys/block/bcache0/bcache/attach Regards, Donald -- 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
