On Amazon EC2, SSD devices on instances are wiped when a machine crashes and between stop/start cycles. Therefore, I'm using them with writethrough bcache in front of slower EBS storage to ensure that my data survives such scenarios, while still benefiting from (some of) the speed they provide. My actual data set isn't expected to grow beyond the size that the cache device offers any time soon, if ever, and so in my case, the optimum behavior of bcache would be to not just cache random data, but contiguous as well. I realize that this isn't how bcache behaves, but I'm wondering if there's any way to tell it to do so? Thanks in advance, Daniel :) -- 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
