There's also some cases where you don't care about the devices that develop errors. Wear-leveling delays wear errors until the end of the device's life. Once these start to develop…

I'm not sure I'm following this snap operation. What is a "log tail" in this context? Does this the snap operation still work if we are copying over entries of the log lazily and w…

Reading through 2.3.5 (Lists and Garbage Collection), it looks like it's describing a tree where the leaf nodes also contain references to the root of the next tree. This wouldn't …
