I just wana ask several questions about NVRAM:
1.We all Know NVRAM will log the write IO,But I wonder if the log including the original Data?If NVRAM has to cache the original data,I think It's too small for the data stream incoming.
2.If the original data is cached in the RAM or NVRAM,does it mirror to the partner node?If not,when the partner node takeover the local node,then the original data cached in the RAM will lost?because the partner node can not get the original data(not log) by each other.
Hope someone can give me the answer...
