Hi, all 2015-03-16 15:55:11.124711 7fa0629da700 0 bad crc in data 2453778563 != exp 2391663503 why we always got those error, probably consecutive several pieces for every three or four days? As is known for us, TCP layer uses its own crc verification to guarantee the correctness of the receiving data in network. So we may assume the main reasons coming from the memory error with non-ECC main memory? If so, we also cannot guarantee the data we write to the physical storage is correct with non-ECC memory? Then it may cause the data-inconsistency (and we may repair it during scrubing repair process if the content is owned by object data, or it may lead to osd error, if the inconsistent data occurs in pg_log, pg_info or osdmap?)
