摘要：Harboring bug may leads system crashes, file system bugs hence corrupt file systems and cause data loss, regardless of the existence of journals and similar defensive techniques. While consistency checkers such as fsck can detect this corruption and restore a damaged image to a usable state, they are generally created as an afterthought, to be run only at rare intervals. But issue is that the fsck is the utility for checking errors in Ext3 file system. In our opinion file system must has its own checker for silent killer known as harboring bug. So Sext3 has this ability and does not need third party checking utility for harboring bug. These modifications in system file allow Sext3 to check system in real time scenario. If we use third party utility the system needs to invoke that utility every time when system is writing data to any field. But in our modification of Ext3 there is no need to invoke the application because the checker is the part of file system. In our proposed solution high memory consumption is only drawback. In addition, we demonstrate the Sext3 performance and competitively with Ext3.
