Abstract: End-to-end checksum is an effective means of data integrity detection, which can provide basic reliability guarantee for the distributed storage systems. Glusterfs is a popular stacked distributed file system, but it lacks an effective data integrity detection mechanism. User data storage in the Glusterfs have a risk of being damaged and not being discovered. Moreover, this kind of risk can spread in some cases, causing data loss even with the protection of multiple copies or disaster recovery. This paper proposes a cost-effective Glusterfsbased end-to-end checksum scheme called Glusterfs-E2E, which can effectively solve the data integrity risk of Glusterfs. The proposed solution can not only provide full path protection, 2% to 8% performance overhead, but also can locate software bugs.
