BitRot Detection in GlusterFS - Gaurav Garg, Red Hat & Venky Shankar, Red Hat

Do you have lots of "old" data? Does your company archive huge volume of data? If yes, one needs to know this: ageing data is highly susceptible to a mischievous type of tampering popularly know as "Bitrot" or "Data Rot". Data living on storage media are prone to such "insidious" errors due to drive firmware bugs, mechanical wear & tear of rotational media and the likes. Worst, an application relying on such data is practically clueless about it's tampering as there is absolutely no indication from the disk to the storage software layer about such errors. Even data protection mechanisms such as RAID give it a blind eye unless expensive and time consuming approaches are employed.

In this session Gaurav Garg explains how GlusterFS solves this problem by providing an easy and efficient mechanism to detect (and correct) bitrot. This is followed by a quick demo of the implementation.

Gaurav Garg

Software Engineer, Red Hat
I work as a GlusterFS developer at Red Hat involved mostly on the cluster management part of the filesystem. I've been involved in contributing to "BitRot detection in GlusterFS" which is a major upcoming feature alongside other "Data Compliance" mechanisms (such as dedupe, etc..). My past experience involves working on embedded system for motion detection sensors and device drivers. I've passion for open source software development and find... Read More →

Venky Shankar

Developer, Red Hat
I work as a GlusterFS developer at Red Hat involved mostly in the replication subsystem. I am the lead developer of GlusterFS Geo-replication (asynchronous replication) which was one of the initial features that used journals (log) to synchronize data over high latency links (typically over a WAN), followed by log based synchronous replication module. Both of the above replication strategies were presented (by myself and other developers) in... Read More →
