Experiences building a distributed shared log on RADOS - Noah Watkins

Ceph Community

This document summarizes Noah Watkins' presentation on building a distributed shared log using Ceph. The key points are: 1) Noah discusses how shared logs are challenging to scale due to the need to funnel all writes through a total ordering engine. This bottlenecks performance. 2) CORFU is introduced as a shared log design that decouples I/O from ordering by striping the log across flash devices and using a sequencer to assign positions. 3) Noah then explains how the components of CORFU can be mapped onto Ceph, using RADOS object classes, librados, and striping policies to implement the shared log without requiring custom hardware interfaces. 4) ZLog is presented

Basic and Advanced Analysis of Ceph Volume Backend Driver in Cinder - John Haan

Ceph Community

This document discusses basic and advanced features of using Ceph as the backend driver for Cinder block storage in OpenStack. It begins with basic concepts like Cinder volumes, snapshots, and backups using RBD copy-on-write, snapshots, and export/import diffs. More advanced topics covered include image-cached volumes to improve volume creation performance, and replication between Ceph clusters for disaster recovery using RBD mirroring. The document provides configuration details and diagrams to illustrate how data is stored and managed in Ceph for basic and advanced Cinder integration.

How does Ceph perform when used in high-performance computing? This talk will cover a year of running Ceph on a (small) Cray supercomputer. I will describe how Ceph was configured to perform in an all-NVME configuration, and the process of analysis and optimisation of the configuration. I'll also give details on the efforts underway to adapt Ceph's messaging to run over high performance network fabrics, and how this work could become the next frontier in the battle against storage performance bottlenecks.

Linux Block Cache Practice on Ceph BlueStore - Junxin Zhang

Ceph Community

This document discusses using Linux block caching with Ceph BlueStore. It explains that BlueStore can better utilize fast storage devices like SSDs compared to FileStore. It tested using Bcache and DM-writeboost to cache BlueStore data on HDDs using SSDs. Bcache performed better overall. Issues found were slow requests when caching and BlueStore used the same SSD, and inconsistency in SSD data management between BlueStore and the cache. Future work could have BlueStore control all raw disks and prioritize data saving to fast devices.

Troubleshooting redis

DaeMyung Kang

This document discusses troubleshooting Redis. Some key points: - Redis is single-threaded, so commands like KEYS, FlushAll, and deleting large collections can be slow. It's better to use SCAN instead of KEYS. - Creating Redis database snapshots (RDB files) and rewriting the append-only file (AOF) can cause high disk I/O and CPU usage. It's best to disable automatic rewrites. - Monitoring memory usage and fragmentation is important to avoid performance issues. The maxmemory setting also needs monitoring to prevent out-of-memory errors. - Network and replication failures need solutions like DNS failover or using Zookeeper for coordination to maintain high availability of Redis

Removing Uninteresting Bytes in Software Fuzzing

Aftab Hussain

Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process. In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds. - These are slides of the talk given at IEEE International Conference on Software Testing Verification and Validation Workshop, ICSTW 2022.
