short update on where we are headed
by Steven Dake 18 May '10

18 May '10

Hi, Posting a short update as to where we are headed. I have had a good long look at the sheepdog source base and believe the sheepdog devs and community have developed a great solution. To say it is brilliant is an understatement. Since there is no point in re-inventing the wheel when a better one already exists, I want us to solve one obstacle to wide-scale sheepdog deployment. In simple terms, sheepdog requires a membership system and low performance atomic commit framework. Corosync provides a membership system and very high performance atomic commit framework, but at low scale. By relaxing performance requirements around commits, we can scale to very high node counts. The goals of this project are changing as a result to provide a high scale membership protocol (d1ht) as well as low performance commit framework. While I personally feel this has many applications outside of sheepdog, our first target will be to provide a framework for which sheepdog can use for membership and commit. Regards -steve

announcement of the vinzvault project
by Steven Dake 14 May '10

14 May '10

CCing openais and linux-cluster ml since there may be some cluster developers interested in participating in this project there. I am pleased to announce we are starting a new project called vinzvault to help resolve some of the difficulties in deploying virtual machines in data-centers. There are other projects that use similar technology or have similar goals as ours. The Ceph filesystem provides a cloud file-system for large scale machines to use as storage. Hail provides a S3 API for accessing information. Cassandra provides a distributed database using techniques similar to what we are planning to provide eventually consistent replicated bigtable style databases. Our project is focused around one goal: providing a small footprint (10kloc) highly available block storage area for virtual machines optimized for Linux data-centers. Our plans don't depend on SAN hardware, software, hardware fencing devices, or any other hardware then is commonly available on commodity hardware. We intend to trade these lower-scale high cost technologies for higher-scale lower cost techniques. Some of our requirements: * Easy to use, deploy, and manage. * 100,000 host count scalability. * Only depend on commodity hardware systems. * Migration works seamlessly within a datacenter without SAN hardware. * VM block images can be replicated to N where N is configurable per VM image. * VM block images can be replicated to various data centers. * Low latency block storage access for all VMs. * Tuneable block sizes per VM. * Use standard network mechanisms to transmit blocks to the various replicas. * Avoid multicast. * Ensure only authorized host machines may connect to the vinzvault storage areas. * No central metadata server - everything is 100% distributed. We plan to execute this project using an overlay DHT hash table called D1HT(1). The 1 in D1HT indicates there is, in a majority of cases, only 1 network request/response required per block of storage. Like all solutions that trade performance for scale/cost, our project may not meet your deployment needs, but we aim to focus on correctness first and performance second. We hope readers will participate in the development of this LGPL/GPL open source project. Our mailing list is vinzvault(a)fedorahosted.org. One final note - no code is in our repo yet - that is for developers interested in this technology to make happen (this is a from scratch implementation). Lets get cracking! Regards -steve (1) http://www.cos.ufrj.br/~monnerat/D1HT_paper.html

[PATCH] Verify events are from predecessor before resetting tdetect
by Steven Dake 14 May '10

14 May '10

In a 4 node cluster, stopping two nodes at about the same time would result in one node leave event not being detected. This is caused by tdetect being reset in all cases prior to this patch. This patch only resets the tdetect timer when the event is from the predecessor on the ring. Further, if tdetect expires, a node is unable to detect a new failure in the predecessor. This is because tdetect is not reset in the tdetect timer handler. As long as there is more then one member, tdetect is reset when it expires to potentially catch a failure of two or more nodes.
