Mainlin e in the Linux kernel since 2.6.33\, it is used to replicate data at the block level over the network in a "\;network RAID1"\; fashion. It is generally deployed as a cost effective\, shared-nothing alternat ive to a SAN and used as the building block for high availability cluste rs. Pacemaker is currently the de facto open-source cluster resource man ager (CRM) for Linux HA clustering. With it\, nodes and services can b e monitored and managed to ensure maximum uptime in the face of the most severe service and hardware level failures. Combining the two allows a dmins to %99.999 uptime at a fraction of the price of proprietary altern atives. \;\n \;\nIn LINBIT's second PLUG Advance Topics installmen t\, Adam Gandelman will give a more in-depth view of DRBD and Pacemaker and demonstrate how they work closely together to keep applications runn ing and consistent. During the second half of the presentation\, Adam w ill provide attendees with a real-world example by configuring a highly- available LAMP cluster from the ground up. Though geared toward web serv ices\, the concepts presented can easily be expanded to provide the HA g aurantee to virtually any Linux service. \;\n \;\nAgenda: - Brief re-introduction to DRBD\, Pacemaker and HA clustering concepts. - Overvi ew of various use cases and interesting deployments - Configuration and implementation of a highly-available LAMP cluster using DRBD for data re dundancy and Pacemaker for resource management. \;\n \;\nAdam Gand elman is an expert in open-source clustering and high availability. Orig inally from New England\, Adam lives in Portland\, OR where he has been working at LINBIT\, developers of DRBD and maintainers of Heartbeat. Asi de from providing top-level Linux High-Availability and Disaster Recover y consulting for customers in the Americas\, he leads LINBIT training co urses in the US\, doubles as a technical writer and regularly contribute s to related open-source projects. \;\n\n\nTags: linux\, bsd\, unix\, open source\, plug\, cluster\, ha\n\nImported from: http://calagator.or g/events/1250458641 URL:http://www.linbit.com/en/ SUMMARY:PLUG Advanced Topics: DRBD & Pacemaker part II by Adam Gandelman LOCATION:Roots Organic Brewing [Out of business. *Sigh*]: 1520 SE 7th\, P ortland OR 97214 US SEQUENCE:2 END:VEVENT BEGIN:VEVENT CREATED;VALUE=DATE-TIME:20140909T154537Z DTEND;TZID=America/Los_Angeles;VALUE=DATE-TIME:20140923T200000 DTSTART;TZID=America/Los_Angeles;VALUE=DATE-TIME:20140923T180000 DTSTAMP;VALUE=DATE-TIME:20140909T154537Z LAST-MODIFIED;VALUE=DATE-TIME:20140909T154537Z UID:http://calagator.org/events/1250466959 DESCRIPTION:Join us for the first meeting of the school year as the North west Education Cluster meets for a networking event held in conjunction with the Portland EdTech Meetup group for informal discussions on topics of common interests in education. Featured this month are presentations from Switchboard and Cel.ly\, recent ventures that got their start here in Portland.Clarity Innovations is sponsoring this event because we bel ieve in fostering relationships and synergies within the education and t raining industries to make it a driving force of the Northwest economy. Enjoy free pizza and beer as you network and mingle with peers to celeb rate the Back-to-School season!\n\nTags: edtech\, education\, cluster\n\ nImported from: http://calagator.org/events/1250466959 URL:http://www.meetup.com/PDXedTech/events/203002122/ SUMMARY:NW Education Cluster & PDX EdTech Meetup LOCATION:Lucky Labrador Beer Hall: 1945 NW Quimby\, Portland OR 97209 US SEQUENCE:1 END:VEVENT END:VCALENDAR
