What ist he reason about a "spare server" ? With gluster just replicate to the real status all the time!? Or just do geo replication to a non gluster machine!? ----------------------------------------------- EDV Daniel M?ller Leitung EDV Tropenklinik Paul-Lechler-Krankenhaus Paul-Lechler-Str. 24 72076 T?bingen Tel.: 07071/206-463, Fax: 07071/206-499 eMail: mueller at tropenklinik.de Internet: www.tropenklinik.de ----------------------------------------------- -----Urspr?ngliche Nachricht----- Von: gluster-users-bounces at gluster.org [mailto:gluster-users-bounces at gluster.org] Im Auftrag von Ted Miller Gesendet: Freitag, 16. August 2013 18:29 An: gluster-users at gluster.org Betreff: standby-server I am looking at glusterfs for a HA application w/o local tech support (don't ask, third-world country, techs are hard to find). My current plan is to do a replica-4 + hot spare server. Of the four in-use bricks, two will be on "servers" and the other two will be on a "client" machine and a "hot-backup" client machine. No striping, all content on each local machine, each machine using its own disk for all reading. Part of my plan is to have a cold-spare server in the rack, not powered on. (This server will also be a cold spare for another server). I am wondering if this would be a viable way to set up this configuration: Set up glusterfs as replica-5. 1. server1 2. server2 3. client 4. client-standby 5. server-spare Initialize and set up glusterfs with all 5 bricks in the system (no file content). Install system at client site, and test with all 5 bricks in system. Shut down spare server. Once a month, power up spare server, run full heal, shut down. Power up server-spare for any software updates. If server1 or server2 dies (or needs maintenance), tell them to power up server-spare, and let it heal. It seems to me that this would be easier than setting up a replica-4 system and then jumping through all the hoops to replace a server from scratch. Comments, reactions, pot-shots welcome.
