Hi Thanks you for yours post. I am reading your link suggestions of the PostgreSQL. It's helped me for more understand.
I wanted to build a cluster master-master server, and I found the PGCluster tools allow for this environment. But more reading of this topic, the server performance could be worse than a single server. I need build a load balancing cluster of the database. And for that I looking for the node master-master server or read/write server. >From what you're writing, I do assume the following: > -you'll be installing PG on two nodes "behind" a LVS load balancer. > yes > -DRBD is used to give all nodes a shared block storage. > -A shared OCFS2 file system will be run on top of the DRBD volumes. > yes, but now I believe, that's not the best choice for master-master replication Changed, now I prefer build a master-hot standby (read/write node-read only node ) server for the load balancing cluster. It's possible send request for both nodes for build load balance? > If you're considering DRBD-replication (which is limited to two servers), > I'd rather recommend to setup a "typical" active/passive HA setup. > With active/passive HA, I don't offer load balancing. I see about DRBD three-node setup. And also I thinking of the NAS shared-disk, but apparently that isn't compatible with the ocfs, neither with gfs. Which is the best choice for the shared data between databases server, and offer load balancing? I listen of the HAProxy, that offer too load balancing. If I use HAProxy is equal to use LVS, and so I must choice between both. In this moment I don't know HAProxy. -- Sayuri Komatsu _______________________________________________ Please read the documentation before posting - it's available at: http://www.linuxvirtualserver.org/ LinuxVirtualServer.org mailing list - [email protected] Send requests to [email protected] or go to http://lists.graemef.net/mailman/listinfo/lvs-users
