Re: [Pacemaker] HA FTP Server in aws vpc
Have you thought about using a load balancer instead of a VIP? The ELB can span subnets. -- Art Z. -Original Message- From: "Yossi Nachum" Sent: Monday, December 17, 2012 2:22am To: pacemaker@oss.clusterlabs.org Subject: [Pacemaker] HA FTP Server in aws vpc Hi, I want to run ftp server in active passive mode in amazon aws environment. I use a vpc and two subnets: ftp-1 is on 192.168.10.x and ftp-2 is on 192.168.20.x The two subnets are in different availability zones. In this configuration I don't see how can I use a vip so I thought of creating an init script that change the DNS record when one server become the active server. what do you think? does anyone have more elgant solution for this?

[Pacemaker] Locating a clone on 2 nodes of a 4 node cluster
Hello, I need some help with the syntax for making a clone run on two nodes of a four node cluster. I have two OCFS2 filesystems: * cl_fs_share_db should run on nodes aztestc3 and aztestc4 * cl_fs_share_plesk should run on nodes aztestc1 and aztestc2 The files /etc/drbd.d/sharedb.res and /etc/drbd.d/shareplesk.res each specify the correct pair of nodes. How do I update the following pacemaker configuration? Each clone should run in dual-primary mode on both of its nodes. Side question: I have configured just one o2cb. Do I need two of them?

[Pacemaker] One Cluster or Two
Folks, I am building a high availability web hosting platform which will include a pair of web servers with an OCFS2 shared filesystem and a MySQL database server with a backup (using a DRBD-based filesystem instead of MySQL replication). Does this sound like one cluster or two (one for the web servers and a second for the database servers)? If one cluster, each configuration is very very simple. If two clusters, the config is more complex because it has everything in it for all resources, plus location constraints. But it can have a real quorum since the full cluster will be at least four nodes. Thoughts?
