Hi everyone, I need some help to setup my configuration failover system. My goal is to have a redundance system using Xen + DRBD + Corosync + Pacemaker On Xen I will have one virtual machine. When this computer has network down, I will do a Live migration to the second computer. The first configuration I will need is a crossover cable, won''t I? It is really necessary? Ok, I did it. eth0

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi! I think I stumbled on at least two bugs in the CentOS 7.2 pacemaker package, though I'm not quite sure if or where to report it. I'm using the following package to set up a 2-node active/passive cluster: [root at clnode1 ~]# rpm -q pacemaker pacemaker-1.1.13-10.el7_2.4.x86_64 The installation is up-to-date on both nodes as of the

Hello all, I am trying to create a corosync/pacemaker cluster using CentOS 6.0. However, I'm having a great deal of difficulty doing so. Corosync has a valid configuration file and an authkey has been generated. When I run /etc/init.d/corosync I see that only corosync is started. >From experience working with corosync/pacemaker before, I know that this is not enough to have a functioning

Hi, I've setup two server A + B (debian etch) with drbd + heartbeat in active/passive mode. If the primary server A fails, the shared storage is mounted on B, the virtual ip A-vip moves to the new primary B and samba is started by heartbeat. This works well, but I'm not sure which samba files should be identical on both server. Both have a dedicated machine account at the moment.

Hi guys I'm wondering if anyone here is using the GlusterFS OCF resource agents with Pacemaker on CentOS 7? yum install centos-release-gluster yum install glusterfs-server glusterfs-resource-agents The reason I ask is that there seem to be a few problems with them on 3.10, but these problems are so severe that I'm struggling to believe I'm not just doing something wrong. I created

Hi, Can u please explain for what purpose pacemaker cluster used here?

Hi, We''re setting up fairly large Lustre 2.1.2 filesystems, each with 18 nodes and 159 resources all in one Corosync/Pacemaker cluster as suggested by our vendor. We''re getting mixed messages on how large of a Corosync/Pacemaker cluster will work well between our vendor an others. 1. Are there Lustre Corosync/Pacemaker clusters out there of this size or larger? 2.

Hi, I cannot 'halt' my CentOS 6 servers while running corosync+pacemaker. I believe the runlevels used to stop corosync and pacemaker are not in the correct order and create the infinite "Waiting for corosync services to unload..." loop thing. This is my first time with this cluster technology but apparently pacemaker has to be stopped /before/ corosync. Applying the following

Hi all, could somebody point me to what is considered a sound way to offer Xen guests on a two node DRBD cluster in combination with Pacemaker? I prefer block devices over images for the DomU''s. I understand that for live migration DRBD 8.3 is needed, but I''m not sure as to what kind of resource agents/technologies are advised (LVM,cLVM, ...) and what kind of DRBD config

Hello, While working on heartbeat/pacemaker for a web service stored on drbd, I've thought what I've learnt could also be applied to samba in order to build a fault tolerant file server in our domain. While digging samba's doc, I've found that CTDB could also fulfill the need and is maybe better suited as it's samba-related. But on the other hand, I'd appreciate to begin

Hello, well, the subject says it all :-) Could drbdlinks ( http://www.tummy.com/Community/software/drbdlinks/ ) be added to Extras repo, alongside DRBD packages ? Thanks in advance

Hi, I been working on for about a month and half on setup drbd and nfs. I keep running into issue with the way heartbeat/pacemaker handles nfs. Does anyone know a good way to set up a HA NFS server with DRBD and Heartbeat and NFS. I am willing to share my pain in setting it up.

Hi, I want to combine all the above mentioned technologies. The Linbit pages warn not to use the drbd: VBD with HVM DomUs. This page however: http://publications.jbfavre.org/virtualisation/cluster-xen-corosync-pacemaker-drbd-ocfs2.en (thank you Jean), simply puts two DRBD devices in dual primary mode and starts Xen DomUs while pointing to the DRBD devices with phy: in the DomU config files.

Hi, right now I am using only one external server as a gateway for the internal servers. I would like to enable a fail-over on a second server. To implement the floating VIP, should I use heartbeat+pacemaker? Or is there something more "lightweight"? Basically, I just need server2 up the VIP when server1 is down, and server2 down the VIP when server1 is back up (or server 1 does not up

Hi, I've just created again the gluster with NFS ganesha. Glusterfs version 3.8 When I run the command gluster nfs-ganesha enable - it returns a success.

I asksed about this in November last year but got on response. Anyone have any ideas now? Does anyone here have any experience with using KVM/libvirt with RAID1 over IP/DRBD or other HA solution? I'm trying to figure out the hardware configuration I would need to be able to survive a failure or planned shutdown of any one unit in a virtualization cluster. KVM/libvirt makes moving

Hello all, has someone worked with DRBD (http://www.drbd.org) for HA of mail storage? if so, does it have stability issues? comments and experiences are thanked :) Thanks, Rodolfo.

Hi, I want to upgrade from 8.0 to 8.1 but yum update does not work. Still 8.0 Probably the cause is that I compiled DRBD myself because it was not available for 8.0 when I set up the machine. Now yum update says: Error: ?Problem 1: cannot install the best update candidate for package drbd-pacemaker-9.11.0-1.el8.x86_64 ? - nothing provides pacemaker needed by
