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 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

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.

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

You could also use pacemaker to manage promoting the drbd device and mounting it with a dead master role as a dependency. Are you using anything to automatically promote the send slave already?

I am running a two-node web cluster on OCFS2 via DRBD Primary/Primary (v8.3.8) and Pacemaker. Everything seems to be working great, except during testing of hard-boot scenarios. Whenever I hard-boot one of the nodes, the other node is successfully fenced and marked ?Outdated? * <resource minor="0" cs="WFConnection" ro1="Primary" ro2="Unknown"

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

I'm trying to setup a pair of FreePBX-4.211.64 boxes using Pacemaker, Corosync, and DRBD. All the examples I've found so far use Heartbeat, but Heartbeat is not in the repositories and doesn't want to compile from source. Does anyone have a working configuration they can share or a tutorial they can point me to? Also, what does drbdlinks bring to the party? Isn't just linking

Hi all, I'm happy to announce a new tutorial! https://alteeve.com/w/2-Node_Red_Hat_KVM_Cluster_Tutorial This tutorial walks a user through the entire process of building a 2-Node cluster for making KVM virtual machines highly available. It uses Red Hat Cluster services v3 and DRBD 8.3.12. It is written such that you can use entirely free or fully Red Hat supported environments.

Hi everybody, our university uses a Samba 3.6.9 server as PDC for a windows domain on a single physical server (external LDAP on another server is used). To get some redundancy up running a second physical machine was bought, which is exactly the same as the one running. Now I?m searching for the best way to get the job done. The first thought was to build a HA-Cluster with Corosync/Pacemaker

Hi guys, I'm looking at the possibility of running a pair of servers with Dovecot LDA/imap/pop3 using internal drives with DRBD and GFS (or other clustered FS) for the mail storage and ext3 for the root drive. I'm currently using maildrop for delivery and Dovecot imap/pop3 with the stores over NFS. I'm looking for better performance but still keeping the HA element I have now with

hey, I have an application for drbd replication between a pair of EL6 servers, and I just realized that drbd is no longer built in. googling found me this blog on doing it using ElRepo distributions... http://www.broexperts.com/2012/06/how-to-install-drbd-on-centos-6-2/ is that still best practice? or is there a better distribution? or really... my application is a BackupPC server

Hi We've got drbd going between 2 nodes:) ATM there is un-partitioned space on each node but (we think) they are syncing OK. It looks as though it has synced the whole partition (2GB) from the primary node 1 to the other node: node 1 smb1:/home/steve # cat /proc/drbd version: 8.4.4 (api:1/proto:86-101) GIT-hash: 3c1f46cb19993f98b22fdf7e18958c21ad75176d build by SuSE Build Service 1:

Hi, Not totally new to Xen but still very green and meeting some problems. Feel free to kick me to the DRBD people if this is not relevent here. I''ll be providing more info upon request but for now I''ll be brief. Debian/Squeeze running 2.6.32-5-xen-amd64 (2.6.32-21) Xen hypervisor 4.0.1~rc6-1 and drbd-8.3.8. One domU configured, with disk and swap image: root =

We have two virtual machines on ESX 3 running CentOS 4.3 and we'd like to turn them into some sort of highly available nfs file server. Currently, I am familiar with DRBD and RHCS but I was curious what others might recommend in such a situation. I'm not sure how easily we could use RHCS in such a situation because we don't really have the advantage of shared storage in this setup.

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

Bonjour, J''aimerai mettre en place un cluster sous Xen ou XenServer avec 2 serveurs dell R 710. J''aimerai pouvoir monter un cluster en utilisant l''espace disque entiere des 2 serveurs cumulés ainsi que la mémoire Quelles sont vos retour d''expériences et vos configurations? Merci d''avance Cordialement Mat
