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.

Hello, I'm beginning to give up on making Linux-HA's heartbeat work for my environment (CentOS x86_64) and am wondering what other option have I got to help me: 1. Use IPVS to maintain a cluster of virtual servers, either master/slave or load-balanced. 2. Use DRBD in master/slave fashion to keep a home-grown application highly-available. The first thing I stumbled upon is RedHat Cluster

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.

What should I use to configure a failover cluster under CentOS? Is there Red Hat Cluster Suite or something like that? Thank you in advance. -- Giuseppe Fuggiano

Hi all, I want to start experimenting with clusters, and I would like to use normal desktop grade hardware for this. I have some extra PC components lying around, enough to build 3 - 4 moderate desktops with a PIV / C2D CPU & 512MB - 1GB RAM each. All the machines should have at least a 100MB NIC, but I can add a gigabit NIC to the machines that doesn't have it if need be. I have used

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

I have a quad core server in which I want to run 4 virtual servers. On this server I have a 1/2 terabyte raid 1 I have split between the 4 members that have the OS on it. I have raid 5 10 terabyte internal storage running on a 3ware 9690a card. I want to share this storage between the servers without partitioning it. Is this possible? -------------- next part -------------- An HTML attachment

Does anyone here on this list have experience with HA clustering? I'm previewing drbd as a potential tool, and wanted to know if anyone here has experiemented with it at all... How stable is it? Does the additional likelyhood of failure given the additional complexity actually get compensated by a better overall system? http://www.drbd.org/ Any feedback is welcome... -Ben --

Hello, I'm testing a HA cluster using Heartbeat and DRBD. I've moved /etc/samba /var/log/samba /var/run/samba and /var/cache/samba to the shared DRBD volume. My problem is that I don't know if these are the only files I should move in the shared volume, I can't find a doc listing all the files used by Samba. Are there other files I should move to the shared volume so that the

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, We are using the heartbeat and drbd packages from latest centos (4.3) extras repository. Upon installation of both packages I noticed that if you "chkconfig heartbeat off" that will cause drbd to chkconfig'ed on. And visa versa. After doing some trouble shooting it turns out the "BEGIN INIT INFO" sections appear to be the cause. drbd has: ### BEGIN INIT INFO #

I have an existing in-production LAMP server running Centos 5.1. It uses physical partitions on top of hardware RAID1, having / /home /var and /boot on separate partitions. We have a near-identical system I am thinking of bringing in as a DRBD/Heartbeat companion. One solution may be to use csync2 [http://oss.linbit.com/csync2/] on /etc and /usr/local (the only areas that will differ from

Hi, I'm wondering what the best option to obtain a high availability asterisk server is. I currently use a TE410P (4 x E1) card. I'm thinking of 2 different solutions: - 2 servers configured with Heartbeat + DRBD (drbd mainly for voicemail....) and the E1 span plugged to the 2 servers (with a TE410P in each server). - 2 servers configures with Heartbeat + DRBD with the E1 span hooked

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:

Hello, I am trying to figure out the best way, how to configure a small cluster with xen and High Availability (Heartbeat). I have two servers and a few virtual machines. What I need is to ensure, that images or partitions of the machines will be mirrored between the two nodes (maybe with drbd?). But that is not all - I also need to enlarge the disks (because of growing databases) of virtual

Hello all, At our office a have a server running 3 Xen domains. Mail server, etc. I want to make this setup more redundant. There are a few howtos on the combination of Xen, DRBD, and heartbeat. That is probably the best way. Another option I am looking at is a piece of shared storage, a machine running CentOS with a large software RAID 5 array. What is the best means of sharing the storage?

hi, I was following this wiki http://wiki.centos.org/HowTos/Ha-Drbd for my CentOS 5 installation, but it appears that the kmod-drdb is not for the newest kernel. Would anyone know how long before this is updated? kmod-drbd i686 8.0.6-1.2.6.18_8.1.14.el5 extras kernel i686 2.6.18-8.el5 installed

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.
