I've run into a problem mounting an OCFS2 filesystem on a DRBD device. I think it's the same one discussed at http://lists.linbit.com/pipermail/drbd-user/2007-April/006681.html When I try to mount the filesystem I get a ocfs2_hb_ctl: I/O error: [root at node-6A ~]# mount -t ocfs2 /dev/drbd2 /cshare ocfs2_hb_ctl: I/O error on channel while starting heartbeat mount.ocfs2: Error when

Hi all ! Is anyone using xen kernel + drbd 8.2.4 ? I don''t know exactly if my problems come from the addition of the two packages, or from drbd 8.2.4, but I encoutered kernel panic 2 times when trying to do first sync of drbd resources :s Cheers, -- Serge Dewailly _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com

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.

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 #

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 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 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, 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.

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

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 --

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"

trying to follow the ha-drbd HOWTO on the centos wiki... I prep two identical systems with centos 5, leaving some disk space unassigned (they only have one scsi drive), create /dev/sda4 partitions on each to use for the repdata... I install the modules, create a /etc/drbd.conf like... [root at svfis-blade03 ~]# more /etc/drbd.conf # # please have a a look at the example configuration file in

Dear Daniel, Klaus I've try that before But because of how samba work on the files. The Advise is No Without CTDB, you will just shoot yourself on the foot...

Hello, This morning I noticed the following output from "yum update": Installing: drbd82 x86_64 8.2.5-1.el5.centos extras 209 k replacing drbd.x86_64 8.0.11-1.el5.centos As far as I'm aware DRBD works fine for me. Is there a way I can find out about the new release and weather I should upgrade? I can't figure out the CentOS issue tracking system

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

Hi all, I am using heartbeat and drbd on CentOS 5 (see http://www.centos.org/modules/newbb/viewtopic.php?topic_id=7816&forum=41 for details).. DRBD and heartbeat are working, and now I want to put GNBD on top on this. However, I installed the latest CentOS-plus kernel (2.6.18-8.1.8.el5.centos.plus) but there doesn't appear to be a kmod-gndb for this kernel. Looks like the latest

Hiya, I'm new to Centos but learning rapidly but I have been using FreeBSD. I'm trying to setup a HA NFS server using 2 machines. Both machines are running 4.3 updated to the latest via Yum. I did yum groupinstall drbd-heartbeat and yum install kernel-module-drbd-kernel-module-drbd-2.6.9-34.EL to match my kernel. The problem I have is that on 1 machine drbd works fine, but when I start

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.
