similar to: CentOS 4.4 lvm and drbd 0.8?

Regardless of the filesystem (i''ve used reiserfs, xfs, ext3), whenever I mount a fresh DRBD partition I get some nasty kernel messages. This is under Debian Sarge, Xen kernel 2.6.11.12-xen0 (dom0) using DRBD v0.7.11 (pulled from Debian "testing"). This is what I did to create the partition. On both nodes I created a new LVM storage device and started DRBD: # lvcreate

Hi all, we have followed the very good HOWTO by http://wherethebitsroam.com/blogs/jeffw/drbd-xcp-05 and set up DRBD on XCP 1.1 in primary/primary mode. It works fine, but I am wondering how to squeeze more performance out of the system (we currently use a crossover GB Ethernet connection). When writing a 1 GB file on a guest I get write performance of about 5MB/s (idle). We have disabled all

Hi All. I have two running servers (drbd primary, drbd secondary). When there is a problem with one of them we switch to the second one. Currently on the /dev/drbd0 (it has /xxx ext3 filesystem directly on it) we have some filesystem problems (after fsck -n). I would like to correct these errors but the filesystem should be unmounted first (I would like to avoid it if possible). Is there a way

Hi, Sorry for the need of the long winded email. Looking for some answers to the following. I am setting up a xen PV domU on top of a LVM partitioned DRBD device. Everything was going just fine until I tried to test the filesystems in the domU. Here is my setup; Dom0 OS: CentOS release 5 (Final) Kernel: 2.6.18-8.1.4.el5.centos.plusxen Xen: xen-3.0.3-25.0.3.el5 DRBD:

Hi All, I was hoping to pick someone''s brain about the best way of moving a Xen disk image (which has LVM''s inside of it) to a new block-device?  I have the target DRBD device ready but unsure what''s the best & safest way to do it. I was actually tempted to mount the Xen disk image in a dom0, and make it visible via loop devices and promote that DRBD node for

Hi, I have a server with Centos 5 + DRBD installed and is working fine, but when i run yum for udpate system show this error: Transaction Check Error: file /etc/drbd.conf conflicts between attempted installs of drbd-8.0.12-1.el5.centos and drbd82-8.2.6-1.el5.centos file /etc/rc.d/init.d/drbd conflicts between attempted installs of drbd-8.0.12-1.el5.centos and drbd82-8.2.6-1.el5.centos file

Hi, I've upgrade the kernel to the latest version (C5) and after the update the drbd is not being loaded at reboot time. My previous running kernel was 2.6.18-164.el5. I've checked the /lib/modules/ and /lib/modules/2.6.18-164.10.1.el5/weak-updates/drbd82/drbd.ko -> /lib/modules/2.6.18-164.el5/extra/drbd82/drbd.ko And /lib/modules/2.6.18-164.el5/extra/drbd82/drbd.ko exists 2004

Hi, I am trying to use drbd in my centos 5.4 but I keep getting errors. When I try modprobe -v drbd I receive insmod /lib/modules/2.6.18-164.el5PAE/extra/drbd/drbd.ko FATAL: Error inserting drbd (/lib/modules/2.6.18-164.el5PAE/extra/drbd/drbd.ko): Invalid module format.

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

Hej folks, I''m messing around with DRBD once again but with a new Xen 4.1.2 installation using the XL toolstack instead of the xend daemon. However, after getting my DRBD installed and a device operational, trying to create a domU using the drbd block device doesn''t want to work: xl create -c test.cfg Parsing config file test.cfg Unknown disk type: drbd My config has: disk

Thought this would be interesting for some people: Version 8.0.6 of DRBD comes with a nice script that adds support for a config like disk = [ ''drbd:r0,hda1,w'' ] This supports migration and live migration without having to take care of drbd yourself. Really nice feature. Read changelog on 8.0.6 on: http://svn.drbd.org/drbd/branches/drbd-8.0/ChangeLog Regards Dominik

Hello all, we have a new setup with xen on centos5.3 I run drbd from lvm volumes to mirror data between the two servers. both servers are 1U nec rack mounts with 8GB RAM, 2x mirrored 1TB seagate satas. The one is a dual core xeon, and the other a quad-core xeon. I have a gigabit crossover link between the two with an MTU of 9000 on each end. I currently have 6 drbds mirroring across that

Hi all, I want to do live migration of domains using DRBD block devices for synchronisation between the two Xen hosts with Xen 2.0.7. I''ve written a script ( block-drbd ) which binds / unbinds DRBD devices for specific domains (with DRBD, only one host can write on a drbd device at the same time). This script sets the current host as master (bind) or secondary (unbind) in a DRBD

Hi list, I installed two new servers to be our virtualization HA. This servers have CentOS 5.2, Xen 3.0.3, Drbd 8.2.6. The setup is ok, lvm drbd resources sincronizing, Guest VM running without any problem. My only doubt is that I can only use drbd resources inside guest vms when I specify the disk resource in vms config like this: disk = ['phy:/dev/VolGroup00/vappprtem01,hda,w' ]

Hi everyone, I´m using Citrix XenServer with DRBD. But something went really wrong, so I need a fresh Install.My only question is, how can I mount the DRBD partition? It is /dev/drbd1 , but if I try to mount it, I need to provide the filesystem type. Does anyone know what I have to do? I only need to copy some data from it, it doesn’t matter if it will be destroyed. I tried GFS as filesystem

Hi, we have 2 servers on centos5.2 in a cluster with the redhat cman in the configuration SERVER1 > LVM \ CMAN DRBD > XEN SERVER2 > LVM / For each xen we create a new local LVM on each node, put them in a drbd and install an os (debian 4 or ubuntu 8). The xens are running as pvm. Everything works fine since over 4 months now. But we have some performance-Problems: Writing

Dear collegues! I've got one question about drbd-kmdl packages. As I can see at $ rpm -qp --qf "%{DESCRIPTION}" kmod-drbd-8.0.16-5.el5_3.i686.rpm This package provides the drbd kernel modules built for the Linux kernel 2.6.18-128.4.1.el5 for the i686 family of processors. So, the question is - kmod-drbd is for kernel 128.4.1 (or build for this kernel version), but current kernel is
