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:

I'll be setting up a vSphere 4 environment hosting CentOS 5.4 on Netapp FAS and was curious how you guys are handling the automation of partition alignment within your linux guests. I'd like to use cobbler for dynamically creating kickstart scripts and wasn't sure if I could align my disk during install some how. Are there kickstart arguments to force the alignment on a 4k boundary?

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.

Hello, I have a couple of Dell 2950 III, both of them with CentOS 5.3, Xen, drbd 8.2 and cluster suite. Hardware: 32DB RAM, RAID 5 with 6 SAS disks (one hot spare) on a PERC/6 controller. I configured DRBD to use the main network interfaces (bnx2 driver), with bonding and crossover cables to have a direct link. The normal network traffic uses two different network cards. There are two DRBD

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 guys! I can?t find an answer in google, so my last hope is this mailing list. Story. I have two servers with same arrays. Servers connected by DRBD. I used ocfs2 as file system, also I used NFS4 to access to the ocfs2 drive. I do not have any idea, but the allocated descriptors in /proc/sys/fs/file-nr increasing every time while drive accessed. So after some time allocated descriptions over

Hi guys I have few problems with live migration ... and I need some professional help :) I have 2 xen servers ... CentOS 5.3 and I want to have a high available cluster Now let`s begin .... xen0: [root@xen0 ~]# fdisk -l Disk /dev/sda: 218.2 GB, 218238025728 bytes 255 heads, 63 sectors/track, 26532 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start

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

Hi. The short story... Rush job, never done clustered file systems before, vlan didn't support multicast. Thus I ended up with drbd working ok between the two servers but cman / gfs2 not working, resulting in what was meant to be a drbd primary/primary cluster being a primary/secondary cluster until the vlan could be fixed with gfs only mounted on the one server. I got the single server

I remember a thread many months ago where someone asked about a disaster recovery template or guide and several people on this list linked some really good content. I can't seem to find that thread now and neglected to make note of the links but I do recall that some of the guides came from a site that had many other "industry best practices" type guides. Any insight here or do you

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

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.

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

I'm looking to acquire a few new core switches for our network which would be a major upgrade from the cheap unmanaged things we currently have. Basically, just users, servers, and other simple network devices will be plugged into them but I'd like to start doing some testing with iSCSI for various non-production reasons. I have no allegiance to a particular vendor although I do have a

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

Not specific to CentOS but I know you guys would be really helpful anyhow. Basically, I have a file which has been editted in the past very similarly to the hosts file only now I want to use it as a hosts file and need to run some fancy sed to massage the data into shape. Currently, the data in the file is in the form of <ip address> <tab> <short hostname> <space>

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
