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

Hello all fellow CentOS users! I have a working xen setup with 3 paravirt domUs and one Windblows 2003 fully virt domU. There are to virtual networks. As far as I can tell in the paravirt Linux DomUs I have gigabit networking, but not in the fully virt Windows 2003 domU.... Is there a setting for this, or is it not yet supported? I run xen-3.0.3-64.el5_2.3 Kind regards, Coert

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?

Hello all, I have been running xen for a while now with two interfaces: dummy0 for host only communication, and eth0 for the outside network. my script looks like this: (/etc/xen/scripts/network-bridge-more) ------------------------------------------------------------------ #! /bin/sh dir=$(dirname "$0") "$dir/network-bridge" "$@" vifnum=0 netdev=dummy0

Hello all, Windows......................... I have installed a Windows Server 2003 fully virt domU with the GPLPV drivers. The network settings reset on every restart of the domU. Weird STOP errors keep popping up.... Was I naive to think you can run a Windows server on Xen? Are any of you guys doing it successfully? Am I better of just installing windows server 2k3 on bare hardware? Just

Hello all, About a year ago I set up a mail server on CentOS using this howto: http://wanderingbarque.com/howtos/mailserver/mailserver.html I managed to add amavisd-new with clamav and spamassassin. It runs very well, but it runs on CentOS 5.2, and if I try to upgrade, amavisd-new and clamav break. we are now also at the point where a backup mx will need to be implemented. If necessary I am

Hello all, Got myself the Linux Advanced Routing & Traffic control book http://lartc.org/howto/ All the commands in the guide do not survive reboots. Could someone point me in the right direction, where I can find CentOS/Redhat specific documentation on the whole /etc/sysconfig/network* setup? Kind regards, Coert Waagmeester

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 all, Got samba with AD integration and extended ACL up and running.

Hi list, I setup on 2 Xen Dom0s drbd/gfs a logical volume, this works as primary/primary so both DomUs will be able to write on them at the same time. But I dont know how to mount them from my domUs, I can see them with fdisk -l. The partition is /dev/xvdb1 SHould I install gfs on domUs and mount them on each as gfs partitions? [root@p3x0501 ~]# fdisk -l Disk /dev/xvda: 5368 MB, 5368709120

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

Hello all! I have a samba server as a member of a domain with trust relationships to two other domains. Samba is configured with: winbind use default domain = yes winbind separator = + so the domain samba is member of does not use the seperator, but the other 2 domains do. If I change this to winbind use default domain = no ,will I have to update all the ACLs on the filesystem to include

Hello all, I have yesterday after some typos, sent my ext3 RAID5 array to the void... I want to recreate it now, but I read on http://wiki.centos.org/HowTos/Disk_Optimization that you can optimize the filesystem on top of the RAID. Will this wiki article be exactly the same for XFS? Is it worth the trouble to also create an LVM volume on the RAID array? Regards, Coert

Hello all, Firstly, I have checked on google, and there are indeed howtos on this subject. Have any of you done this or something similar on CentOS? If so, could you send me the configs maybe? How can I find out if the centos version of samba supports extended ACLs? I ran a modinfo xfs, and XFS supports it. I want to set up a samba server that authenticated to AD. I have that up and running,

Hello all, I''ve just installed a new dom0 with openSUSE 11.3 (x86_64) and I''m seeing domUs crashes when reading from disks.

Hello all, Have installed eclipse 3.5 x86_64 from the eclipse site, with CDT and QT integration. I am just starting to learn C++ but I would like to know how to set up the ability to compile for 32 bit as well? At the moment I am googleing this as well. Regards, Coert

Hi all, In threads posted by I believe Jonathan Tripley I promised to post my new XEN HA setup. Hope it can be of some use to some people. In this particular case I''m forced to use SLES 10SP3 with XEN 3.2, which excludes the possibility of using things like cLVM (which I don''t think I need anyway). So: Storage: I use two HP ML370 G5 machines with DRBD and heartbeat on
