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, I''m using Xen since few months and have a lot of fun with it in a production environnement. I''ve a question about how to change the CDROM (iso file) attachement to a guest ? My configuration is : Hypervisor running debian etch, no X env, Full VT support. When I want to install a new machine from iso CD, if more than one CD, I''m not able to switch to next CD.

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

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, 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, When I live migrate my centos guest from node1 to node2, I can ping the guest, but on node 2 if i do: xm console guest01 , I am not able to access it. When migrating back to node1 , I can access the console. What I noticed is, to access the console, the node ''s drbd resource/disk needs to be in primary status . Is it typical or only I am having this problem. Is there any

Hello Everyone, I recently had a question that got no responses about GFS+DRBD clusters for Xen VM storage, but after some consideration (and a lot of Googling) I have a couple of new questions. Basically what we have here are two servers that will each have a RAID-5 array filled up with 5 x 320GB SATA drives, I want to have these as useable file systems on both servers (as they will both be

Hi folks I deploy a two Dell PowerEdge T300 to test Virtualization with kvm+drbd+heartbaet. The KVM drbd and heartbeat work properly. However, I have doubt!! When the primary node has down, the secondary node start the VM that has original running on primary node... So, this required a full stop of hole system... This is not we wish here... Is there something way to live migrate VM from

Hello, We have successfully implemented a 2-node HA Xen cluster with DRBD, LVM and heartbeat, that can do live migration. I wrote up some details here: http://te.to/~ts1/xen_cluster.html I''d like to say thank you to all the people writing these great software. -- Takeshi _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com

Is there a way to do live migration with domU started on pygrub? I''m actually running xen 4.1 (debian squeeze) on two nodes with a drbd+lvm+corosync architecture. Live migration was fine till I put my DomU''s on pygrub. Has somebody experimented the same? Chris

Greetings. I''ve reviewed the list archives, particularly the posts from Zakk, on this subject, and found results similar to his. drbd provides a block-drbd script, but with full virtualization, at least on RHEL 5, this does not work; by the time the block script is run, the qemu-dm has already been started. Instead I''ve been simply musing the possibility of keeping the drbd

I've got a CentOS 5 server that I want to migrate over into a virtualized instance. The problem is I need to minimize downtime so was trying to figure out a way to "live" clone the original. Initially, I thought I could do this via exporting an iSCSI target from the virtual host, create a MD raid 1 array on the C5 server, wait for it to sync, then shutdown the physical server and

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' ]

Hello, Currently it seems that the drbd disk type with Xen''s XL toolstack (vs XM) to get the automatic promotion/demotion behavior of drbd devices is not supported. Is there something I can tweak with the block-drbd script to get this to work?

Hi Everyone, I am going to get a storage server which will be connected to my Xen hosts via iSCSI/Ethernet. I wish to use LVM for the DomU disks. The storage server will have a RAID10 array, and 2 Xen hosts will connect to this (Each will have a 50% share of the RAID10 array, space wise). What is the best way to go about this? Should I: a) Split the RAID10 array into 2 partition on the

Hi all. I am currently working for a hosting provider in a 100+ linux hosts' environment. We have www, mail HA solutions, as storage we mainly use NFS at the moment. We are also using DRBD, Heartbeat, Corosync. I am now gathering info to make a cluster with: - two virtualization nodes (active master and passive slave); - two storage nodes (for vm files) used by mentioned virtualization nodes
