Hello all We are looking into ovirt for several weeks now and i have to say that it looks very promising. Our current environment is based on a lot off shell scripts and xen. We would like to move to ovirt but there are some things we would like to have working before moving. 1. using FC, san and clvm for storage 2. The ability to migrate virtual machines when we have to do maintenance on a

Hi, i am setting up a cluster of kvm hypervisors managed with libvirt. The storage pool is on iscsi with clvm. To prevent that a vm is started on more than one hypervisor, I want to use a lockmanager with libvirt. I could only find sanlock as lockmanager, but AFSIK sanlock will not work in my setup as I don't have a shared filesystem. I have dlm running for clvm. Are there lockmanager

Hi, I'm needing to expand a LUN on my EMC CX4-120 SAN. (Well I already had done it). On this LUN I had a PV of a cLVM VG. Know I need to run pvresize on it. Has anybody done this on a cLVM PV ? I'm trying to rescan the devices, but I can't "see" the new size. And, googling on it I can only find RHEL5.2 responses. Thanks in advance,

I'm desparately looking for more ideas on how to debug what's going on with our CLVM cluster. Background: 4 node "cluster"-- machines are Dell blades with Dell M6220/M6348 switches. Sole purpose of Cluster Suite tools is to use CLVM against an iSCSI storage array. Machines are running CentOS 5.8 with the Xen kernels. These blades host various VMs for a project. The iSCSI

Guys, I have setup my hard disc with 3 partitions: 1- 256MB on /boot; 2- 2GB on / for my dom0 (Debian 5.0) (eth0 default bridge for guests LAN); 3- 498GB exported with vblade-persist to my network (eth1 for the AoE protocol). On dom0 hypervisor01: vblade-persist setup 0 0 eth1 /dev/sda3 vblade-persist start all How to create a CVLM VG with /dev/etherd/e0.0 on each of my dom0s? Including the

Hi, I'm looking information about using libvirt with san (fiber channel) based storage and googling for a while i don't see anything about it. I send this email in order to get advices about libvirt and shared storage We use here, for 3 years now, 8 linux centos server connected to an hitachi FC SAN (multipath devices). Each server run Xen dom0 and use SAN LUNs to store Virtual machine

Hi - Is there someone around who successfully got cLVM on Debian/Lenny working? I was wondering if I was the only one facing problems with...

I have a problem with including extra data in a lattice graphic. I am trying to put some calculated values in an extra column of a boxplot. A minimal example should show what I am trying to do: foo <- data.frame( Treatment=rnorm(1:12,2),

I have a system with a large LVM VG partition. I was wondering if there is a way i could share the partition using nbd and have the nbd-client have access the LVM as if it was local. SYSTEM A: /dev/sda3 is a LVM partition and is assigned to VG volgroup1. I want to share /dev/sda3 via nbd-server SYSTEM B: receives A''s /dev/sda3 as /dev/nbd0. I want to access it as VG volgroup1. I am

Hi, the following szenario leads to a problem: I connect an CAPI channel to an AGI-Script per Manager API. This Agi script starts the MeetMe-Application. The Person on the Capi Channel is now able to speak with the other conferess in the MeetMe-Room. But if the CAPI channel hangs up, the busy tone is streamed into the MeetMe Room for several seconds, until the CAPI HANGUP-Signal is finally

Hi All :) I am currently involved in a project in which there is a SAN array (Sun Storagetek 2540) which exports LUNs for some servers with Centos 5.2 x86. I will be performing a migration to Centos 5.9 x86_64 in some time and am gathering needed info now :) I am trying to find the place in the OS where there is the information about LUN mappings to /dev/ devices. For example on array level I

Hello all. I would like to canvas some opinions on options for shared storage in a Xen cluster. So far I've experimented with using iSCSI and clvm which mixed success. The primary concern I have with both of these options is that there seems to be no obvious way to ensure exclusive access to the LUN/device to the VM I want to run. On a couple of occasions during my playing I've

Hello list I've installed cluster suite with 8 physical nodes, these are connected to a SAN using CLVM and AOE protocol. The cluster suite runs on the physical nodes/servers, in dom0. If I have to use GFS, where do I install this? What is the right approach to using GFS with Xen. I see 2 options: 1. I install GFS inside each domU (unprivileged domain, the actual VM). 2. I install GFS on

Please tell me if I am wrong : Xen needs LVM to perform domU snapshots and snapshots must be performed by dom0. By the way, a LVM volume group should not be used by more that one kernel at the same time. So if we use a SAN storage, one volume group should be activated on only one server and deactivated on the others. But if we do that, it should not be possible to perform live migration of

I have run into a problem using 'rsync' to copy files from local disk to a SAN mounted LUN / file-system. The 'rsync' seems to run fine and it reports no errors, but some files are corrupted (check-sums don't match originals, and file data is changed). So far, I have found this problem on both Solaris 9 and Solaris 10 OSes and on several different models of Sparc systems

HI Dom0 is CentOS 5.2, 64-bit, Xen version 3.2.1 and 3.2.2. I got Fiber SAN disk system and 2 servers and i am making shared LUN available to both servers. Then i got multipath layer running on both Dom0s and so Xen is seeing device-mapper file, instead of two /dev/sdX devices, then i have setup Xen domU (HVM Windows 2003) using /dev/mapper/sharedLUN as physical storage to my windows server.

Hi everybody! I've setup my dialplan so that if an extension dials *21*, that extension is added/removed as a queue member to a queue. (State toggled). But it would be great to get an "optical feedback" of that phone's state regarding the queue membership. Does someone know if it is possible to light up a LED under this szenario? Many thanks! Norbert

Hi all, We are running CentOS 5.2 64bit as our file server. Currently, we used GFS (with CLVM underneath it) as our filesystem (for our multiple 2TB SAN volume exports) since we plan to add more file servers (serving the same contents) later on. The issue we are facing at the moment is we found out that command such as 'ls' gives a very slow response.(e.g 3-4minutes for the outputs of ls

Hi, I am trying to build a rock solid XEN High availability cluster. The platform is SLES 11 SP1 running on 2 HP DL585 both connected through HBA fiber channel to the SAN (HP EVA). XEN is running smoothly and I''m even amazed with the live migration performances (this is the first time I have the chance to try it in such a nice environment). XEN apart the SLES heartbeat cluster is
