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 need the community''s opinion on the best way to use my storage SAN to host xen images. The SAN itself is running iSCSI and NFS. My goal is to keep all my xen images on the SAN device, and to be able to easily move images from one host to another as needed while minimizing storage requirements and maximizing performance. What I see are my options: 1) Export a directory through NFS.

I've been using OCFS2 on a 3 way Centos 5.2 Xen cluster for a while now using it to share the VM disk images. In this way I can have live and transparent VM migration. I'd been having intermittent (every 2-3 weeks) incidents where a server would self fence. After configuring netconsole I managed to see that the fencing was due to a heartbeat threshold timeout so I have now increased

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

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

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 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

Greetings. Is there an approved way to aggregate LUNs when using OCFS2? I have several 1TB LUNs I'd like to make into a single filesystem. Would I use something like Linux software raid? Brett

I'm trying to set up SAN-based shared storage in KVM, key word being "shared" across multiple KVM servers for a) live migration and b) clustering purposes. But it's surprisingly sparsely documented. For starters, what type of pool should I be using?

I've configured a text Xen system using ocfs2 1.4.1 as the shared filesystem to enable migration. So far the file based xen disk sharing is working well. Yesterday I tried to do a "xm save vm /ocfs2/vm.save" and I keep getting the following message: __ocfs2_file_aio_write:2185 ERROR: status = -14 The file created is only 9113 bytes long where it should be about 2 GB i.e.

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, According to this site, http://oss.oracle.com/osswiki/OCFS2/Roadmap cluster ware flock feature is available in (2.6.25) for Red hat 5.2 U2. But on download page of OCFS2 website I didn't find 2.6.25 version for 64 bit Red Hat Linux 5.2. Current download are only for Red Hat (kernel 2.6.18 ), from where I can download 2.6.25?

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, I''m curious about how you guys deal with big virtualization installations. To this date we only dealt with a small number of VM''s (~10)on not too big hardware (2xquad xeons+16GB ram). As I''m the "storage guy" I find it quite convenient to present to the dom0s one LUN per VM that makes live migration possible but without the cluster file system or cLVM

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,

Hi all, on my nodes I have another cluster manager running that takes care of fencing the node, is it safe to disable ocfs2 self-fencing? Details: I'm using ocfs2 over drbd in master/master aka primary/primary mode. In case of loss of network connectivity I would like to disconnect the drbd device, invalidate it and unmount the filesystem but ocfs2 reboots the node.... Is it possible to

Does anybody knows if is there a certified procedure in to backup a RAC DB 10.2.0.3 based on OCFS2 , via split mirror or snaphots technology ? Using Linux LVM and OCFS2, does anybody knows if is possible to dinamically extend an OCFS filesystem, once the underlying LVM Volume has been extended ? Thanks in advance Riccardo Paganini

Is Inotify **fully supported** by OCFS2? Thank you
