Hi, I think I''ve nearly evaluated all choices for which Virtualisation option to go to. Disappointed so far that I can''t get my PCI Cards visible in a guest, but never mind. On the same hardware (2 Gig RAM, AMD Athlon 64 3500 and a Fedora Core 8 i386 install), OpenVZ has a tendency to "freeze" up every now and again in SSH.KVM/Qemu seem to slow, Xen seems really

If you use the debian package 4.5.8 is can suggest you upgrade to 4.6.5 from buster or use my 4.6.6 Go through this changelog. http://metadata.ftp-master.debian.org/changelogs/main/s/samba/samba_4.6.5+dfsg-8_changelog My 4.6.6 is based on 4.6.5+dfsg-6 But i cant tell much jet about clustering setups. Except this page: https://wiki.samba.org/index.php/Clustered_Samba And

Hi We've got drbd going between 2 nodes:) ATM there is un-partitioned space on each node but (we think) they are syncing OK. It looks as though it has synced the whole partition (2GB) from the primary node 1 to the other node: node 1 smb1:/home/steve # cat /proc/drbd version: 8.4.4 (api:1/proto:86-101) GIT-hash: 3c1f46cb19993f98b22fdf7e18958c21ad75176d build by SuSE Build Service 1:

Hi list, I'm planning to setup a two-node "cluster" with file replication and samba. I've used drbd in the past with success, but now there isn't drbd on the official repo but only from elrepo. I want follow centos Line and than switch to GlusterFS. Said that, I'm new to GlusterFS. I have two hosts with a 2tb disk space for replica. I've ridden that glusterfs is

Hi, I want to upgrade from 8.0 to 8.1 but yum update does not work. Still 8.0 Probably the cause is that I compiled DRBD myself because it was not available for 8.0 when I set up the machine. Now yum update says: Error: ?Problem 1: cannot install the best update candidate for package drbd-pacemaker-9.11.0-1.el8.x86_64 ? - nothing provides pacemaker needed by

Hi, I have two machines in a cluster and want to create a high available samba share that connects to active directory for user information. The storage is DRBD and the filesystem is XFS. I'm using pacemaker as cluster software and using the lsb:samba init script. I connected both machines to my Windows AD server and tested this using winbind. winbind -u gives me all AD users which seems

Hi everyone, I need some help to setup my configuration failover system. My goal is to have a redundance system using Xen + DRBD + Corosync + Pacemaker On Xen I will have one virtual machine. When this computer has network down, I will do a Live migration to the second computer. The first configuration I will need is a crossover cable, won''t I? It is really necessary? Ok, I did it. eth0

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, 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.

Bonjour, J''aimerai mettre en place un cluster sous Xen ou XenServer avec 2 serveurs dell R 710. J''aimerai pouvoir monter un cluster en utilisant l''espace disque entiere des 2 serveurs cumulés ainsi que la mémoire Quelles sont vos retour d''expériences et vos configurations? Merci d''avance Cordialement Mat

I am running a two-node web cluster on OCFS2 via DRBD Primary/Primary (v8.3.8) and Pacemaker. Everything seems to be working great, except during testing of hard-boot scenarios. Whenever I hard-boot one of the nodes, the other node is successfully fenced and marked ?Outdated? * <resource minor="0" cs="WFConnection" ro1="Primary" ro2="Unknown"

Hello, I have setup a cluster system with drbd and heartbeat. I have samba running as a PDC. Everything works great when I am on server1 But when failover ocuurs I cannot seem to log on the domain anymore. I Have symlinks to my home share : /var/cache/samba , /etc/samba/ who are synced between 2 servers. Do I have to sync another files ?? greets John

Hi Does Sangoma 8-port card A108 support PCIe version 2.0 ? The card is here http://www.sangoma.com/products/hardware_products/digital_voice_and_data_networking/a108.html And we want to use 3 such cards in this motherboard because it has 3 PCIe slots of version 2.0 http://www.intel.com/products/desktop/motherboards/DX58SO/DX58SO-overview.htm Is this a good idea ? Do you have any experience

You could also use pacemaker to manage promoting the drbd device and mounting it with a dead master role as a dependency. Are you using anything to automatically promote the send slave already?

Hello, While working on heartbeat/pacemaker for a web service stored on drbd, I've thought what I've learnt could also be applied to samba in order to build a fault tolerant file server in our domain. While digging samba's doc, I've found that CTDB could also fulfill the need and is maybe better suited as it's samba-related. But on the other hand, I'd appreciate to begin

I wonder if someone can point me in right directions. I have two dell servers I setup iscsi so I have four 2 tb hard drives and i had used lvm to create one big partiton and share it using iscsi. How I go about assigning sections of iscsi for virtual hard drives . should go about assigning Should I export the whole 8TB as one iscsi and then use lvm to create smaller virtual disk. Or should I

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

Hi Everyone, We are setting up some READ-ONLY Samba servers, mounted from the same volume on a SAN. The files are media files to be played out by Windows Media Servers mounted on Win2003. Here are my thoughts about possible configurations, would someone mind letting me know what would the best option be? A) DNS Round Robin Have foo.domain resolve to 10.0.0.1, 10.0.0.2, 10.0.0.3. 10.0.0.1

Hi, I''m new in Xensource World. I have to work on Xen 3.1.2 hypervisor, I''ve done some searches on how to make Xen HA (not FT for the moment).The way that is come again and again is to make a cluster with Corosync, pacemaker, DRDB. I just want to now if there are others way to do Xen HA, and which is the best way in your opinion?I need something very stable and sustainable.
