similar to: add a second file server for HA

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

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

Hi everybody, our university uses a Samba 3.6.9 server as PDC for a windows domain on a single physical server (external LDAP on another server is used). To get some redundancy up running a second physical machine was bought, which is exactly the same as the one running. Now I?m searching for the best way to get the job done. The first thought was to build a HA-Cluster with Corosync/Pacemaker

Hi all, As many of us, I'm trying to find a way to have a failover solution for a Samba domain. The actual choice has been (because of hardware cost) to have only 1 physical xen-based server (ubuntu 14.04) that do (dom0) : - DHCP server (LAN) - NTP server - firewall - proxy - DNS server Then 4 VMs running for: - Samba Domain controller - Samba Domain member (file server) - Apache2 server -

Only thing i see to do this is setup a clustert print server. I cant tell if its possible with samba.

Hi, I have two KVM hosts (CentOS 7) and would like them to operate as High Availability servers, automatically migrating guests when one of the hosts goes down. My question is: Is this even possible? All the documentation for HA that I've found appears to not do this. Am I missing something? My configuration so fare includes: * SAN Storage Volumes for raw device mappings for guest vms

A first start and introduction to CTDB you will find in the Wiki:

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'm Emiliano this is my first mail to samba mailing list. I have to solve this issue for a company. They need to had a folder, shared over CIFS for windows/mac clients, that is always available, also if the server who host it hang up or burn. I've looked for a lot of solution but i cannot find the right for me. Actually the company has two server, all running debian lenny as linux

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, 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.

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

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

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:

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 all, has someone worked with DRBD (http://www.drbd.org) for HA of mail storage? if so, does it have stability issues? comments and experiences are thanked :) Thanks, Rodolfo.
