DRBD, Xen, HVM and live migration
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.

Configuring Xen + DRBD + Corosync + Pacemaker
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

as promised description of my XEN HA setup
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:

PCI passthrough issue
Hello,
I''m facing a strange issue with network card PCI passthrough on my
openwrt test domU.
- With network PCI passthrough, DNS lookup failed for some domains
(exemple, google.com) but not for other (free.fr my ISP, or my domain
jbfavre.org). I can ping an IP address without any problem.
- Starting domU as a "normal" (ie without PCI passthrough), no problem.
As far as I can

Network isolation - PCI passthrough question
Hello,
I thinking about using PCI passthrough to dedicated a domU as firewall.
I understand PCI passthrough concept. When done, my domU will see
network card and the dom0 won''t any more. So I''ll be able to filter all
trafic from outside, since it will go through network domU.
Then, how will I be able to connect other domU (and maybe dom0) to the
network domU ?
In a normal way,

GlusterFS, Pacemaker, OCF resource agents on CentOS 7
Hi guys
I'm wondering if anyone here is using the GlusterFS OCF
resource agents with Pacemaker on CentOS 7?
yum install centos-release-gluster
yum install glusterfs-server glusterfs-resource-agents
The reason I ask is that there seem to be a few problems
with them on 3.10, but these problems are so severe that I'm
struggling to believe I'm not just doing something wrong.

samba4 + drbd + ctdb + failover
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:

Xen 3 High Availability ways
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.

Pacemaker bugs?
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
Hi!
I think I stumbled on at least two bugs in the CentOS 7.2 pacemaker package,
though I'm not quite sure if or where to report it.
I'm using the following package to set up a 2-node active/passive cluster:
[root at clnode1 ~]# rpm -q pacemaker

The installation is up-to-date on both nodes as of the

Problem upgrading from 8.0 to 8.1
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

KVM HA
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

How many guests
Hi Everyone,
I have a Dell R210 server which has a Xeon X3430 Quad Core CPU (2.4Ghz x
4) with 8GB of RAM. I intend to use the H200 controller in a RAID1 setup
How many VMs do you think I''d be able to run on this machine? Is 20
pushing it?
I''d say most (if not all) guests would be in PV mode.
Thanks

High Availability with Asterisk
Hi everybody,
what are the current options to get an Asterisk-system high available?
Using two servers as active/passive with DRBD, Pacemaker/Corosync works
very good, there are no quality issues of the voice quality, even not on
high loaded servers and no problems with a lot of small packages.
But for this you need two systems for every Asterisk-system, what is not
"economic" in any

Looking for Asterisk+Pacemaker+Corosync+DRBD example
I'm trying to setup a pair of FreePBX-4.211.64 boxes using Pacemaker,
Corosync, and DRBD.
All the examples I've found so far use Heartbeat, but Heartbeat is not in
the repositories and doesn't want to compile from source.
Does anyone have a working configuration they can share or a tutorial they
can point me to?
Also, what does drbdlinks bring to the party? Isn't just linking

Samba 3.6.9 - Redundancy (HA/BDC/DRBD)
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
