Hello Andrew,
I do a new test, sorry you are right cibadmin is clever enough.
But why il have this:
on FC18:
<nodes>
<node id="-1062731267" uname="noeud1.apec.fr" type="normal"/>
<node id="-33445696" uname="noeud2.apec.fr" type="normal"/>
<node id="3232236029" uname="noeud1.apec.fr"/>
<node id="4261521600" uname="noeud2.apec.fr"/>
<node id="1" uname="noeud1.apec.fr"/>
<node id="2" uname="noeud2.apec.fr"/>
</nodes>
on FC17:
<nodes>
<node id="-1062731267" uname="noeud1.apec.fr" type="normal"/>
<node id="-33445696" uname="noeud2.apec.fr" type="normal"/>
<node id="2" uname="noeud2.apec.fr" type="normal"/>
<node id="1" uname="noeud1.apec.fr" type="normal"/>
</nodes>
My corosync conf is like this:
totem {
version: 2
secauth: off
cluster_name: cluster
interface {
ringnumber: 0
bindnetaddr: 192.168.1.0
ttl: 1
}
transport: udpu
}
nodelist {
node {
ring0_addr: noeud1.apec.fr
nodeid: 1
}
node {
ring0_addr: noeud2.apec.fr
nodeid: 2
}
}
Best regards.

1. stop the cluster on both nodes
2. on both nodes, run:
CIB_file=/path/to/cib.xml cibadmin -M -X '<cib crm_feature_set="3.0.7"/>'
3. start node1 and wait until it is elected as the DC
4. start node2
How can I execute the command "cibadmin -M -X '<cib crm_feature_set="3.0.6"/>'"
when the cluster is stopped ?
cibadmin is clever enough to talk directly to the contents of CIB_file
I started fc18 node, execute "cibadmin -M -X '<cib crm_feature_set="3.0.6"/>'",
started fc17 node, now the nodes talk but I have this.
on FC18:

on FC17:

<node id="-1062731267" uname="noeud1.apec.fr" type="normal"/>
<node id="-33445696" uname="noeud2.apec.fr" type="normal"/>

</nodes>
The nodes have two networks, 192.168.1.0/24 for external communication and
10.1.1.0/24 with bonding for drbd. Corosync used 192.168.1.0 with udpu.
Best regards.

Hello,
For a long time I used heartbeat/drbd for 2 nodes clusters with Fedora, I used
the internal crm of heartbeat not pacemaker.
I planned to upgrade from the fc17 to the fc18, but on fc18 heartbeat is
obsolete and I have to change to corosync/pacemaker.
For information the heartbeat fc17 package work fine on fc18 and the cluster
with a node fc17 and the other fc18 (without the firewall activated by default
!!!) work perfectly (The final configuration is to have the both node in fc18).
But the corosync/pacemaker do not work with a fc17 node and a fc18 node.
I have these packages.
drbd-pacemaker-8.4.2-1.fc17.i686
pacemaker-libs-1.1.7-2.fc17.i686
pacemaker-1.1.7-2.fc17.i686
corosync-2.3.0-1.fc17.i686
corosynclib-2.3.0-1.fc17.i686
pacemaker-cli-1.1.7-2.fc17.i686
pacemaker-cluster-libs-1.1.7-2.fc17.i686
pacemaker-libs-1.1.9-0.1.70ad9fa.git.fc18.i686
pacemaker-1.1.9-0.1.70ad9fa.git.fc18.i686
drbd-pacemaker-8.4.2-1.fc18.i686
pacemaker-cluster-libs-1.1.9-0.1.70ad9fa.git.fc18.i686
pacemaker-cli-1.1.9-0.1.70ad9fa.git.fc18.i686
corosynclib-2.3.1-1.fc18.i686
corosync-2.3.1-1.fc18.i686
The corosync config :
totem {
version: 2
secauth: off
cluster_name: cluster
interface {
ringnumber: 0
bindnetaddr: 192.168.1.0
ttl: 1
}
transport: udpu
}
nodelist {
node {
ring0_addr: noeud1.xxxx.fr
}
node {
ring0_addr: noeud2.xxxx.fr
}
}
quorum {
provider: corosync_votequorum
}
logging {
to_syslog: yes
debug: off
}
A short time after starting pacemaker I have this.
FC18 node:
Corosync Nodes:
noeud1.xxxx.fr noeud2.xxxx.fr
Pacemaker Nodes:
noeud1.xxxx.fr noeud1.xxxx.fr noeud2.xxxx.fr noeud2.xxxx.fr
<node id="-33445696" uname="noeud2.xxxx.fr" type="normal"/>
<node id="-1062731267" uname="noeud1.xxxx.fr" type="normal"/>
<node id="3232236029" uname="noeud1.xxxx.fr"/>
<node id="4261521600" uname="noeud2.xxxx.fr"/>
Why four nodes ?!? What are the nodes 3232236029 and 4261521600 ?
The same as the other two but stored as %u (unsigned int) instead of %d (signed
int).
This was a bug in older versions, you can work around it by specifying a
(small) nodeid in corosync.conf
FC17 node:
Corosync Nodes:
noeud1.xxxx.fr noeud2.xxxx.fr
Pacemaker Nodes:
noeud1.xxxx.fr noeud2.xxxx.fr
<node id="-33445696" uname="noeud2.xxxx.fr" type="normal"/>
<node id="-1062731267" uname="noeud1.xxxx.fr" type="normal"/>
On the FC17 I have some messages like this "error: cib_perform_op: Discarding update
with feature set '3.0.7' greater than our own '3.0.6'".
On the FC18 "warning: cib_process_replace: Replacement 0.5.4 from noeud2.xxxx.fr not
applied to 0.9.0: current epoch is greater than the replacement"
Pacemaker 1.1.7 and 1.1.9 are not compatible ?
This should provide some more information:
