Greetings,
I have a four-node cluster on Ubuntu Focal with the following versions:
libknet1: 1.15-1ubuntu1
corosync: 3.0.3-2ubuntu2.1
pacemaker: 2.0.3-3ubuntu4.3
3.0.3 corosync-cfgtool was buggy - basically first version with
correctly working `cfgtool -a` is 3.1.5. If possible I would recommend
to update (either compile from source or use proxmox repo
http://download.proxmox.com/debian/pve/.

Each node is connected to two networks:
testras1:
eth0 10.1.8.24/26
eth1 192.168.21.227/24
testras2:
eth0 10.1.8.25/26 eth1 192.168.21.119/24
testras3:
eth0 10.1.8.66/26
eth1 192.168.21.13/24
testras4:
eth0 10.1.8.77/26 eth1 192.168.21.19/24
The totem section of corosync.conf on all nodes:
totem {
version: 2
cluster_name: BERND-RAS
# Disable encryption
secauth: off
interface {
linknumber: 0
#knet_transport: udp|sctp
#knet_link_priority: 0
}
interface {
linknumber: 1
#knet_transport: udp|sctp
#knet_link_priority: 1
}
transport: knet
}
and the nodelist section:
nodelist { node {
ring0_addr: 192.168.21.227
ring1_addr: 10.1.8.24
nodeid: 2036952047
name: testras1
}
node {
ring0_addr: 192.168.21.119
ring1_addr: 10.1.8.25
nodeid: 2036951939
name: testras2
}
node {
ring0_addr: 192.168.21.13
ring1_addr: 10.1.8.66
nodeid: 1921682113
name: testras3
}
node {
ring0_addr: 192.168.21.19
ring1_addr: 10.1.8.77
nodeid: 1921682119
name: testras4
}
}
On all nodes crm_mon shows all four nodes online:
Node List:
* Online: [ testras1 testras2 testras3 testras4 ]
and "corosync-cfgtool -s" shows the very same:
Printing link status.
Local node ID 2036952047
LINK ID 0
addr = 192.168.21.227
status:
nodeid 1921682113: link enabled:1 link connected:1
nodeid 1921682119: link enabled:1 link connected:1
nodeid 2036951939: link enabled:1 link connected:1
nodeid 2036952047: link enabled:1 link connected:1
LINK ID 1
addr = 10.1.8.24
status:
nodeid 1921682113: link enabled:1 link connected:1
nodeid 1921682119: link enabled:0 link connected:1
nodeid 2036951939: link enabled:1 link connected:1
nodeid 2036952047: link enabled:1 link connected:1
However, when I add a node that doesn't exist that changes:
node {
ring0_addr: 192.168.120.13
ring1_addr: 10.1.8.99
nodeid: 2036942833
name: testras5
}
Now "corosync-cfgtool -s" shows:
Printing link status.
Local node ID 2036952047
LINK ID 0
addr = 192.168.21.227
status:
nodeid 1921682113: link enabled:1 link connected:0
nodeid 1921682119: link enabled:1 link connected:1
nodeid 2036942833: link enabled:1 link connected:1
nodeid 2036951939: link enabled:1 link connected:1
nodeid 2036952047: link enabled:1 link connected:1
LINK ID 1
addr = 10.1.8.24
status:
nodeid 1921682113: link enabled:1 link connected:0
nodeid 1921682119: link enabled:1 link connected:1
nodeid 2036942833: link enabled:0 link connected:1
nodeid 2036951939: link enabled:1 link connected:1
nodeid 2036952047: link enabled:1 link connected:1
while everything else stays the same.
Why would "link connected" show 0 for one of the existing nodes but not
for the non-existing node (2036942833)? (All existing nodes can still
see each other) What am I missing?
