Yes, it was a firewall issue, thanks!
Now I get proper messages on spread start and the IP configured in
wackamole is configured only on one of the nodes. However,when I
restart it, spread on the other nodes detects it but wackamole just
dies with no message in the logs instead of taking over the IP.
The only message I get in the logs is on wackamole starup:
953 No such interface
Which does not get in the way of bringing up the virtual interface.
Here is my wackamole config:
Spread = 4803 at 127.0.0.1
SpreadRetryInterval = 5s
Group = wack1
#prefer eth0:10.3.4.5/8
Prefer None
VirtualInterfaces {
eth0:10.80.116.41/23
}
Arp-Cache = 90s
Notify {
# Let's notify our router:
eth0:10.80.116.41/23
arp-cache
}
balance {
AcquisitionsPerRound = all
interval = 4s
}
mature = 5s
