Re: [Linux-cluster] problems starting cman



Hi,
Using tcpdump on one node I've started cman on the other one (failing again). It have captured one UDP packet:

[root inf18 openais]# tcpdump -nni eth1 'host 239.192.52.96'
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on eth1, link-type EN10MB (Ethernet), capture size 96 bytes
06:17:48.937509 IP 192.168.22.17.5149 > 239.192.52.96.5405: UDP, length 148

So should not be a multicast problem. Is not a routing problem because I'm just using eth1 and eth0 is disabled, so all traffic go across eth1.

On /var/lib/openais/ I found no core dump. What else could it be?

Regards,
Jordi

Hi,
I'm trying to start a two node cluster, but I can't start cman. If I run manually the join command it returns 141. (I don't know what dos this means) How can I know why it do not start? /var/log/messages does not give me any clue about it.

Here I copy all the messages I get. (I'm using a Fedora 7 with the latest packeges)

best regards,

Hi Jordi,

Check to make sure you have multicast enabled and if it really works.
We've seen some problems with some network switches not being set
for this properly.  Unfortunately, it varies from switch to switch.
Also, check to see if aisexec is failing and leaving a core dump.
This would be in the form of a "core" file in /var/lib/openais/
