Hi Tim,

Thanks very much for your email,

I have been advised to check the server status module before, which was a
very good point because I found out that despite the status_module was
activated on both nodes I still had to tweak some configuration in
httpd.conf to get the status page working on http://machine/server-status :

Apache Server Status for 192.168.0.103

Suhosin-Patch

My knowledge of corosync isn't deep enough, so bare with me if I am wrong,
but my guess is that the error you are talking about on line 174 :
+ wget -O- -q -L --no-proxy --bind-address=127.0.0.1 http://localhost:

happens because wget expects to see the status of the server at the URL
http://localhost, but the right URL would be http://localhost/server-status

As for Apache (apologies to the list for more apache log spam...)
access.log only shows lines like
127.0.0.1 - - [17/Sep/2011:13:19:33 +0100] "GET / HTTP/1.0" 200 322 "-"
"Wget/1.12 (linux-gnu)"

error.log only shows lines like :
[Sat Sep 17 13:19:32 2011] [notice] Apache/2.2.17 (Ubuntu)
PHP/5.3.5-1ubuntu7.2 with Suhosin-Patch configured -- resuming normal
operations
[Sat Sep 17 13:19:33 2011] [notice] caught SIGTERM, shutting down


Looks like I can only see the consequence of the Apache crash but not the
cause. Since I am running corosync in a test VM I am going to wipe it out
and restart from the top, because I really can't see why both nodes worked
like a charm for 2 weeks and then this happened all of a sudden after I have
rebooted the nodes. I remember playing around with crm configure edit before
it all happened, so maybe I have broken something by accident.


Thanks for your help
