Hi Marc,
you don't worry about the late of the your response, I read that you
were away from base......
I hope for some days of rest !!!
I want to relocate a service from one node to another, keeping the
same ip.
My cluster.conf is:
<?xml version="1.0"?>
<cluster config_version="5" name="cluOCFS2" type="ocfs2">
<cman expected_votes="1" two_node="1"/>
<clusternodes>
<clusternode name="clu01" votes="1" nodeid="1">
<com_info>
<syslog name="clu01"/>
<rootvolume name="/dev/sda2" fstype="ocfs2"/>
<eth name="eth0" ip="10.43.100.203"
mac="00:15:60:56:75:FD"/>
<fenceackserver user="root" passwd="test123"/>
</com_info>
</clusternode>
<clusternode name="clu02" votes="1" nodeid="2">
<com_info>
<syslog name="clu01"/>
<rootvolume name="/dev/sda2" fstype="ocfs2"/>
<eth name="eth0" ip="10.43.105.15"

<failoverdomain name="failover" ordered="1">

</failoverdomain>
</failoverdomains>

<ip ref="10.43.100.204"/>
<script ref="/etc/init.d/httpd"/>
</service>
</rm>
</clusternodes>
</cluster>
I am starting CMAN and RGMAN and everything is ok.

Hi Mark,
I have changed the service element from:
<service autostart="0" domain="failover" name="RHTTPD">
<ip ref="10.43.100.204"/>
<script ref="/etc/init.d/httpd"/>
</service>
to:
<service autostart="0" domain="failover" name="RHTTPD">
<ip ref="10.43.100.204"/>
<script ref="httpd"/>
</service>
but does not change the result, if I type clusvcadm -e RHTTPD the
service fails and the messeges log:
May 28 15:09:00 clu01 clurgmgrd[15046]: <notice> Starting disabled

a consideration, when rgmanager start, I should not ping the IP
address 10.43.100.204 ??
the result of tool rg_test is:

Hmm, you could extend logging by catching debug messages from rgmanager by
adding the line
local4.debug /var/log/rgmanager.log
to /etc/syslog.conf then restart syslog.
See if you can get more information from this file.

That's clear. This ip is already setup by the bootprocess. So it cannot be
setup.

Hi Mark,

</cluster>
and I added the line from your email:
local4.debug /var/log/rgmanager.log to /etc/syslog.conf
then I rebooted syslog but in the file rgmanager.log is logged only
when CMAN start,
while rgmanager is logged only in the file /va/log/messages but there
is no additional information.
Perhaps additional information can come from this tool, I hope:
rg_test test /etc/cluster/cluster.conf start service RHTTPD
Running in test mode.

Hi Stefano, the errors indicate, that the fd devices have not been configured correctly. udev is responsible for doing this in RHEL. You can workaround this issue by creating the following symlink: ln -s /proc/self/fd /dev/fd Hope this helps !

Hi Mark,
I changed two lines of the script /usr/share/cluster/ip.sh,
I have attached the script and the lines that I have changed are
immediately below the written CHANGED.
Now the service httpd start on the new ip address (10.43.100.204), and
if the nodo_1 goes down,
the service is relocated on nodo_2.
when I start the service, in the log messages I have:
Jun 3 13:56:58 clu01 clurgmgrd[14899]: <notice> Starting disabled
service service:RHTTPD
Jun 3 13:56:59 clu01 in.rdiscd[15391]: setsockopt
(IP_ADD_MEMBERSHIP): Address already in use
Jun 3 13:56:59 clu01 in.rdiscd[15391]: Failed joining addresses
Jun 3 13:57:00 clu01 clurgmgrd[14899]: <notice> Service
service:RHTTPD started
but despite this, the service httpd works.
I hope that the information that I am writing you, you are useful.
Bye.

Hi Stefano,
your changes are breaking the logic of the ip.sh resource agent.
for example:
your changes:
#CHANGED !!!
/sbin/ip -o -f inet addr | awk '{print $1,$2,$4}' | while read idx dev
ifaddr; do
isSlave $dev
if [ $? -ne 2 ]; then
continue
fi
idx=${idx/:/}
echo $dev ${ifaddr/\/*/} ${ifaddr/*\//}
#done < <(/sbin/ip -o -f inet addr | awk '{print $1,$2,$4}')
done
In the while loop, the redirection operator < <(cmd) provides the stdin for
the read command.
Please note, that the redirection requires the /dev/fd/XX files. (See my
previous mail)
To verify the redirection mechanism try something like this:
# cat < <(ls -l /etc/)
-Mark

Try to change the service element as follows:
<service autostart="0" domain="failover" name="RHTTPD">
<ip ref="10.43.100.204"/>
<script ref="httpd"/>
</service>
What tells you rgmanager now?
Also try to get used to the rg_test tool. That helps.
Try e.g. rg_test /etc/cluster/cluster.conf
