[OSR-users] Relocate a service

Hi Mark,
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"
mac="00:15:60:56:77:11"/>
<fenceackserver user="root" passwd="test123"/>
</com_info>
</clusternode>
<rm log_level="7" log_facility="local4">
<failoverdomains>
<failoverdomain name="failover" ordered="1">
<failoverdomainnode name="clu01"
priority="1"/>
<failoverdomainnode name="clu02"
priority="2"/>
</failoverdomain>
</failoverdomains>
<resources>
<ip address="10.43.100.204" monitor_link="1"/>
<script file="/etc/init.d/httpd"
name="rhttpd"/>
</resources>
<service autostart="0" domain="failover" name="RHTTPD">
<ip ref="10.43.100.204"/>
<script ref="rhttpd"/>
</service>
</rm>
</clusternodes>
</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.
Starting RHTTPD...
/usr/share/cluster/ip.sh: line 583: /dev/fd/62: No such file or
directory
/usr/share/cluster/ip.sh: line 673: /dev/fd/62: No such file or
directory
Failed to start RHTTPD
/usr/share/cluster/ip.sh: line 583: /dev/fd/61: No such file or
