Re: [Linux-cluster] Postgresql service on RHCS



I used a generic script resource instead of the supplied Postgres-8. It didn't seem to work, but then we needed 2 of them and not 1.

If you're using the init script, try using it as a script resource instead.

I am attempting to set up an active/passive failover environment for
postgresql-8.2.  I created a failover domain with 2 nodes, one of them
preferred, added a postgresql-8 resource and an IP address resource.  Now
when I set up a service I run into problems.  The idea is to have both the
postgresql-8 resource and the IP address resource within the service so
that it will move the floating IP to the other node in the domain and
start postgres on it.   The IP portion seems to work fine but postgresql
always fails.  I get these error messages:

Here are the relavent portions of cluster.conf:

               <failoverdomains>
                        <failoverdomain name="cdb6_pgsql" ordered="1"
restricted="1">
                                <failoverdomainnode name="cdb6"
priority="1"/>
                                <failoverdomainnode name="cdb5"
priority="2"/>
                        </failoverdomain>
                </failoverdomains>
                <resources>
                        <clusterfs device="/dev/mapper/gfsvol1"
force_unmount="0" fsid="36155" fstype="gfs"
mountpoint="/mnt/gfs" name="gfs1" options=""/>
                        <postgres-8
config_file="/var/lib/pgsql/data/postgresql.conf"
name="cdb6" postmaster_options=""
postmaster_user="postgres" shutdown_wait=""/>
                        <ip address="10.10.1.236" monitor_link="1"/>
                        <script file="/etc/rc.d/init.d/postgresql"
name="postgres"/>
                </resources>
                <service autostart="0" domain="cdb6_pgsql"
name="10.10.1.221" recovery="relocate">
                        <ip ref="10.10.1.236"/>
                        <postgres-8 ref="cdb6"/>
                </service>

I looked into the init script failing to return zero issue and I don't
think that is it.  My postgresql startup script doesn't even show that
there was an attempt to start it.  When setting up a postgresql-8 resource
I assume that 'config file' is the config file for postgres or is it the
startup script '/etc/rc.d/init.d/postgresql'?  Neither works for me.

Any tips would be greatly appreciated.
