Hello
I am having two shared volumes (GFS) one for postgres and
other to save files, so whenever i upload some files
Informations related to the files will be updated in the
postgres volume and actual file will be cpied to the Storage
volumes. Now database and file storage will be accessible
thorough a shared mechanism.
I had configured the failover cluster in such a way that
either node1 or node2 takes control when one of
the node fails (Active /Passive clustering).
My resource and service section of cluster.conf
<resources>
<script file="/etc/init.d/postgresql"
name="Postgresql"/>
<clusterfs device="/dev/pgsqlvg/datalv"
fstype="gfs" mountpoint="/pgsql" name="Postgres"
options=""/> <script file="/etc/init.d/vsftpd"
name="Vsftpd"/>
<clusterfs device="/dev/pgsqlvg/storage"
fstype="gfs" mountpoint="/home/ftpuser" name="Storage" options=""/>
<ip address="151.8.18.147" monitor_link="1"/>
</resources>
<service autostart="1" domain="postgres" name="Postgres">
<script ref="Postgresql"/>
<clusterfs ref="Postgres"/>
<script ref="Vsftpd"/>
<clusterfs ref="Storage"/>
<ip ref="151.8.18.147"/>
</service>
Two shared volumes:
*device="/dev/pgsqlvg/datalv" for postgres (<script
file="/etc/init.d/postgresql" name="Postgresql"/> for
database)
device="/dev/pgsqlvg/storage" for storing files (
<script file="/etc/init.d/vsftpd" name="Vsftpd"/>) for
loading files to storage.*
When ever a node takes control two volumes had to be mounted
and appropriate service for corresponding
volumes had to be started and this cluster had to be
accesible by an virtual ip ( <*ip address="151.8.18.147"
monitor_link="1"/>.*
For such situation whether my current conf is enough(
*adding all resources to a single service*) or is there any
actual configurations or appropriate procedures to achieve
these types of settings inorder to avoid single point of
failure.
Thanks for the help in advance
