[Linux-cluster] RHEL 6.1 Cluster with DRBD

[Goutam Baul]

Dear List,

 

We are trying to use filesystem that running on a DRBD device as one of the
resources of rgmanager. We have started the DRBD service, made the device a
Primary one and mounted the filesystems from a script which is given below
and have called the script as a script resource in the cluster.conf file.
The file is attached for your reference. Will you please comment whether
this way of using DRBD resource is good enough for using on a production
environment?

 

DRBD_MANAGE.SH file

 

#!/bin/sh

 

    start()

    {

        /etc/init.d/drbd start

        /sbin/drbdadm primary --force r0

        mount /dev/drbd1 /home

        mount /dev/drbd2 /var/spool/postfix

        RETVAL=$?

    }

 

    stop()

    {

         umount /dev/drbd1

         umount /dev/drbd2

         /sbin/drbdadm secondary all

         /etc/init.d/drbd stop

         RETVAL=0

    }

 

    status()

    {

         /etc/init.d/drbd status

         RETVAL=$?

    }

 

case "$1" in

        start)

                start

                ;;

        stop)

                stop

                ;;

        status)

                status

                ;;

        restart)

                stop

                start

                ;;

        *)

                echo $"Usage: $0 {start|stop|restart|status}"

                RETVAL=1

esac

exit $RETVAL
