<p style="margin-bottom: 0.2in;">Hello All,<br>
<br>
I am developing a
master fail-over for my perceus cluster. <br>
<br>
<br>
from a long time
I am trying to implement DRBD in combination with heartbeat but it's
not working as it is suppose to be. <br>
<br>
I have two masters(
Primary and Secondary) and configured to provide fail-over to the
primary master . My heartbeat is running on a virtul ip which is on a
public network. Heartbeat is configured in this a way to provide
perceus as a Highly Available service and provide a private ip
fail-over on which my master is running . Everything is going
well but when fail-over takes place then nodes of the cluster shows <b>a
stale file system error</b>.<br>
<br>
I want to replicate all those
files from primary master to the secondary one which are providing
provisioning to the cluster nodes with the help of DRBD.
Now DRBD is replicating data but it's <b>not working with the
combination of heartbeat</b>. (Replicated disk should mount
automatically to the system which becomes primary when fail-over
takes place).<br>
<br>
Nothing happen with DRBD when I start heartbeat
I am doing everything manually. I am doing it as:<br>
<br>
<font size="4"><b>on
primary master:</b></font><br>
<font color="#666666"><span
style="background: transparent none repeat scroll 0%; -moz-background-clip: -moz-initial; -moz-background-origin: -moz-initial; -moz-background-inline-policy: -moz-initial;"><br>
#service
drbd start<br>
#drbdadm primary drbd1<br>
#mount /dev/drbd1
/replicated<br>
.<br>
.<br>
#umount /replicated<br>
#drbdadm secondary
drbd1<br>
</span></font><font color="#999999"><br>
</font><br>
<font size="4"><b>on
secondary node :</b></font><br>
<br>
<font color="#666666">#service
drbd start<br>
#drbdadm primary drbd1<br>
#mount /dev/drbd1
/replicated<br>
</font><font color="#999999"><br>
<br>
</font><br>
<br>
and
also there is still a stale file-system problem when I mount disks
manually as above to the other system after fail-over on the nodes of
the cluster .<br>
<br>
<font color="#999999"><br>
</font><font color="#000000">I
am seeking for any kind of help from you
guys...!<br>
<br>
Thanks...!<br>
