Adding a third drbd node<BR></FONT><BR></DIV>
<DIV></DIV><FONT size=2 face=sans-serif>I think you would need 8.3 and above for
node stacking, also where is the 3rd node is it local or at a remote
location.</FONT><BR><BR><FONT size=2 face=sans-serif>As far as upgrading
goes.</FONT><BR><BR><FONT size=2 face=sans-serif>I would have thought this would
be the best method.</FONT><BR><BR><FONT size=2 face=sans-serif>node1 =
Primary</FONT><BR><FONT size=2 face=sans-serif>node2 =
Secondary</FONT><BR><BR><FONT size=2 face=sans-serif>1) Stop DRBD on node2 (
Secondary ). Upgrade DRBD. Start DRBD on node2. Wait for DRBD to resync
data</FONT><BR><FONT size=2 face=sans-serif>2) Once data has synced. Demote
node1( Current Primary ) to secondary. Bring up node2 as your new
Primary.</FONT><BR><FONT size=2 face=sans-serif>2) node1 is now a secondary, so
your safe to stop DRBD, upgrade DBRD, bring back online as secondary and wait
for resync to occur.....</FONT><BR><BR><BR><BR><BR>

<BR><BR><BR><FONT size=2 face=Arial>Hi Everyone,</FONT><BR><FONT
size=3> </FONT><BR><FONT size=2 face=Arial>I currently have a two node
cluster using heartbeat in a Primary/Secondary mode. My question
is:</FONT><BR><FONT size=3> </FONT><BR><FONT size=2 face=Arial>Is it
possible to add a third node as a DR server (act as a second secondary) using
drbd version 8.2.5? Or will I have to upgrade to 8.3? These two
servers are live at the moment and would rather not have to be taking them
offline for a version upgrade. </FONT><BR><FONT
size=3> </FONT><BR><FONT size=2 face=Arial>However, if this is the case, is
there a "sure-fire" way to upgrading versions? </FONT><BR><FONT
size=3> </FONT><BR><FONT size=2 face=Arial>Any help would be much
appreciated.</FONT><BR><FONT size=3> </FONT><BR><FONT size=2
