You would need to register a script to force umount the filesystem on the primary node and mount it on the node you are failing over to, it would be nice to be able to check if the filesystem is mounted before atempting to mount it, but I am not sure on how to do this)<br><br> Are you using a cross-over cable for the private interconnect?<br><br>Regards,<br>Luis<br><br>--- On <b>Fri, 6/27/08, alexandra.strauss@bayerbbs.com <i><alexandra.strauss@bayerbbs.com></i></b> wrote:<br><blockquote style="border-left: 2px solid rgb(16, 16, 255); margin-left: 5px; padding-left: 5px;">From: alexandra.strauss@bayerbbs.com

<br>
<br><font face="sans-serif" size="2">I refer to you hoping you may help me
with my problem... We have got an issur here and opened a SR at Metalink
but until now, we got no useful information in solving our problem. SR-Number
is 6855815.994...</font>
<br>
<br><font face="sans-serif" size="2">We wanted to protect 9i Single-Instance
Databases with 10g Clusterware following the third-party-tool approach.
There are no RAC-databases involved. But we want to achieve high availability
as the databases are business critical systems. We want to make the systems
able to </font>

to another machine in case of failure to keep downtimes low... To achieve
this we want to use OCFS2 for the filesystem. Relocate is done by script
with help of CRS.</font>
<br>
<br><font face="sans-serif" size="2">So we took two systems (byaz05 and byaz10)
and installed the following software: 10g CRS (10.2.0.3) and Oracle Software
9.2.0.8 and OCFS2 1.2.8</font>
<br>
<br><font face="sans-serif" size="2">We found the following Metalinknotes
and adjusted the heartbeat and timeouts for OCFS2: </font><font size="3">Metalink

<br><font size="3">We did no changes to the CRS/CSS default settings until
now.</font>
<br>
<br><font face="sans-serif" size="2">During HA-testing we watched unexpected
behaviour of the system. We deactivated the bond for private interconnect
and expected only one node to go down. But we faced both nodes going down.
As it seems to me one node was rebooted from OCFS2 and the other one from
CRS/CSS.</font>
