<p class="MsoPlainText">From your email "<b>The solution to my particular problem was an improperly formatted haresources file for Heartbeat. Heartbeat was commanding DRBD to unmount/detach a filesystem when a key service was not yet shut down. Once I cleared
that up not only did the messages go away but failover occurs within 2-3 seconds!</b>", it sounds like the issue was occurring in case of switchover the machines.<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">In my case also, the issue "<b>DRBD device held open</b>" is occurring when I am trying to do failover and stuck in device held open issue. I went through the
<b>"/etc/ha.d/haresources"</b> file and found that the "<span style="color:#1F497D;background:yellow;mso-highlight:yellow">drbddisk::drbd0 LVM::vgdrbd0 Filesystem::/dev/vgdrbd0/mysql::/var/TKLC/elap/drbd/mysql::ext3</span>" is unmounting/detaching a file system.<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">Are you talking about the unmount/detach related to the one highlighted in

<p class="MsoPlainText">Hi Satyajit,<o:p></o:p></p>

<p class="MsoPlainText">this is an instace of thread confusion. The haresources answer was not actually directed to you, but instead belongs to an old thread that happens to have the same subject.<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">The proposed solutions applies to setups with the obsolete heartbeat cluster stack, which you are (hopefully) not using, so this will likely not help your case.<o:p></o:p></p>
