<p class=MsoNormal>Hi,<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I am getting the following error on a CentOS + DRBD + HeartBeat
setup:<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>When I stop the heartbeat service on the primary, for some
reason it cannot change the state of <o:p></o:p></p>
<p class=MsoNormal>drbd using the drbdadm command and I get the below error in
the log file:<o:p></o:p></p>
<p class=MsoNormal>State change failed: (-12) Device is held open by someone<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Manually running the “drbdadm secondary r0”
command does not work either.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>The file system is not mounted, running lsof does not show
any processes accessing the drbd device and <o:p></o:p></p>
<p class=MsoNormal>Fuser –mv returns nothing.<o:p></o:p></p>
<p class=MsoNormal>I also ran “grep drbd /proc/mounts” and that too
returned nothing, which tells me that the file system is un-mounted cleanly.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I’m going to install strace and see if that provides
me with any more information.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>After this the system just reboots. I googled around, went
through a whole bunch of mailing lists and did not see a reason as to why this
was happening and what can be done to avoid it. Is this just a bug with drbd or
heartbeat? Has anyone else seen and fixed this issue? When I googled, I did
come across people having a similar problem, but there was no mention of how it
was resolved. <o:p></o:p></p>
<p class=MsoNormal>Will upgrading to the latest drbd release solve it?<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>My setup:<o:p></o:p></p>
<p class=MsoNormal>CentOS 5.1<o:p></o:p></p>
<p class=MsoNormal>DRBD : 8.0.11-1<o:p></o:p></p>
<p class=MsoNormal>Heartbeat : 2.1.3-3<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I did not want to paste the drbd.conf file since the post
would be pretty long, but if it is needed then please let me know and I’ll
post that information as well.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I’m really running out of ideas, any help is greatly
appreciated. If anyone needs any more information from my end, then please let
me know and I’ll be happy to provide that too.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Thanks,<o:p></o:p></p>
<p class=MsoNormal>Nikhil<o:p></o:p></p>
