<p class=MsoNormal><font size=2 face=Arial><span lang=EN-IE style='font-size:
10.0pt;font-family:Arial'>I’m running a DRBD/HA (Active/Passive using
serial cable ) config that seems to be working ok but I have a query on whether
what I am seeing is expected behaviour or not.</span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span lang=EN-IE style='font-size:

<p class=MsoNormal><font size=2 face=Arial><span lang=EN-IE style='font-size:
10.0pt;font-family:Arial'>H1 & H2 are 2 identical dell servers running
RHEL4, Heartbeat & DRBD. Failover works ok and the disk mounts fine on both
servers.</span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span lang=EN-IE style='font-size:
10.0pt;font-family:Arial'>As a test I have been pulling the power/ network
cables / power off switches etc.</span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span lang=EN-IE style='font-size:
10.0pt;font-family:Arial'>My query is around the following.</span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span lang=EN-IE style='font-size:
10.0pt;font-family:Arial'> </span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span lang=EN-IE style='font-size:
10.0pt;font-family:Arial'>If H1 is active and I pull the network cable H2 takes
over fine mounts the disk and all is well.</span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span lang=EN-IE style='font-size:
10.0pt;font-family:Arial'>However when I reconnect the network cable into H1, I
get an error and at least 1 drbd process shuts down on H1. checking /proc/drbd
on H2 now shows Primary/Unknown and on H1 its Unknown/Secondary.</span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span lang=EN-IE style='font-size:
10.0pt;font-family:Arial'>I then need to do a failover and restart drbd on both
nodes to get back to a Primary/Secondary setup.</span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span lang=EN-IE style='font-size:
10.0pt;font-family:Arial'>What I thought should happen would be that DRBD on H1
goes, oh crap, I’m not the main man any more… better sync up with
the other primary.</span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span lang=EN-IE style='font-size:

<p class=MsoNormal><font size=2 face=Arial><span lang=EN-IE style='font-size:
10.0pt;font-family:Arial'>I wont go posting configs etc until I find out if
this is wrong or not.</span></font></p>
