Hi Ian,<br>
<br>
I don't think so, I have no-quorum-policy="ignore", which you should
for a 2 node cluster. Since most DRBD clusters are 2 node clusters,
I don't think this can be the problem...<br>
<br>
Thanks,<br>
<br>
Dirk<br>

<br>
I'm still struggling with this problem. Since my last
mail, I've<br>
simplified my setup: 1 DRBD resource with only 1 file
system resource. I<br>
normally have stonith in place & working, but this is
also removed for<br>
simplicity.<br>
<br>
Things that work as expected:<br>
- Pulling the dedicated drdb network cable. Location
constraint is<br>
created as expected (preventing promotion of the now
unconnected slave<br>
node). The constraint gets removed after re-plugging the
cable.<br>
- Rebooting the slave node / putting the slave node in
stanby mode. No<br>
constraints (as expected), no problems.<br>
- Migrating the file system resource. File system
unmounts, slave node<br>
becomes master, file system mounts, no problems.<br>
<br>
Things that do not work as expected:<br>
- Rebooting the master node / putting the master node in
standby mode.<br>
The location constraint is created, which prevents the
slave becoming<br>
master... To correct this, I have to put the old master
node on-line<br>
again and have to remove the constraint by hand.<br>
<br>
My setup:<br>
Ubuntu 10.04 running 2.6.32-41-generic / x86_64<br>
