    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 &amp; 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>
