<p>We noticed some odd behavior recently. I have a customer with a small Scale (with Archive on top) configuration that we recently updated to a dual node configuration. We are using CES and setup a very small 3 nsd shared-root filesystem(gpfssr). We also set
up tiebreaker disks and figured it would be ok to use the gpfssr NSDs for this purpose. </p>
<p><br>
</p>
<p>When we tried to perform some basic failover testing, both nodes came down. It appears from the logs that when we initiated the node failure (via mmshutdown command...not great, I know) it unmounts and remounts the shared-root filesystem. When it did this,
the cluster lost access to the tiebreaker disks, figured it had lost quorum and the other node came down as well.<br>
</p>
<p><br>
</p>
<p>We got around this by changing the tiebreaker disks to our other normal gpfs filesystem. After that failover worked as expected. This is documented nowhere as far as I could find. I wanted to know if anybody else had experienced this and if this is expected
behavior. All is well now and operating as we want so I don't think we'll pursue a support request.<br>
</p>
