<div>This doesn't sound like normal behaviour. It shouldn't matter which filesystem your tiebreaker disks belong to. I think the failure was caused by something else, but am not able to guess from the little information you posted.. The mmfs.log will probably tell you the reason.<br><br><br> -jf</div><div><br><div class="gmail_quote"><div>ons. 3. mai 2017 kl. 19.08 skrev Shaun Anderson <<a href="mailto:SAnderson@convergeone.com">SAnderson@convergeone.com</a>>:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

<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>
