<p>Hello community, <br>
</p>
<p>yesterday evening one of our nodes was rebooted, but I have not
found out why. The engine only reports this:</p>
<blockquote>
<blockquote>
<p>24.11.2017 22:01:43 Storage Pool Manager runs on Host onode-1

[...]</p>
</blockquote>

<p>There is no crash report, and no relevant errors in dmesg. <br>
</p>
<p>Does the engine send a reboot command to the node, when it gets
no responds? Is there any other way to found out why the node was
rebooting? The node hangs on a usv and all other servers was
running well...</p>
<p>In the time, when the reboot was happen, I had a bigger video
compression job in one of the VMs, so maybe the CPUs got a bit
stressed, but they are not over committed. <br>
</p>
