<p class="MsoNormal"><span style="font-size:12.0pt;font-family:"Arial",sans-serif;color:black">I’ve been setting up clusters on RHEL and SLES in Azure just fine for quite a while, but I’ve recently been asked to do the same thing on Ubuntu. Everything has
gone fine, but my one challenge is that I can’t get the softdog watchdog driver to load at boot time. In Azure we need to use softdog because there is no hardware watchdog available at this time. <o:p></o:p></span></p>

lines from the log files. Also, there is no other watchdog kernel module loaded that I can tell, and before I load the softdog module there is no /dev/watchdog device.</span></span><span style="font-family:"Arial",sans-serif"><o:p></o:p></span></p>
