<div>What did the smb log claim on the nodes? Should be in /var/adm/ras, for example if SMB failed, then I could see that CES would mark the node as degraded.</div>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D;mso-fareast-language:EN-US">Thanks. Some of the node would just say “failed” or “degraded” with the DCs offline. Of those that thought they were happy to host
a CES IP address, they did not respond and winbindd process would take up 100% CPU as seen through top with no users on it.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D;mso-fareast-language:EN-US">Interesting that even though all CES nodes had the same configuration, three of them never had a problem at all.<o:p></o:p></span></p>

should have been enough resiliency to cope.<o:p></o:p></span></p>
