<div id="body8662426"><div class="section"><h4 class="sectiontitle">Function</h4><p>After a cluster is created, the number of required CN nodes varies with workloads. You can add or delete CN nodes as needed.</p>
|
|
<ul><li><p>Other O&M operations cannot be performed during CN addition or deletion.</p>
|
|
</li><li><p>Services need to be stopped during CN node addition or deletion. You are advised to perform this operation during off-peak hours or when services are interrupted.</p>
|
|
</li><li><p>If a fault occurs during CN node addition or deletion and the rollback fails, you need to log in to the backend to rectify the fault. For details, see "Cluster Usage" > "Failed to Roll Back CN Addition or Deletion" in <em>Troubleshooting</em>.</p>
