Note The steps for adding a disk for the Query Engine node are the same for all cloud environments (Marketplace and Enterprise). To replicate the semantic model on the newly added disk, restart the Kyvos services from Kyvos Manager or click the Re-Balance Aggregates option from the Kyvos Activity Monitor page. When upgrading or deploying a cluster without enabling the scaling permission role, you must add the required permissions for Query Engine disk scaling (increase, or decrease) to the role attached to the machine before performing the scaling. For clusters deployed with earlier releases that do not include the Query Engine disk scaling feature, you need to take a few additional steps. First, ensure that you grant the necessary permissions to the role assigned to the machine. Next, you must create a deployment user (for example, "kyvos") and add this user to the sudoers file to enable sudo access. This step is essential to enable Query Engine disk scaling in these environments. In If the new Kyvos cluster being is deployed with Query Engine disk scaling support in the enterpriseKyvos Enterprise, if and scaling-based permissions are selected applied where applicable, those permissions will be included in the created role. Otherwise, the disk scaling permissions will not be part of the created role.
