This section explains how to view and manage the cluster resources created during Kyvos cluster deployment, and how to add or remove resources such as disks from the cluster using Kyvos Manager.

The Resources configuration page gives access to the resources created at the time of cluster creation. 

To view Resource Configuration, perform the following steps: 

• On the navigation pane, click Kyvos and Ecosystem > Query Engine Resources.
  The page displays information about the Query Engines and the resources allocated to them in the system.

Open

The page shows information about Maximum Heap Memory,  Off Heap Memory,  Additional Java Options, and Local Disks Path.

You can also set custom Java configurations for the Query Engine. To do this, you must use the arrows to increase or decrease Maximum Heap Memory, Off Heap Memory, and Additional Java Options.  

You can also set the Local Storage path for Query Engine and specify Allowed space (in %). To use the default local storage path, click the Add Default Path link. The default path for the local storage is displayed. 

Click the plus icon to add additional local storage paths. 

Adding Local Disks Path 

You can add Local Disks Paths for cuboid replication.

1. For this, click Add Local Disks Path.
   
   

   Open

   

    

2. On the Add Local Storage Path dialog box, select the Query Engine Instances on which you want to add the path. 

3. Provide Local Storage Path. You can add additional storage paths by clicking the plus icon. 

4. Specify the Allowed Space (%) on the disk.

5. Click Add. This adds the paths to all selected Query Engines. 

6. Optionally, modify the resources for a particular Query Engine by clicking the corresponding Modify button.

Adding data disk on Query Engines

Post-deployment, you can add a new data disk on Query Engines. 

To add a new data disk on Query Engines, perform the following steps. 
Add disk on Query Engine node.

1. For AWS, refer to AWS documentation. 

2. For Azure, refer to Azure documentation. 

3. For GCP, refer to GCP documentation. 

4. Mount the disk to the required directory. 
   For example, If you have two disks mounted on /data1 and /data2, and you want to add one more disk to the /data3 directory, in this case, you must enter the following command. 
   mount /dev/sdb1 /data3

5. Run the following commands to create an appropriate directory on a new directory and make the deployment (kyvos) user as owner:
   mkdir /data3/cube_local_cache
   chown kyvos:kyvos /data3/cube_local_cache

6. Run the following command to provide 755 permission to a new directory you have created. 
   chmod 755 /data3/cube_local_cache

7. Add local disk path.
