Extending Disk Space (Alma Linux)

In order to provide more disk space on the iDNA appliance, the underlying disk, partition and logical volume all have to be extended.

Extending the VMWare Disk

Extending the virtual disk is done using the VMWare host application. Here are examples for VMWare Workstation and vSphere:
 

Please restart the virtual appliance after adding the new disk. 

Extending the Hyper-V Disk

To extend the virtual disk, open the virtual machine properties and follow the steps below:

1. Navigate to IDE Controller 0, select Hard drive and click Add
   
   
   
2. Select New and finish the wizard:
   
   
   
   
3. After finishing the wizard click Ok to exit the Settings:
   

Please restart the virtual appliance after adding the new disk. 

Enlarging the Partition on an Existing Disk in the Appliance

Perform the steps in this paragraph if an existing virtual disk was enlarged. If a new disk was added, please skip this chapter and continue with "Creating a Partition on a New Disk in the Appliance" instead.

The easiest way to enlarge a partition in the appliance is to use the installed partition manager GParted. Please launch it using the Applications or Activity menu (or using the shell command "gparted").

Note: after starting GParted, you may be prompted with a message about whether the GPT partition should be resized to use all available space. Please confirm this change!

1. Right-click the partition that needs to be extended and click on Resize/Move
   
   
   
   
2. Draw the right border to the end, so that all fee space is taken up by the resized partition and click Resize
   
   
   
   
3. Confirm and apply the changes by clicking the green check-mark (Apply All Operations) in the tool bar
   
   
   

Creating a Partition on a New Disk in the Appliance

Perform the steps in this paragraph if a new virtual disk has been added to the system and its space should be made available to iDNA. If an existing disk has been enlarged, please continue with take a look at the chapter "Enlarging the Partition on an Existing Disk in the Appliance" instead.

The easiest way to enlarge a partition in the appliance is to use the installed partition manager GParted. Please launch it using the Applications or Activity menu (or using the shell command "gparted").

1. Select the new physical disk:
   
   
   
2. Select the unallocated space, open the Device menu and on click on Create Partition Table:
   
   
   
3. Click on Apply in the warning:
   
   
   
4. Select the new unallocated space, right-click and select New:
   
   
   
   
5.  From the Createas drop down menu, select PrimaryPartition and chose lvm2pv as File system (if needed, a Label can be defined):
   
   
   
6. Save your changes by clicking the apply button - also on the popup message
   
   
   

Adding the new Disk Space to Logical Volume Groups

Now that new disk space is available to the operating system, we need to make it available to the appropriate volumes inside their volume groups.

There are two main volumes that may need resizing:

• appdata (mounted to /opt/panagenda/appdata): mainly storage for DB design export files (DXL)
• pgdata (mounted to /opt/panagenda/pgdata): storage for Postgres database files

In this guide we will be using "pgdata" as an example, since it's the most likely volume that may need resizing. Whenever referred to the volume "pgdata", please look for the mountpoint "/opt/panagenda/pgdata" or the device name "cl-pan-opt_panagenda_pgdata".

1. Start a "Terminal" from the Applications/Activities menu, execute the command "ifa stop" and wait for the command to finish (this may take several minutes).
   
   
   
   
2. Start the "LVM Manager" (Logical Volumes Manager) from the Applications/Activities menu and select the volume group "cl-pan" on the left hand navigation bar.
   
   
   
   
3. Select the "pgdata" volume, right-click it and execute "Unmount"
   
   
   
   
4. The unmount process will reset the selection in the device list, so please select "pgadata" again.
   Tip: volumes can also be selected via the top navigation bar:
   
   
   
   
5. Right-click "pgdata", go to the edit sub-menu and select "Resize"
   
   
   
   
6. Drag the indicator to the right to add disk space to this volume and confirm with "Resize"
   
   
   Note: even though were are adding all disk space to one volume in this example, the new available disk space may be divided between multiple volumes. For more information on calculating disk space requirements, please refer to the Setup Guide.
   
   
   
7. Apply the changes using the check-mark symbol (Apply pending actions) in the top tool bar
   
   
   
   
8. After confirming the queue, you should see a success message like the one below and the new disk space will now be available to iDNA.
   
   
   
9. To complete the changes, we need to start iDNA Applications again. This can be done be executing "ifa start" or the "reboot" command in the Terminal window that should still be open from step #1.
