Increase disk size with reattach OS disk persistence

If the stateful node uses reattach persistence for the OS disk, you can resize the existing disk directly.

1. Pause the stateful node

   In the Flexera console, pause the stateful node.
   
   

2. Resize the disk in Azure

   In the Azure portal:

   • Go to Disks

   • Select the OS disk attached to the stateful node

   • Select Custom disk size

   • Increase the disk size and save the changes
     
     

3. Update the performance tier

   If required, change the disk performance tier to match the new size.
   
   

4. Resume the stateful node

   Return to the Flexera console and resume the stateful node.

Increase disk size with on‑launch OS disk persistence

If the stateful node uses on‑launch OS disk persistence, you must create a new disk and swap it.

1. Create a snapshot

   In the Azure portal, take a snapshot of the OS disk used by the running stateful node virtual machine.
   
   

2. Create a new disk

   Create a new disk from the snapshot and increase the disk size as needed.
   You may also need to update the disk performance tier.
   
   

3. Pause the stateful node

   In the Flexera console, pause the stateful node.
   
   

4. Swap the OS disk

   In the Flexera console:

   • Select Actions > Swap OS disk

   • Choose the resource group and the new disk name

   • Select Update & resume

After completing these steps, the stateful node runs with the increased OS disk size. The disk configuration remains consistent with the selected persistence model.
