Azure VM with alwayson AGs - expand data disk

Massimiliano Buschi 1

I have a three nodes SQL Server Alwayson cluster on Azure VM. I need to expand the data disk on all three nodes.

The disk is a stripe disk build during VM configuration.

Based on this:

https://learn.microsoft.com/en-us/azure/azure-sql/virtual-machines/windows/storage-configuration?tabs=windows2016#existing-vms

I should exted the disk following instruction. But in my environment Azure prevent me doing this as the storage is part of an HA solution.

How can I expand the disk without dismounting the HA solution?

Hello @Massimiliano Buschi ,

Thank you for reaching out to Micrososft Q&A platform.
Do you encounter any error while trying to expand the disks? What is the Storage HA solution? Can you expand the storage on the Storage Provider side for this configuration itself?

How was the solution deployed? Was it a template from a solution provider or have you done it all on your own?
As Prrudram already wrote... do you have an error message that shows the messages why you can't expand the storage... normally I would suggest only adding a new disk to that striped set of disks.
