Disk resize issues

Hi @ Asim Malik,

Welcome to Microsoft Q&A Platform.

I understand that you received a notification indicating the VM disk size was increased to 256 GB, but it is still showing as 127 GB.

Please note that after resizing, updating the VM may take 10 minutes to complete. Once the resize operation finishes, restart the VM.

Allow up to 10 minutes for the updated disk size to be reflected in both Windows and Linux VMs. After restarting the VM, please check the disk size again. If it still shows the previous size, verify it using PowerShell

$disk= Get-AzDisk -ResourceGroupName $rgName -DiskName 
$diskName $disk.DiskSizeGB

I reproduced the same issue in my lab and observed the same behavior before restarting the VM.

I attempted to change the disk size from 127 GB to 256 GB and received a notification indicating that the disk was successfully updated. However, the disk size remained at 127 GB.

After changing the disk size, it remained the same and was not updated to 256 GB

After starting the virtual machine, the disk size was updated to 256 GB.

Note: To resize the VM, it must be in a deallocated state.

Hello @Asim Malik,

If you’ve attempted to increase your disk size from 127 GiB to 256 GiB but it still shows as 127 GiB when using the server, there are a few steps you may need to follow to ensure the new size is recognized:

1. Expand the Linux Filesystem: If the disk size is recognized but the filesystem hasn’t been expanded to utilize the new space, you may need to expand the filesystem as well. This can often be done using tools like growpart and xfs_growfs for XFS filesystems, or similar commands for other filesystem types.

2. Expand the volume in the Windows operating system
