A co-worker was having an issue trying to reuse a VHD
that he previously used for another VM and was receiving an error. He then
decided to delete the VHD and move on with a fresh VHD however was now
receiving the following error:
Clicking on details yields the following:
deleting blob '/vhds/YourVHD.vhd”:
details, There is currently a lease on the blob and no lease ID was specified
in the request.
This is where I entered the story, this is “by design” behavior
and the error is expected if, the disk you are attempting to work with is truly
attached to an existing VM or if you are attempting to remove a VHD that
is still considered leased and/or visible through the portal as a disk or
an image in the Virtual Machines management interface.
So, let’s start off by checking to make sure that
this VHD is not attached to a VM.
In the Azure Management Portal, choose the Virtual Machines interface, and select Disks from the top right pane navigation.
Look at the Attached To column and
ensure it is blank, if it is not blank, then this is the issue.
let’s figure out whether it is attached to a VM or not, manually review your
instances interface and verify if the disk is attached or not. If it is and If
you no longer want the VM and want to reuse the disk, in the Instances interface on the top right pane
navigation choose the VM that it was attached to and select Delete from the “Drawer”
(bottom navigation ribbon). You will be presented with two options, Delete the attached disks and Keep the attached disks. Choose delete
if you want to be done with the VM and the VHD or keep if you want to try and
there is no instance with the disk you are referencing associated, Delete is
greyed / not selectable, and you still cannot create a VM from this disk then
keep reading. If removal is your goal then you should now be able to use the
Storage interface to delete the VHD.
here if your goal was to only remove the disk as you’re done.
However, if you decide you want to reuse the VHD and chose to keep it then read
You can first try to delete the disk entry.
*Note* This will NOT delete the blob from storage, it simply
removes the disk entry from the VM configuration.
To delete the Disk entry, navigate to Virtual Machines,
then choose Disks
on the top navigation. Highlight the disk in question and on the drawer
You will be presented with two options, Delete
the associated VHD and Retain
the associated VHD. Make your choice to retain it if you want
to reuse it or delete it if your goal is simply to be rid of it.
If you have chosen to keep it you will need to remove the lease
from the VHD itself if you want to reuse it. There are several tools out
there that will help with this, take a look at the Azure Storage Explorers page to see what is available. My choice
Explorer simply because I am familiar with it.
We are going to make a copy of our VHD here to work around this
- Start at the Azure Management Portal, choose the Storage
interface, then select the storage account that homes the VHD we
are working with. Now on the Drawer (bottom) choose Manage Access Keys
at the bottom, this will activate the information windows where you will
need to copy your Storage
Account Name and your Primary Access Key. Click the copy
icon at end of the entry field to copy each one and paste into OneNote
or your note keeper of Choice.
- Again I am
if you chose a different tool you will need to setup your account for that
tool. In Cloud Explorer go to Accounts
on the Home ribbon, choose New,
Blobs Account. Enter the storage account name you made
note of previously in the Name
field and supply your primary access key for the Secret Key
entry. Ensure that the Endpoint
drop down is set for General
(*.core.windows.net) and then everything
else below should be unchecked or blank and click ok.
- Now in Cloud
Explorer's left navigation pane, double click or expand
the storage account, select the vhds container and the in the
right navigation pane select the VHD in question. Right click
the VHD and select Rename and change
it a another name and click Ok. You
will receive an error stating again,
There is currently a lease on the blob and no lease ID was specified in
the request. Go ahead and click Ok to continue,
then click Refresh
on the Home ribbon or press (F5)
to refresh. You should now see a copy of the VHD with the name you chose.
- Almost done,
back over on the Azure Management Portal, choose
Machines interface, select Disks from the top navigation,
and then Create
from the drawer. Enter your new name for the disk, under VHD URL click
the folder and browse through to the location of your VHD copy, make
sure to check the selection The
VHD contains an operating system. Lastly select the
drop-down to specify if it is Windows
and then click the Ok
check mark at the bottom.
On the info drawer you will see Creating Disk YourDiskName, wait for
created disk YourDiskName.
Viola you now have a usable disk!
Go setup your Virtual Machine with your new disk, the process is
a little different to reuse a disk. On the Drawer, click New -> Compute
Machine -> From
Gallery -> My
Disks, and choose the new disk that you just created. From this
point forward creation is just like creating a Virtual
Machine from scratch.
I have tested this method of using an Azure
Storage Explorer and the rename method for creating a copies of disks
without detaching them from the VM and it works well.
