Hi All,

I have problem with couple of VMS where is  Consolidation of disk keeps failing. Look into this in detail I cannot see any snapshot of the VM, But when i access the esxi host via SSH and vmfs/volumes/???/vm  I can see Delta.vmdk file very large.
I am getting below error on vCenter whihc trying to migrate the vm to other host or datastore.

Messahe from Esxihost : there is no more space for virtal disk

vmfs.volumes.4d11dcdf-???????/VMname    you might be able to contunie this session by freeing disk space on this relevant vloume.   the Datastore of the VM has more then 3TB free disk space.

I cannot found this artical https://kb.vmware.com/s/article/1005049  But does help to fix the problem.



Please can anyone help me to fix this problem.



Regards
Asif

Delta.vmdk file very large

that's what we call a snapshot!

Please have a read of my EE Article

HOW TO: VMware Snapshots :- Be Patient

I can work with you to try and resolve this issue.

Can you screenshot the VM Folder on the datastore, and also screenshot the VM Disk settings.

You shouldn't keep a single snapshot for longer than 72 hours because it's growing continuously and you might run out of space or it might impact the VM performance.

You need to delete it. I would turn off the VM before any process. And keep in mind that it might take hours to complete.

Follow this KB:

VirtualCenter does not show snapshots when snapshots exist

6. If there is sufficient space on disk to consolidate, take another snapshot in VirtualCenter to create a valid entry in the snapshot database.

7. Delete/delete all snapshots.
9. Restart the virtual machine.

Okay do the following...

Do you have any space left on the datastore ?

1. Power OFF the VM.

2. Take a new Snapshot.

3. Wait 120 seconds.

4. select DELETE ALL in Snapshot Manager.

WAIT and Be Patient!

5. Repeat for ALL VMs.

Hi Andrew,

Yes I can See there is 3TB free space on datastore, But when trying to Power off the VM I am getting below error, I tried to power off the VM using VCenter and from host as well.

Any Command line to force power off this VM.


Thanks

You need to free up disk space.

Do other VMs use this datastore ?

No more room for snapshot to grow.

Forcing the VM off, could corrupt it, if it's not already corrupted.

Maybe move or turn off another VM on the same datastore, will free up some space, and then quickly turn off this VM.

Andrew,

I just discovered that there was not space on LUN where VM provisioned. i have extend the LUN  to add space. But still I am unable to power off the VM, I will try using esxcli  and will update the post.

So there is no space on the datastore ?

It's possible that the Virtual Machine Disk is corrupted this can occur when snapshots run out of storage space.

Is the VM off ?

Your options...

1. Restart Network Management Agents on the host.

2. Restart vCenter Server service.

3. Connect directly to host and also check if the VMs is off.

the above will not affect other running VMs

and plus increase the space on LUN and then Datastore
