Subject [jira] [Created] (CLOUDSTACK-5193) [Hyper-V] VHDs not deleted post VM destroy and expunge
Date Mon, 18 Nov 2013 09:57:23 GMT
Sowmya Krishnan created CLOUDSTACK-5193:

             Summary: [Hyper-V] VHDs not deleted post VM destroy and expunge
                 Key: CLOUDSTACK-5193
             Project: CloudStack
          Issue Type: Bug
      Security Level: Public (Anyone can view this level - this is the default.)
          Components: Management Server, Storage Controller
    Affects Versions: 4.3.0
         Environment: Hyper-V
            Reporter: Sowmya Krishnan
            Priority: Critical
             Fix For: 4.3.0

Create a VM with local/shared storage offering.
Destroy the VM with expunge = true or destroy and wait for VM to expunge.

Although VM is destroyed and volume is marked removed in cloud DB, it is not removed from
the hypervisor disk. I don't find .storage.command.DeleteCommand being triggered as part of
the Destroy VM.

As seen below, vhd corresponding to VM i-2-27-VM still resides in the host:

C:\Users\Public\Documents\Hyper-V\Virtual hard disks>dir /W "ROOT-27.vhd"
 Volume in drive C has no label.
 Volume Serial Number is 7C16-4C80

 Directory of C:\Users\Public\Documents\Hyper-V\Virtual hard disks

               1 File(s)  3,120,370,688 bytes
               0 Dir(s)  892,863,770,624 bytes free

C:\Users\Public\Documents\Hyper-V\Virtual hard disks>

SQL output for the destroyed VM volume:
