Subject [jira] [Created] (CLOUDSTACK-4907) [VMWARE]Volume Snapshot Entries are not deleted from DB when there is a failure to create Snapshot
Date Mon, 21 Oct 2013 10:26:43 GMT
Sailaja Mada created CLOUDSTACK-4907:
----------------------------------------

             Summary: [VMWARE]Volume Snapshot Entries are not deleted from DB when there is
a failure to create Snapshot
                 Key: CLOUDSTACK-4907
                 URL: https://issues.apache.org/jira/browse/CLOUDSTACK-4907
             Project: CloudStack
          Issue Type: Bug
      Security Level: Public (Anyone can view this level - this is the default.)
          Components: VMware
    Affects Versions: 4.2.1
            Reporter: Sailaja Mada
            Priority: Critical


Steps:
1. Configure Adv Zone with VMWARE ESXI 5.0 using Zone wide primary storage
2. Deploy a VM using user account 
3. Move Zone wide primary storage into maintenance. With this System Vm's  got migrated to
a xenserver host which is one more cluster in the setup.
4. Now tried to create ROOT volume snapshot of VMWARE user VM 
5. It failed saying "Failed to create snapshot due to an internal error creating snapshot
for volume 194"

But when looked at snapshot table. There is an entry created for this snapshot which is allowcated
state. There is no snapshot in the Secondary storage. Issue is only about the entry in DB
. This is getting displayed with listSnapshots from UI.

Expected results :  When there is a failure to create snapshot , we should cleanup the entries
created for that in the DB.
