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.
