Subject [jira] [Commented] (CLOUDSTACK-5097) Volumes created with snapshot (which in turn were created from the volumes having some random data) carry garbage data
Date Fri, 08 Nov 2013 07:25:19 GMT

ASF subversion and git services commented on CLOUDSTACK-5097:
-------------------------------------------------------------

Commit 3c350ab0b8ce1687a8f7e27e9e2f8e8d0fa68c47 in branch refs/heads/master from [~gauravaradhye]

CLOUDSTACK-4648: Fixed Snapshots test cases

Fixed following test cases:
1) test_01_volume_from_snapshot
2) test_03_snapshot_detachedDisk
3) test_07_template_from_snapshot

All three test cases are running successfully on XenServer but test cases (01 and 07) failing
on KVM due to a common issue.
Product defect logged for this: https://issues.apache.org/jira/browse/CLOUDSTACK-5097

test_03 is running ok on KVM too, the problem was - disk was not getting detached because
it was not unmounted before detaching. Added code to unmount the disk.

>  1. Create a virtual machine and data volume
>  2. Attach data volume to VM
>  3. Login to machine; create temp/test directories on data volume and write sample data
into it
>  4. Snapshot the Volume
>  5. Create another Volume from snapshot
>  6. Mount/Attach volume to another VM
>  7. Now compare the data on the volume, data should match
> The directories and files created earlier exist on the volume, but the data in the files
is garbage data instead of the data we have written into the volume earlier.
> Data is not matching.
