Subject junk data of instance is not being deleted
Date Tue, 05 Feb 2013 10:23:57 GMT
Hi all,

Why the junk data of instance is not being deleted after the deletion of
instance

Here is my test case

My primary disk mount /mnt

1.Creating a template from snapshot

size of /mnt before creating template:16068 MB
size of /mnt when creating template:25058 MB(on process)
size of /mnt after registering template:16068 MB

2.Registered a instance using the template

*Before registering instance:*(size in MB)

3. Now,I had deleted the instance which i had registered.After deletion of
instance there is no much change in size (only 20 mb deleted) but
newly created file (1.5GB) is still existing
1497 603fadf0-2ab6-477d-afaa-dca4cd254e5d

4. Now i registered new instance with same template.It created a new file
and its size is only 22MB.If i delete the instance the new  file of
size22MB is deleted


Why is the flle size of 1.5 GB when i registered the instance for first
time is not being deleted from my storage
