Paul Angus commented on CLOUDSTACK-6254:
----------------------------------------

Using 4.2.1:
Here is the linked file on the secondary storage VM

root@s-1-VM:/var/www/html/userdata# ls -l
total 1
lrwxrwxrwx 1 root root 113 Mar 14 18:06 4d1381d2-5eb7-4585-953d-7d5470587a70.vhd -> /mnt/SecStorage/2502671f-280b-3b17-9d3d-146db788fa9f/template/tmpl/2/202/7df99541-a771-4a45-9334-4456d0b5410c.vhd

during the night the flowing runs:

2014-03-14 23:56:04,398 DEBUG [cloud.storage.StorageManagerImpl] (StorageManager-Scavenger-1:null)

}

And the link on the SSVM and the file in secondary storage both are removed

> In 4.2.1,  the template VHD file gets removed from the template directory after it has
been downloaded. This issue occurs when the secondary storage server is cleaning up the symlink
in /var/www/html/. 
> Along with removing the symlink, the actual vhd is also removed. 
> It looks like maybe the SSVM is seeing the template as a volume and thinks that it is
removing a hard link.
