> Key: CLOUDSTACK-8808
> URL: https://issues.apache.org/jira/browse/CLOUDSTACK-8808
> Project: CloudStack
> Issue Type: Bug
> Security Level: Public(Anyone can view this level - this is the default.)
> Components: Secondary Storage
> Affects Versions: 4.4.4, 4.6.0
> Environment: Seen on NFS as sec storage
> Reporter: Remi Bergsma
> Assignee: Rajani Karuturi
> Priority: Blocker
>
> We noticed all of our templates are downloaded again as soon as we restart SSVM, its Cloud service or the management server it connects to.
> A scan done by the SSVM (listvmtmplt.sh) returns the template, but it is rejected later (Post download installation was not completed) because (Format is invalid) due to missing virtualSize property in template.properties.
> The initial registration did succeed however. I'd either want the registration to fail, or it to succeed. Not first succeed (and spin VMs without a problem) then fail unexpectedly later.
> This is the script processing the download:
> services/secondary-storage/server/src/org/apache/cloudstack/storage/template/DownloadManagerImpl.java
> 759 private List<String> listTemplates(String rootdir) {
> 760 List<String> result = new ArrayList<String>();
> 761
> 762 Script script = new Script(listTmpltScr, s_logger);
> 763 script.add("-r", rootdir);
> For example this becomes:
> ==> /usr/local/cloud/systemvm/scripts/storage/secondary/listvmtmplt.sh -r /mnt/SecStorage/ee8633dd-5dbd-39a3-b3ea-801ca0a20da0
> In this log file, it processes the output:

> Confirmed the virtualsize is missing. But why is this successfully registered in the first place?
> Steps to reproduce:
> - register template
> - have it install successfully
> - check templates.properties file
> sometimes virtualsize is missing
> - if it's there, remove it
> - restart cloud service on SSVM
> - the download will start again
> in my case virtualsize is still missing
> - this becomes an endless loop.
