----------------------------------------------------
Summary: Restarting cloudstack service with template download in
progress creates redundant entries in DB for systemVM template
Key: CLOUDSTACK-5536
URL: https://issues.apache.org/jira/browse/CLOUDSTACK-5536
Project: CloudStack
Issue Type: Bug
Security Level: Public (Anyone can view this level - this is the default.)
Components: Template
Affects Versions: 4.3.0
Environment: Latest 4.3 MS build
VmWare Host
Reporter: Pavan Kumar Bandarupally
Fix For: 4.3.0
My NFS secondary store has been migrated to Object Storage and an S3 secondary
Store is added. At this point the systemVM template will be downloaded to S3
store.
If we restart cloudstack-management service when download is in progress, the
current entry in template_store_ref which shows status as creating , persists
and a new entry will be created. If we restart the service once again another
entry is created persisting the older two entries as is.
"Removing leftover template routing-8 entry from template store table" is shown
in the traces but this doesn't take effect.
mysql> select template_id, store_id, store_role, state, install_path from
template_store_ref;

Expected:
-------------------
Upon service restart, template sync should reset the download of the template
and create only one entry for the systemVM template.
Actual:
---------
The older entry persists and new entry is created with status as Allocated or
Creating.
Note:
=========
This happens only with SystemVM template. General template downloads are
properly reset and only one entry exists for them.
