-------------------------------------------
Summary: Change of VM compute offering with additional storage
tags not allowed
Key: CLOUDSTACK-9433
URL: https://issues.apache.org/jira/browse/CLOUDSTACK-9433
Project: CloudStack
Issue Type: Bug
Security Level: Public (Anyone can view this level - this is the default.)
Affects Versions: 4.8.0
Reporter: Christian Meier
It is not possible to upgrade service offerings of a with no storage tags to a
offering with a storage tag.
The UI does not show a newly created Service Offering which has defined a
Storage Tag. If tried through cloudmonkey, the error reports :
"Unable to upgrade virtual machine; the new service offering should have tags
as subset of current service offering tags. Current service offering tags: [];
new service offering tags: [RootLun]"
While I understood the error message in the first place, it seems to me an
artificially introduced restriction which does not reflect real circumstances.
Usually users start without using a sophisticated tagging scheme. Later on
while already having instantiated VMs, and maybe getting additional primary
storage they want to refine their usage scheme. They start to create offerings
with storage tags. All existing machines cannot migrate to these new service
offerings but must be completely reinstalled.
(An automatic storage migration might be an additional option, but I think
still the ROOT admin can manually migrate the existing volumes neccessary.)
More importantly, I think the artificial restriction must be removed.
