Subject [jira] [Commented] (CLOUDSTACK-9433) Change of VM compute offering with additional storage tags not allowed
Date Mon, 25 Jul 2016 08:45:20 GMT

Christian Meier commented on CLOUDSTACK-9433:
---------------------------------------------

Regarding: "Its far easier to migrate to service offering that has a tag VS updating an existing
service offering with a tag."

Yes, exactly 100% my opinion, I just want the api to exactly do the easier method and allow
me to migrate a VM to a service offering that has a storage tag while the currently associated
offering of the VM has no storage tag attached. It is just not allowed and throws the aforementioned
error, that new service offering should have tags as subset of current service offering tags.

If the current offering has no tags and you want to switch to one with a storage tag, it simply
stopped by this error which means only removing storage tags is possible.

> 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 if necessary.) More importantly, I think
the artificial restriction must be removed.
