Introducing Storage Tags
Hi
We need to introduce storage tags to "route" some specific workloads to dedicated storage.
The Problem is now that we already created quite a bunch of compute offerings in the GUI I'm not able to add a storage tag to them. Do we really have to recreate all of them or is there another way of getting the storage tag added to the existing offerings?
Regards
Andi

These are the arguments I have heard against "fixing" it.
- If you change it such that null means default, then what means don't care?
- If you're tiering storage, why wouldn't you tier the default storage?
It somewhat makes sense. The only real problem I've seen so far is Wido's case where there's no way to change the system offering's tags and system vms got put to premium storages but basically in this case system offering with no tags meant default tag instead of don't care tag. That's a contradiction to the usage to tags so it's a problem with initialization of tags.

Ok i try to explain and have one more question
We will have two Pri Storage, let's call them:
- default
- performace
And we have already around 30 compute offerings 1 to 8 cpu's with different ammounts of ram
All compute offerings have no storage tag
I can change the tag for the primary storage
So if the default storage also has no storage tag and the performance storage has tag=performance, will the existing compute offerings always reside on default storage and ONLY if a create a new offering with performance tag those instances will be deployed on performance storage?
Or does a empty tag mean just put it on some storage no mather of the storage tag?

Andi

The API call doesn't give that flexibility as well. I think you need to create new compute service offerings with the tags and upgrade the existing vms to these offerings (but be careful to tag the storages in the same cluster as currently we won't migrate the vm outside the cluster). If you want you can then delete the older offerings as well.
Why don't you try this for one of the vms and see how it goes. You can also share your exact scenario if my answer doesn't satisfy your requirements

So Storage Tags is a non -editable field in the UI . Once you have created a compute offering you can't modify the storage tag. I think but you can try using the update service offering API call (updateServiceOffering ) to edit the update the storage tag . Obviously you have to be the admin.

There's an api call to update service offerings:
http://incubator.apache.org/cloudstack/docs/api/apidocs-4.0.0/root_admin/updateServiceOffering.html
You could use something like cloudmonkey to update them...

Not officially supported, but you can tweak existing offerings directly in the Database
