---------------------------------------
> cannot deploy vm with differing service storage tag and data disk storage tag
> -----------------------------------------------------------------------------

> Key: CLOUDSTACK-5853
> URL: https://issues.apache.org/jira/browse/CLOUDSTACK-5853
> Project: CloudStack
> Issue Type: Bug
> Security Level: Public(Anyone can view this level - this is the
> default.)
> Components: Management Server
> Affects Versions: 4.2.0, 4.3.0, 4.4.0
> Reporter: Marcus Sorensen
> Assignee: Marcus Sorensen
>
> Create two storage pools, one with storage tag X, one with storage tag Y.
> Create a service offering with storage tag X.
> Create a disk offering with storage tag Y.
> Attempt to deploy a virtual machine with a datadisk, using given offerings,
> it fails.
> Deployment planner keeps a global object 'avoid'. It loops through each
> volume to be created, asking storage allocators for matching pools, passing
> this avoid object.
> First disk matches a pool or pools, adds ALL other pools to avoid object,
> then deployment planner attaches matching pools to a list for that disk.
> Second disk matches a pool, adds all other pools to avoid object, then
> deployment planner says "wait, matching pool is in avoid, can't use it".
> Oops. In fact, at this point ALL pools are in avoid (unless there are other
> pools that have both tags).
> Need to remove matching pool from the avoid set during each select phase.
