Marcus Sorensen created CLOUDSTACK-5853:
-------------------------------------------
Summary: 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.
