-------------------------------------------
Summary: Restrict the number of managed SRs and datastores
Key: CLOUDSTACK-10336
URL: https://issues.apache.org/jira/browse/CLOUDSTACK-10336
Project: CloudStack
Issue Type: Bug
Security Level: Public (Anyone can view this level - this is the default.)
Components: VMware, XenServer
Affects Versions: 4.11.0.0
Environment: XenServer and VMware
Reporter: Mike Tutkowski
Fix For: 4.12.0.0
For managed storage, each time a virtual disk is created, a new SR is created
(when on XenServer) or a new datastore is created (when on VMware).
XenServer 6.5 can support around 500 - 600 SRs per compute cluster while VMware
can support 256 datastores per compute cluster.
CloudStack has never had the ability to limit the number of SRs or datastores
it creates when using managed storage (the admin has needed to pay attention to
this via some other process outside of CloudStack).
This code aims to address the main use cases in CloudStack that can create SRs
or datastores and fails the applicable operations if no more SRs or datastores
can be created (based on a new cluster-scoped setting that specifies how many
SRs or datastores the admin is OK with CloudStack creating).
