             Summary: [doc] Document Heterogeneous Secondary Storage Not Supported in Region
                 Key: CLOUDSTACK-5845
                 URL: https://issues.apache.org/jira/browse/CLOUDSTACK-5845
             Project: CloudStack
          Issue Type: Bug
      Security Level: Public (Anyone can view this level - this is the default.)
          Components: Doc
    Affects Versions: 4.2.0
            Reporter: Radhika Nair
            Assignee: Radhika Nair
             Fix For: 4.3.0


Current implementation cannot have two zones, one using NFS secondary, the other using S3
secondary. CloudStack does not support heterogeneous secondary storages in a Region.

There is a limitation of our support for using S3 as Region-wide secondary storage. In a cloud,
if you add S3 as a secondary storage, you cannot have other zone-wide secondary storage existing;
For example, if you have an NFS secondary storage, you cannot add a S3 as secondary storage.
If you want to use S3 as secondary storage, then you can add your NFS as S3 staging store
only.

Details are
This is documented in the design doc published on ACS https://cwiki.apache.org/confluence/display/CLOUDSTACK/Storage+Backup+Object+Store+Plugin+Framework,
maybe release notes didn't state that clearly. In 4.3, we will support migration NFS to S3
by automatically converting existing NFS secondary storage to S3 staging stores. See https://cwiki.apache.org/confluence/display/CLOUDSTACK/Migration+of+NFS+Secondary+Storage+to+Object+Store
for details.
