> 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.
