> 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.
