I agree with John. It's fine as implemented it just wasn't stated clearly in the documentation (or the error message) and it appears we have a migration path in place for 4.3 when wanting to convert from NFS to S3.
-Aaron (+ @dev) Min, I don't think that the current implementation is a limitation or problem. Region-wide storage will impose certain constraints on secondary storage in contained zones to satisfy data consistency and reliability requirements. Therefore, it seems completely logically that region wide secondary storage would prevent the contained zones from defining a potentially conflicting secondary storage configuration.

Ahhh – I thought you could only have one type of object storage (swift or S3) but you are saying we can only have one kind of secondary no matter the type, correct? Does this apply at the zone level or at the region level? We currently have one region, could I create another zone in that region and put S3 as secondary in the new region and retain my NFS in the existing region? In the end could we have one region with two zones (one with NFS secondary and one with S3 secondary)? Thank you!!!

Hi Aaron, This is the current 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, in your case, you already have a NFS secondary storage there, so we will prevent you from adding a S3 as secondary storage. If you want to use S3 as secondary storage, then you can add your NFS as S3 staging store.

Edison and Min – We have Citrix Summit coming up next week and we are trying to add Amazon S3 backed secondary storage to Tim Mackey's lab (copied). I reached out to John and he helped me understand some things but I'm at a stopping point and he suggested you might be able to help out. We have an NFS share on a NetApp array (/vol/exports/temp) that I can add as secondary storage with an NFS type. When I try to add the same scratch area and put in all my S3 credentials I get the following error: You can only add new image stores from the same provider NFS already added. I don't understand that error and I'm not sure how to proceed. It pops up even if I add bogus NFS paths. We're on a pretty tight time line and we hoping you might be able to lend a hand. I'm also going to post to the CloudStack User list (this is CCP 4.2 though) and see what happens over there. Thank you!
