Thanks for the info Pierre ! 1 Question thought - we are setting up Swift as Secondary - with new zone, from scrath.
What is the proper order of steps - my understadning is as folowing: - deploy normal NFS secondary storage - wait for SSV/CPVM to be provisioned etc... - call the API required to transform Sec NFS to Staging NFS and introduce Swift. Or can we just create Staging NFS and Swift - not sure if systemVM template is going to be properly used to bring SSVM/CPVM... ? Again, thanks for sharing your experience !
