Rakesh Radhakrishnan commented on HDDS-6213:
--------------------------------------------

[~pifta] [~erose] Will this conditional action be executed irrespective of the "{{{}pre-finalized" state{}}} of OM. IMHO to disallow any operations on a FILE_SYSTEM_OPTIMIZED("FSO") bucket by a {{{}pre-FSO client(old version client){}}}. Only {{new client}} can create and talk to FSO bucket.

> Currently, the upgrade framework provides annotations that can be applied to RPC endpoints to fail calls when the cluster is pre-finalized for a certain layout version. Features like EC and FSO may add parameters to existing endpoints, instead of adding new endpoints, and the request only needs to be blocked or modified if certain arguments are passed in. This Jira proposes adding annotations for conditional failure based on the arguments supplied and the cluster's metadata layout version. Pluggable actions given to the annotation could fail the request or modify the arguments before proceeding.
