NFSv4 Implementation I−D Spencer Shepler shepler@eng.sun.com

Filehandle construction / Persistent filehandle content / Volatile filehandle content / Tradeoffs between persistent/volatile /

I18N / Further Normalization discussion / Dealing with underlying filesystems that only support single byte encodings /

stateid/clientid / Content examples / Client choices for clientid / Server choices for stateid /

State management / State needed by server and client for correct behavior / State the server can keep in non−volatile memory to enable faster recovery / State the client can keep for faster recovery /

User id mappings / Mapping techniques for user/group strings / Integration with various naming services / Potential interoperability problems with mapping techniques /

Filesystem interfaces / Local OS FS interfaces and effect on NFSv4 client and server / Potential issues for correct NFSv4 behavior / Local access to filesystem at server /

NFSv2/NFSv3 interaction / Choices for NFSv4 and how will the various servers interact / Interaction with other file server types /

Missing Attributes / Client behavior in the face of missing recommended attributes / Choices for fabricating attributes /

Migration/Replication / Server responsibilities for mig/repl / Client choices for replica choices / Client responsibilities for migration /

ACL translation / Mapping suggestions or issues /

Locking/Leases / Handling servers that don’t support
