- Complete server export getdeviceinfo/getdevicelist implementation [Marc/Dean]
- Number of sessions slots hardcoded to be number of rpc slots. Need ability to dynamically change this value. rpc_slots is ceiling on sessions_slots. Dynamic slot allocation on client and server. [Rahul]
- Sessions priority on sessions slot table. Change to use priority wait queue for slot table. (will do fair scheduling) []
- Session/sunrpc retry behavior [?]
- Session interupt issues [?]
- Incremental sessionid creation issues [Marc]
- Client layout syncronization issues [Benny]
- 2.6.18 client port to 2.6.23 [Andy, Ricardo]
- Managing layout segment (alloc/inject layout) [Andy, Benny]
- Layout device/lease []
- Delegations and Layouts []
- Continue to use devicelist on mount? []
- MDS/DS I/O syncronization, need to determine if 'commit' needs to be sent to data servers and/or MDS []
-> Interface to layout driver is fine (sends list of dirty pages) but need flag to indicate if those pages were written to a data server or MDS (might also need another flag to say that once they are committed they also need to be layoutcommitted)
- Layoutget timing [Andy pay attention as code ported forward]
-> Put when write/read chunk size determined (nfs_pageio_init_write/read)
- Asyncronous layoutget [Future Work, Requires more investigation/justification]
- Server 4.1 replay cache [Extra 4.1 correctness work]
- Layout driver API and layout driver callback API needs to be streamlined and optimized
-> Avoid having layout driver calling NFS common code directly, it should use the layout driver callback API.
- Must call layoutcommit before removing pages from page cache.
- devicelist crashes kernel if use 4KB pages
