------------------------------------- Chair(s): Spencer Shepler <Spencer.Shepler@sun.com> Brian Pawlowski <beepy@netapp.com> AGENDA: Tuesday, August 2, 2005: 14:00pm - 16:00 (2 hour) Subject to change Welcome and Introduction (beepy) 2 minAgenda bash - Blue Sheets - NOTE WELL Agenda bashed, blue sheeted and noted well. All your IP is belong to us. June Bakeathon results (Shepler) 10 min No issues found, two new participants in interoperability testing. Sun is exploring ACL model in context of new local file system. Next IETF meeting is early in November. Some discussion on best practices for setting up Active Directory for security thingies. Action Item: Next Bakeathon Active Directory and KDC testing and issue identification. Honeyman suggested we're getting to point where maybe we need only 2 Bakeathons a year. Shepler to take to mail list. Looking for a sponsor for next Bakeathon at CITI/UMich after Austin. pNFS 20 min Garth led discussion. Better support of cluster file systems? Noveck responded on mail list - maybe the issues shoul be factored out of the pNFS draft. Other issue is possible race conditions between LAYOUT_GET and other calls. Because of two connections. Likely a STATE_ID or SEQUENCE_ID? David Black said Highroad experience suggested that sequencing needed? Byte range delegations - should be done in one way. Whole idea came out of pNFS but useful outside of it. Delegation needed to safely cache layouts - coupled to byte range delegation. Pull out of pNFS and factor into NFS V4.1. Dragon in the work (David Black) caching only valid over the byte range delegation. Linux EXT3 may have issues with change time... as a way to implement consistency. The V4 protocol requires a real change attribute. Bruce Fields said there is a client checking change time in a single compoound after mod (?) and it is failing to detect change? Spencer observes we shouldn't try to fix broken file systems in protocol. (Aside from Brent Welch - is there a client flush operation? - yes, session bring down signals to server to reap all state held for that client). David Black said blocks draft is hakey jakey. Brent Welch thinks byte range delegations are good - may need stronger cache consistency metric rather than change time. Some back and forth regarding whether NFS cache consistency (strong) is sufficient for apps - thought is keep it simple and let apps do what apps do anyway. Can you give apps serialization with advisory locks - yes. Brent Welch summarized. Main ops draft looks good. Metadata issue with clustering may need address. There are a handful of issues in main ops draft. State ID on layouts... Three docs need to be smoothed out amongst themselves. Garth Goodson observed we may have to add striping and mirroring concessions to main doc. Need to take this discussion to alias. Mark Eshel raised striping and parallel READDIRPLUS. Caused people distress. Need to convert pNFS drafts to working group drafts. Work to combine SECINFO, Sessions, (Shepler) 20 min Shepler made weak and feebles. His new commitment is September 6. Collapsing individual drafts. Cleaning up. Sessions draft etc. have lots of background that needs pruning. Shepler will generate an XDR file for .1 extensions. Bruce Fields - why do all things have to go into one minor version? Maybe overhead of discussion should be amortized... Interoperability testing to be done in February likely. Shepler wants to have two independent implementations before WG last call. Is there a chance for pNFS to get into 4.1... Or should it be 4.2? We could do in parallel... We need directory delegations implementation before February. Concern in room about lack of interest? I'm confused. September 15... for WG ready and vetted pNFS - we will discuss at that time whether 4.1 or not. NFS DNS Considerations for identities and ACLS 10 min DNS config proposal. Brent Welch - isn't LDAP better? User and Group ID mapping - no, just domain I am playing in. Which domain. UID/GID name space at sun.com - regardless of sub-domains...Want a single record to present the "realm" binding for identity. NFS Referrals 10 min Carl Burnett and Dave Noveck to move forward as informational RFC explaining how to use "referrals" for migration/replication. Shepler will tell them to move forward. (Nico mentioned minor version negotiation? Shepler to see if he can get consensus.) RFC3530 I18N issues (Williams) 5 min There are none? Nico was going to try and convince people of a string profile... But he is giving up? There is no desire in related communities. SPKM alternative for NFSv4 (Williams) 5 min It will be a lot easier to specify a DTLS (?) mechanism for SPKM. Need a meeting to iron out with relevant parties on moving forward SPKM. beepy observed we might need a respin if we don't simply drop. Andy Adamson and Peter Honeyman are sympathetic to DTLS. Lots of discussion to be had... Status of NFS/RDMA (Talpey) 5 min Problem Statement is done deal. Move forward. NFS RDMA is a RPC tweak document. Direct Data Placement drafts. Mallikarjun's comments from March need merging... Talpey to be spanked. Incosistencies in text and protocol description - of sessions. Talpey to fix. By September 6. Several implementations. Problem Statement to go to last call. WG call for final comments on the September 6 drafts. WG Goals/Milestones (Shepler) 15 min Spencer Shepler... API advancement draft removed from work queue. Migration/replication is in charter - IBM is whacking on something - need to reconcile with CITI stuff. beepy to try and wrest something out of these guys. MIB work. What to do... Adamson wants to review the MIB draft...he will give to student (expired draft) to revise. Shepler to send expired draft. The testing document to advance draft. For next summer consideration because we want some more maturity in the interoperability. Move forward DNS record stuff, etc. See slides. WG last call for minor version in late spring proposed. Hufferd asked about testing of RDDP... pNFS to be moved forward with approval of area directors - beepy to drive... Garth Goodson to own driving con calls... September 15. Security considerations for DNS record... Nico raised - will have to be resolved... Need consideration - Spencer Shepler owns. Kitten chair... asked about channel bindings document... asking about channel bindings work... Shepler responded we're at point of doing implementation work - need to follow up with Mike Eisler on state of doc... Wrapup (beepy) 1 m Well done everybody... (Small asides on color blindedness and blue sheets)... |
