OK; how about the following.--b.

1. upstream status/merge plans (trond, bfields)

2. State of pNFS tree (bhalevy)

3. Client
	3.1. Client pNFS status
	3.2. Client state management design documentation (trond)

4. Server
	4.1. Todo's for minimal 4.1 server (bfields)
	4.2. pnfs
		pnfs/gfs2
		exofs

5. boston bakeathon

6. new business

7. next meeting

--b.

Re: Linux pNFS status meeting 07/08

[J. Bruce Fields]

Also I'd like to hand off running and taking notes on this meeting to
someone else for a while.  (Benny, maybe?)  Or we can go back to making
the meeting more informal if that's preferred.

--b.

1. upstream status/merge plans (trond, bfields)
	- upstream at 2.6.35-rc4.
	- server side: some bugfixes merged to callback code; allocation
	  failures changed to return DELAY.
	- discussion of error return on client callback-parsing error.
	- trond: everything from before bakeathon is in nfs-2.6.36
	  branch or upstream.  Also some file locking bugfixes
	  (bugzilla.kernel.org #14501).  Also sending release_lockowner
	  more often to keep server resources down.

2. State of pNFS tree (bhalevy)
	- working on patches from boaz and andy for release branch.
	  Anyone else have big pending patchsets?
		- Jim is getting complex-volume block patches tested,
		  will send them out soon.
		- Fred has some pending stuff ("minor cleanup")
	- next week would like to start cleaning up and squashing
	  together patches.  Also will truncate some of the history.

3. Client
	3.1. Client pNFS status
		- Andy needs to look at state reclaim stuff?
		- Andy still wondering what to do with the nfs inode
		  layout pointer.  What's the lifetime of the thing that
		  points to?
	3.2. Client state management design documentation (trond)
		- Also, on docs: Andy will check that wiki docs are
		  uptodate.  And will do some more documentation of
		  refcnts, as will Fred.

4. Server
	4.1. Todo's for minimal 4.1 server (bfields)
		- still working on callback changes.  Trond notes
		  ongoing rpc code improvements may allow us to do much
		  of this by keeping a single client and modifying its
		  transports, in which case I may be able to replace my
		  callbacks with single rpc tasks.
		- also fixing 4.0/4.1 bug that prevents exclusive locks
		  on upgraded open.
	4.2. pnfs
		- pnfs/gfs2
			- I'll ask Eric for a report on gfs2 bakeathon
			  testing.
		- exofs
			- I'll ask Brian about citi exofs setup status.

5. boston bakeathon
	- October 4-8.
	- Details are finalized, to be posted soon.
	- If your company will be bringing large equipment, let Sorin
	  know.
	- If anyone would be interested in sponsoring a reception or
	  other addition to the bakeathon, contact Sorin.  (Or if you
	  know who at your company would handle such a thing, let Sorin
	  know.)

6. new business
	- Sorin asked Trond for summary of layout-commit discussion.
	  Discussion ensued.

7. next meeting
	- next week as usual.

[Trond Myklebust]

Hi Sorin,

I'm getting a 'There are no rooms available for the dates you specified'
reply when I try to book for the dates 10/4 to 10/8 using the link you
provided on the web page below. Should I be using a special booking
code?

Cheers
  Trond
