Apologies, I've been busier than usual and forgot to send out my notes:
1. upstream status/merge plans (trond, bfields)
- rc7 released
- bfields: reclaim complete, benny's patches
- Trond: cleaning up branches, merged 2.6.35 stuff in (stack
reduction, Chuck's rtc-resolution patches). Haven't merged in
access & auth cache -shrinker changes. Also: state-recovery
thread deadlock still being worked. Rearranged rpc-task
structure fields to shrink struct size. That done, will send
changelog to list.
2. State of pNFS tree (bhalevy)
- [distracted, missed some notes]
- note also cleaned up gfs2 branch
3. Mailing list change
- no problems reported, except Benny getting repeatedly bounced
off? He'll investigate farther. No response from postmaster.
4. Client
4.1. Client pNFS status
- stable/unstable write-discussion.
- Andy notes: usually tests with writes to gfs2 turned
on, even though not really optimal (and will stay turned
off in mainstream).
- Benny: working on some io path bugs; will discuss on
mailing list bugs. Ricardo: note Fred may be working
on same area. (E.g.: on "done" path, two closes (one
of layout_commit context, one layout return on close
path?) were racing with each other? Looks like there
may be patches that fix that. Also saw stable
object-layout write problems.)
- Alexandros doing some work on layout-management, close
to sending.
- what about ipv6?: reports are that it's work; not sure
anyone's been thinking about it hard, though.
(What about device cache? Andy should take a look.
What about gfs2 data server references? Ricardo says
this was all "priority B" on client.)
4.2. Client state management design documentation (trond)
- some progress last week, none this.
5. Server
5.1. Todo's for minimal 4.1 server (bfields)
- Benny's patches
- pynfs testing
5.2. pnfs
- question about exports.
- exofs; did some testing, no report yet (distracted by
some bugs)
6. redhat status (steved)
- nothing to report
7. bakeathon plans
- ann arbor: going fine
- boston: still waiting on hotel details.
8. new business
- none
9. next meeting
- same time (note Benny and Boaz expect to miss it).
