Buyer Beware: A Major Change in NFS is about to happen
by Steve Dickson
Hello,
As part of the https://fedoraproject.org/wiki/Features/NFSv4Default feature
I am one commit away from changing the default protocol version NFS will
be using (or at least trying to use).
What does this means to you? Hopefully nothing! In theory this should
be a very seamless transition but with all new technology there
will be (and are) some rough spots.
Why are make the change? See the NFSv4Default wiki for details,
but in a nutshell:
* Better performance - V4 is now a stateful protocol. Meaning the server keeps
state on all the clients access a particular file or directory. This
allows the server to give out delegations (or leases) which in turn
allows the client to aggressive cache both data and meta data locally
* Firewall Friendly- With v4 only one port is used 2049 for all traffic
including mounting and file locking.
* Finally it enables us use upcoming minor releases of the the protocol.
NFS version 4.1 and pNFS are two example of upcoming minor releases.
FYI, V4 was introduced in Fedora Core 2 so it has been around for a while. I
personally have been using it for my home directory for a couple years now..
For more of the nitty gritty details see
http://www.iaps.com/NFSv4-new-features.html
That's the good news... Here is the bad....
Because the mount command will try NFS v4 first, mounts to older Linux servers
will start failing like:
# mount linux-server:/export /mnt
mount.nfs: mounting linux-server:/export failed, reason given by server:
No such file or directory
This is due to a defect in the Linux server exporting code, which is fixed
in F-12, *but* there are a number of workarounds
On the server (Which is suggested):
* Add the following entry to the /etc/exports file:
/ *(ro,fsid=0) Note: 'fsid=0' is explained in the exports(5) man pages.
On the client, go back to v3 mounts by doing one of the following:
* Add -o v3 to command line, similar to:
mount linux-server:/export /mnt
* Change the default mount version in the new /etc/nfsmount.conf file by
uncommenting the Nfsvers=3 setting in the 'NFSMount_Global_Options' section.
See nfsmount.conf(5) man page for details. The diff would look like:
--- /etc/nfsmount.conf 2009-09-29 16:58:13.000000000 -0400
+++ /tmp/nfsmount.conf 2009-09-29 16:56:04.000000000 -0400

FUDCon Toronto 2009 update!
by Paul W. Frields
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
Howdy Fedora friends and neighbors,
Here's an update on the upcoming FUDCon in Toronto, being held
December 5-7. Before the details, I want to give some special thanks
and recognition to Chris Tyler of Seneca College in Toronto for his
continued, invaluable assistance in setting up FUDCon. His help made
it possible to establish a lot of these logistics while we were also
preparing for Fedora presence at the Red Hat Summit last week. Thanks
Chris!
You'll find a lot of the details up at the FUDCon wiki page here:
https://fedoraproject.org/wiki/FUDCon:Toronto_2009
FUDCon is free and open to *everyone* to attend. The wiki page is
chock full of details, but if you'd rather see the highlights now,
just read on...
* * *
HELP US PLAN!
- -------------
In the spirit of transparency and openness, we're trying to make the
planning process of FUDCon as easy to participate in as possible. Edit
the wiki pages and let us know what you would like to see, join the
discussion list at
https://admin.fedoraproject.org/mailman/listinfo/fudcon-planning, and
join us every Thursday at 2000 UTC (4:00pm US Eastern) in IRC Freenode
at #fudcon-planning for FUDCon planning meetings.
GENERAL SCHEDULE
- ----------------
We are holding FUDCon from Saturday through Monday, December 5-7. The
first day, Saturday, will be the day of technical sessions. The
second and third days will be hackfest days where people can gather to
work on some of the projects they've seen on Saturday, or anything
near and dear to their heart.
We'll maintain a wiki listing of everything going on, updated
throughout the event to provide timely information on what's happening
where, when, and with whom. At any time you'll be able to visit the
page at https://fedoraproject.org/wiki/FUDCon:Toronto_2009 to see all
the details.
PRE-REGISTRATION
- ----------------
Pre-registration is now open on the main FUDCon wiki page:
https://fedoraproject.org/wiki/FUDCon:Toronto_2009#Pre-registration
Remember that although you're not required to pre-register, when you
do pre-register for the event you're eligible to receive a special
gift at the sign-in desk at FUDCon. There will probably be a limit to
the number of people we can pre-register, so sign up today!
But don't worry -- if you miss pre-registration, remember that FUDCon
as always is *free and open* for anyone to attend. We are happy to
have anyone attend, learn, participate, and contribute.
LODGING
- -------
We've secured rooms at the very comfortable Hilton Garden Inn
Toronto/Vaughan, with a single/double occupancy rate of CDN $105/night
(currently about USD $98). We've also secured discount vouchers for
the daily breakfast buffet to further help contain attendees' costs.
Visit this pre-set URL to register at the hotel:
http://bit.ly/fudcon-hgi-toronto-2009
** NOTE: Our name is misspelled as "FEDCon" at the registration
page, a simple snafu with the hotel. We're working on getting it
fixed ASAP!
You don't have to wait for FUDCon pre-registration to register at the
hotel. If you are looking to room-share and don't have a roommate,
you'll be able to mark that on the pre-registration and we'll do an
assignment for you.
TECHNICAL SESSIONS
- ------------------
Not all of the technical sessions will be in the BarCamp format at
FUDCon this year. That's a change from previous formats. Some will
be pre-selected so that we can make sure to cover a wide variety of
audience interests, since we frequently have more talks proposed than
available space.
*NOW* is the time to start adding content! Go to this URL and add your
talk now:
https://fedoraproject.org/wiki/FUDCon:Toronto_2009#Technical_sessions
FUDPUB
- ------
Ah, the world-(in)famous FUDPub! We are reserving a large party space
at Dave & Busters (http://daveandbusters.com) which happens to be
walking distance from the hotel. Yes, even in December in Toronto!
We'll gather there for billiards, snooker, general merriment, and of
course access to their midway full of entertainment. We'll provide
dinner and non-alcoholic beverages for pre-registrants. The venue
also has a wide variety of additional libations available for those so
inclined.
Ah, but don't party *too* hard, because starting the next day we'll
have...
HACKFESTS
- ---------
As always, we will feature plenty of hacking -- design work, coding,
documentation, general brainstorming, planning -- going on throughout
the hackfest days Sunday and Monday. If you hear about something you
like on the technical session day, chances are you'll be able to sit
down with people on Sunday and Monday, learn more, and hack on it!
If you're presenting a technical session, give some serious
consideration to how you can make your subject matter hackable. Then
invite people to get together with you the next day to work on it!
You can start by adding information about your hackfest in advance.
Visit this URL and add what you'll be working on:
https://fedoraproject.org/wiki/FUDCon:Toronto_2009#Hackfests
More information will be forthcoming as it develops!
