Announcing the Availability of the
|
|
Coda Distributed
|
|
Filesystem
|
|
for
|
|
BSD Unix Systems
|
|
|
|
Coda is a distributed filesystem like NFS and AFS. It is
|
|
freely available, like NFS. But it functions much like AFS in being a
|
|
"stateful" filesystem. Coda and AFS cache files on your local
|
|
machine to improve performance. But Coda goes a step further than AFS
|
|
by letting you access the cached files when there is no available
|
|
network, viz. disconnected laptops and network outages. In Coda, both
|
|
the client and server are outside the kernel which makes them easier
|
|
to experiment with.
|
|
|
|
To get more information on Coda, I would like to refer people to
|
|
http://www.coda.cs.cmu.edu
|
|
There is a wealth of documents, papers, and theses there. There is
|
|
also a good introduction to the Coda File System in
|
|
http://www.coda.cs.cmu.edu/ljpaper/lj.html
|
|
|
|
Coda was originally developed as an academic prototype/testbed. It is
|
|
being polished and rewritten where necessary. Coda is a work in
|
|
progress and does have bugs. It is, though, very usable. Our
|
|
interest is in making Coda available to as many people as possible and
|
|
to have Coda evolve and flourish.
|
|
|
|
The bulk of the Coda filesystem code supports the Coda client
|
|
program, the Coda server program and the utilities needed by both.
|
|
All these programs are unix programs and can run equally well on any
|
|
Unix platform. Our main development thrust is improving these
|
|
programs. There is a small part of Coda that deals with the kernel to
|
|
filesystem interface. This code is OS specific (but should not be
|
|
platform specific).
|
|
|
|
Coda is currently available for several OS's and platforms:
|
|
Freebsd-2.2.5: i386
|
|
Freebsd-2.2.6: i386
|
|
Freebsd -current: i386
|
|
linux 2.0: i386 & sparc
|
|
linux 2.1: i386 & sparc
|
|
NetBSD 1.3: i386
|
|
NetBSD -current: i386
|
|
The relevant sources, binaries, and docs can be found in
|
|
ftp://ftp.coda.cs.cmu.edu/pub/coda/
|
|
|
|
We intend to come out with new Coda releases often, not daily. We
|
|
don't want to slight any OS/platform not mentioned above. We are just
|
|
limited in our resources as to what we can support internally. We
|
|
will be happy to integrate OpenBSD support as well as other OS
|
|
support. Also, adding platform support should be relatively easy and
|
|
we can discuss this. The only difficulty is that Coda has a light weight
|
|
process package. It does some manipulations in assembler which would
|
|
have to be redone for a different platform.
|
|
|
|
There are several mailing lists @coda.cs.cmu.edu that discuss coda:
|
|
coda-announce and linux-coda. We are going to revise linux-coda to be
|
|
OS neutral, since it is mainly Coda we want to discuss. We appreciate
|
|
comments, feedback, bug reports, bug fixes, enhancements, etc.
