1 1.1 rvb Announcing the Availability of the 2 1.1 rvb Coda Distributed 3 1.1 rvb Filesystem 4 1.1 rvb for 5 1.1 rvb BSD Unix Systems 6 1.1 rvb 7 1.1 rvb Coda is a distributed file system like NFS and AFS. It is 8 1.1 rvb freely available, like NFS. But it functions much like AFS in being a 9 1.1 rvb "stateful" file system. Coda and AFS cache files on your local 10 1.1 rvb machine to improve performance. But Coda goes a step further than AFS 11 1.1 rvb by letting you access the cached files when there is no available 12 1.1 rvb network, viz. disconnected laptops and network outages. In Coda, both 13 1.1 rvb the client and server are outside the kernel which makes them easier 14 1.1 rvb to experiment with. 15 1.1 rvb 16 1.1 rvb To get more information on Coda, I would like to refer people to 17 1.1 rvb http://www.coda.cs.cmu.edu 18 1.1 rvb There is a wealth of documents, papers, theses there. There is also a 19 1.1 rvb good introduction to the Coda File System in 20 1.1 rvb http://www.coda.cs.cmu.edu/ljpaper/lj.html 21 1.1 rvb 22 1.1 rvb Coda was originally developed as an academic prototype/testbed. It is 23 1.1 rvb being polished and rewritten where necessary. Coda is a work in 24 1.1 rvb progress and does have bugs. It is, though, very usable. Our 25 1.1 rvb interest is in making Coda available to as many people as possible and 26 1.1 rvb to have Coda evolve and flourish. 27 1.1 rvb 28 1.1 rvb The bulk of the Coda file system code supports the Coda client 29 1.1 rvb program, the Coda server program and the utilities needed by both. 30 1.1 rvb All these programs are unix programs and can run equally well on any 31 1.1 rvb Unix platform. Our main development thrust is improving these 32 1.1 rvb programs. There is a small part of Coda that deals with the kernel to 33 1.1 rvb file system interface. This code is OS specific (but should not be 34 1.1 rvb platform specific). 35 1.1 rvb 36 1.1 rvb Coda is currently available for several OS's and platforms: 37 1.1 rvb Freebsd-2.2.5: i386 38 1.1 rvb Freebsd-2.2.6: i386 39 1.1 rvb Freebsd -current: i386 40 1.1 rvb linux 2.0: i386 & sparc 41 1.1 rvb linux 2.1: i386 & sparc 42 1.1 rvb NetBSD 1.3: i386 43 1.1 rvb NetBSD -current: i386 44 1.1 rvb The relevant sources, binaries, and docs can be found in 45 1.1 rvb ftp://ftp.coda.cs.cmu.edu/pub/coda/ 46 1.1 rvb 47 1.1 rvb We intend to come out with new Coda releases often, not daily. We 48 1.1 rvb don't wish to slight any OS/platform not mentioned above. We are just 49 1.1 rvb limited in our resources as to what we can support internally. We 50 1.1 rvb will be happy to integrate OpenBSD support as well as other OS 51 1.1 rvb support. Also, adding platform support is relatively easy and we can 52 1.1 rvb discuss this. The only problem is that Coda has a light weight 53 1.1 rvb process package. It does some manipulations in assembler which would 54 1.1 rvb have to be redone for a different platform. 55 1.1 rvb 56 1.1 rvb There are several mailing lists @coda.cs.cmu.edu that discuss coda: 57 1.1 rvb coda-announce and linux-coda. We are going to revise linux-coda to be 58 1.1 rvb OS neutral, since it is mainly Coda we want to discuss. We appreciate 59 1.1 rvb comments, feedback, bug reports, bug fixes, enhancements, etc. 60 1.1 rvb 61
