I'll take a quick hack at an overview, but authoritative answers will come from somebody else (probably Jan Harkes; Ivan Popov is a reliable experienced user and there are a couple others whose names I forget, mea culpa). >>>>> "Michael" == Michael James <Michael.James_at_csiro.au> writes: Michael> What are the limits of Coda? Rather complicated as compared to normal file systems, or even familiar network file systems. Coda limits come in two flavors, RVM-related and cache-related. Basically, file size and things like that are limited to the size of the client cache. File system complexity (for want of a better word) is limited by the way things are organized in RVM. All meta data (ie, the entire directory hierarchy for all volumes, and some file attributes and maybe ACLs) must fit into RVM. Also, there are some arbitrary limits like the number of files per directory. Michael> What is the biggest file it can handle? The size of the local cache, or the maximum int (unsigned int?). I don't think Coda groks large files yet. Michael> What is the biggest Coda volume? I don't think there's a limit in bytes. Michael> What other limits might bite a user with lots of big files?? The main one I would think of in your application is that you do not get online access to the file. If the file is not in the cache already, the program will block in the open call until the file is in cache. This is different from other networked file systems where you have access to any data that has already been transferred. On the other hand, you probably will never run into any of the RVM-based limits: 400GB/2GB = only 200 files.

Really there isn't much alternative for this kind of question to browsing the mailing list archives, or asking on the mailing list. -- Institute of Policy and Planning Sciences http://turnbull.sk.tsukuba.ac.jp University of Tsukuba Tennodai 1-1-1 Tsukuba 305-8573 JAPAN Ask not how you can "do" free software business; ask what your business can "do for" free software.Received on 2003-11-01 07:44:29
