Dear Lars, Thanks a lot for the detailed response, let me see what I can do in terms of partitions. Generally the task I am trying to solve is the following: - there is a 100-gigabyte collection of large files (10 mb to 1 gb) - there are several geographically distributed sites with people that need access - files are organized in folders, and there is a fairly good administrative separation on who needs which files - i.e. chances of people writing the same file at once are pretty low - speed is important as well as a way to access any file from anywhere (but ok to degrade speed if replicas aren't synced yet)
So the question is - do you think OpenAFS is a right tool for this problem?

As the protocol is compatible with rather old versions, you can mix client and server versions. BUT as security and bandwidth wise you should use a 1.4.12 or newer server on your *nix machines. For a client use 1.5.74 on windows and 1.4.12 on *nix machines. If you want to test and feel lucky, try the dev builds of 1.5.x on *nix and report bugs/errors/... > 2. tried to compile and it worked but it created a non-"mp" kernel module > while my kernel needs an mp one - how to fix that? > 3. do I really need a new fresh partition to start with or I can re-use an > existing one and just make it available via afs? > Actually #3 is the most important so let me explain.

OpenAFS does have its onw structure of files in the server-partitions (but it is not influenced by "false" files in those partitions). Which ends up in: you need to copy your files into the OpenAFS space after you have created the server and volumes and the logic fs-tree structure. You COULD share the openAFS fileserver-partitions via NFS or else and save extra data in those partitions (which are left alone by the OpenAFS fileserver) but that includes horrible security issues and is absolute NOT a way to go. More important about a new setup are some limits,IMHO the most important for new users are: - -only 1 ReadWrite copy of a volume - -no more than 64k files in a directory - -replica only on manual/script interaction - -only whole file locking on server - -experimental disconnected-mode But those are all fields which are worked on. > Thanks a lot for the information in advance, > Mike Pliskin MfG, Lars Schimmer - -- - ------------------------------------------------------------- TU Graz, Institut für ComputerGraphik & WissensVisualisierung Tel: +43 316 873-5405 E-Mail: [email protected] Fax: +43 316 873-5402 PGP-Key-ID: 0x4A9B1723 -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iEYEARECAAYFAkvas9UACgkQmWhuE0qbFyOeoQCfU3I895CFV8BpjpbeOCNLLFKJ E9QAn2tbqhiBWX+wf5d6OnxsN4AZ0NsO =v20Z -----END PGP SIGNATURE----- _______________________________________________ OpenAFS-info mailing list [email protected] https://lists.openafs.org/mailman/listinfo/openafs-info :�� T���&j)b� b�өzpJ)ߢ�^��좸!��l��b��(���~�+����Y���b�ا~�����~ȧ~
