I'm thinking in terms of using 'File::Find' to build up a list, but this seems ... well, a bit inefficient to me - traversing a whole directory structure, in order to feed a virus scanner a list that'll... then traverse the file structure again. Can anyone offer better suggestions for how to 'divide up' an NFS filesystems, without doing a full directory tree traversal?
Doesn't your virus scanner have a 'scan this file only' option?
Beyond that, I'd look to giving the scanner one drive at a time, rather than (bits of) one file system. Drives are a small number of finite sizes so would make the capacity planning for your distributed system fairly simple.
A realise that *nix file systems are logically single entities, but it is surely possible to mount individual drives/raid units such that it appears as a single subdirectory within the file system.
