If I'm right (I heard this nut not checked yet), NFS has hard and soft
modes. When the soft mode is turned on, every file function fail will
reported back to the application and won't try to make the job (in loop).

Yes, it's true. This solution should be for case when I can't store to
local disk (disk full/ local filesystem fail). My idea:
1. try to store to local filesystem
2. if it os OK, go next, if it FAILs, try to save to a remote FS e.g. NFS
3. if everything FAILs (little probability) accounting returns with FAIL

Unfortunately I don't have many experiences with NFS (I used it only for
centar file distribution - storage). I'm asking because there should be
more experienced users with distributed filesystems/locking/RADIUS :)
Thanks

p.s.: what is your idea, how should I solve filesystem problems - FS
fail-over? (I have also SQL databases, but I need for archivation those
CDRs)
