They are not, which causes some trouble, especially during repair sessions when the object changes from file -> symlink -> directory -> file. We do have an allocation strategy that tries to minimize how frequent these collisions occur. I believe that the Coda kernel module in 2.4 kernels tries to drop the old inode in favor of the new one in case of a collision. At some point we want to implement a collission free fid<>inode mapping in venus and will pass fids in the form 0.0.<ino_nr> down to the kernel. Such fids will hash nicely to <ino_nr>.
