What is the behavior of the client when such an error is returned. Does it retry ? If yes, how many times and with what kind of interval between each retry ? Is the behavior similar to what the NFSv3 client when receiving NFS3ERR_JUKEBOX ? My purpose is to run NFSv4.x on top of a namespace whose entries can be migrated : opening a file may require staging it (in this case NFS4ERR_DELAY and NFS3ERR_JUKEBOX will be returned) Philippe
