Hi, friends: I'm studying the affect of NFSv4 on Linux. As far as I know, NFS implemented in Linux kernel supports read delegation but not write delegation. I wonder if Ganesha implements write delegation? If yes, can it take effect if accessed by Linux NFS client?
I use the following config file to observe delegation in Ganesha: EXPORT { Export_Id = 77; Path = /e; Pseudo = /e; Access_Type = RW; FSAL { Name = XFS; } Delegations = readwrite; } NFSV4 { Delegations = true; } However, I did not see any trace of delegation under various workloads (example: repeated read [1], repeated write [2]) using tools like nfstrace or tcpdump. When running in debug mode, I always got the following in the log file: ganesha.nfsd-8999[main] display_fsinfo :FSAL :DEBUG : delegations = 0 indicating that delegation was not on. Is there something wrong with my config file? Or any other clue regarding NFS delegation? Thanks ( ; Ganesha V2.5-rc6 running on Fedora 25, accessed by CentOS 7 client.
