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.
