Hi,
NFS-Ganesha version is 2.5-rc8.
The 3 servers are in the same LAN (10.0.0.0/255.255.255.0). iptables,
ip6tables and SELinux are disabled on the 3 servers. The NFS-Ganesha test
system runs on Centos 6.7 in AWS cloud (the master and the client run Amazon
Linux).
On "master" (IP 10.0.0.239), /etc/exports contains the following:
/shared/data *(rw,sync,no_root_squash)
On "client" (IP 10.0.0.145), I try to mount the directory using the
following command and I get the following error:
$> mount -t nfs4 proxy:/proxy/master/shared/data /mnt
mount.nfs4: mounting proxy:/proxy/master/shared/data failed, reason given by
server: No such file or directory
My "proxy" server (IP 10.0.0.109) is configured as follows:
- standard NFS service is stopped
- NFS Ganesha is installed using the latest git release and compiled
manually with:
$> cmake -DCMAKE_BUILD_TYPE=Maintainer -DBUILD_CONFIG=everything
-DCMAKE_INSTALL_PREFIX=/opt/nfs-ganesha/git-release ../src
$> make
$> make install
$> ./ganesha.nfsd -v
NFS-Ganesha Release = V2.5-rc8
ganesha.nfsd compiled on May 29 2017 at 22:07:22
Release comment = GANESHA file server is 64 bits compliant and supports NFS
v3,4.0,4.1 (pNFS) and 9P
Git HEAD = dfa51c44da4fffaf24164e0a64dd1d8217081788
Git Describe = V2.5-rc8-0-gdfa51c4

Objet : RE: [Nfs-ganesha-support] FSAL proxy error
What version of Ganesha are you using? How did you install it or did you
build from source?
Cc: nfs-ganesha-devel mailing list to make sure the FSAL_PROXY developers
see this and can help.

Subject: [Nfs-ganesha-support] FSAL proxy error
Hi NFS-Ganesha Support,
I'm currently setting up NFS Ganesha to use the proxying feature on a server
named "proxy". The goal is to export in NFS v4 a directory hosted on the
local storage of a server named "master" and mount it in a client server
named "client" through "proxy" .
NFS Ganesha seems to start but a CRITICAL problem is raised in the logs
about libfsalproxy_nfsv4.so:
"load_fsal :NFS STARTUP :CRIT :Could not dlopen
module:/opt/nfs-ganesha/git-release/lib64/ganesha/libfsalproxy_nfsv4.so
Error:/opt/nfs-ganesha/git-release/lib64/ganesha/libfsalproxy_nfsv4.so:
cannot open shared object file: No such file or directory"
Can you help, please?
Best regards,
Vincent
