Running nfs-ganesha 4.0.12 in a Debian Bookworm container, I get mount failures
mount -t nfs -o proto=tcp,vers=4 localhost:/exports /mount_nfs
mount.nfs: mounting localhost:/exports failed, reason given by server:
No such file or directory
from within the container and the host operating system when I've
exposed port 2049 for NFS v4 although I've exported the directory and
the ganesha log output reflects this.
/exports is the root of an ext4 file system
Any ideas? The failure mode is the same if I try mounting a directory
which does not exist and is not exported.
Export clause:
EXPORT {
# Export Id (mandatory, each EXPORT must have a unique Export_Id)
Export_Id = 1;
# Exported path (mandatory)
Path = "/exports";
# Pseudo Path (required for NFS v4)
Pseudo = "/exports";
# Access control options
Access_Type = NONE;
#Access_Type = RW;
Squash = No_Root_Squash;
# NFS protocol options
Transports = UDP, TCP;
Protocols = 3, 4;
SecType = sys;
Disable_ACL = false;
# changed to false, otherwise normal users can't access
directories where gid=0
Manage_Gids = false;
#to test disable getattr cache
#Attr_Expiration_Time = 0;
Anonymous_uid = 65534;
Anonymous_gid = 65534;
CLIENT {
Clients = 127.0.0.1, 10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16;
Access_Type = RW;
