Hi folks,

i have problem in setting up a NFS4 server to share some locations.

i followed this document - section around non-secure connections:
https://help.ubuntu.com/community/SettingUpNFSHowTo

and my /etc/default/nfs-kernel-server now looks like this.
Code: 
# Number of servers to start up
RPCNFSDCOUNT=4

# Runtime priority of server (see nice(1))
RPCNFSDPRIORITY=0

# Options for rpc.mountd.
# If you have a port-based firewall, you might want to set up
# a fixed port here using the --port option. For more information, 
# see rpc.mountd(8) or http://wiki.debian.org/?SecuringNFS
RPCMOUNTDOPTS=

# Do you want to start the svcgssd daemon? It is only required for Kerberos
# exports. Valid alternatives are "yes" and "no"; the default is "no".
#    NEED_SVCGSSD=
NEED_SVCGSSD=no # no is default

# Options for rpc.svcgssd.
RPCSVCGSSDOPTS=
as per instruction my /etc/default/nfs-common :
Code: 
# If you do not set values for the NEED_ options, they will be attempted
# autodetected; this should be sufficient for most people. Valid alternatives
# for the NEED_ options are "yes" and "no".

# Do you want to start the statd daemon? It is not needed for NFSv4.
NEED_STATD=

# Options for rpc.statd.
#   Should rpc.statd listen on a specific port? This is especially useful
#   when you have a port-based firewall. To use a fixed port, set this
#   this variable to a statd argument like: "--port 4000 --outgoing-port 4001".
#   For more information, see rpc.statd(8) or http://wiki.debian.org/?SecuringNFS
STATDOPTS=

# Do you want to start the idmapd daemon? It is only needed for NFSv4.
#    NEED_IDMAPD=
NEED_IDMAPD=yes

# Do you want to start the gssd daemon? It is required for Kerberos mounts.
#    NEED_GSSD=
NEED_GSSD=no # no is default
after restarting the NFS4 server
/etc/init.d/nfs-kernel-server restart


my /etc/exports file:

Code: 
/opt/nfs_exports  192.168.1.0/24(ro,sync,insecure,root_squash,no_subtree_check,fsid=0,anonuid=65534,anongid=65534)
/opt/nfs_exports/pveVM01 192.168.1.0/24(rw,nohide,sync,insecure,root_squash,no_subtree_check,anonuid=65534,anongid=65534)
/opt/nfs_exports/pveISO01 192.168.1.0/24(rw,nohide,sync,insecure,root_squash,no_subtree_check,anonuid=65534,anongid=65534)
since my server has two IP:
192.168.1.251
192.168.1.254

it is a Debian x64 5.0.5 installation.



i believe the IP range specified on the /etc/exports above will be correct.


however, when i try mounting any of these share i get an error message, please note that i am trying to mount it on the localhost using its IP:

Code: 
mount -t nfs4 192.168.1.254:/opt/nfs_exports/pveISO01 mnt/
mount.nfs4:  mounting 192.168.1.254:/opt/nfs_exports/pveISO01 failed, reason given by server:
No such file or directory
could anyone point me to a solution for this?


many thanks

Nicolas

I don't know the solution, but mounting NFS on localhost turned out to be quite unstable here.
Click to expand...

that actually was one of the best answers to this question so far.

i tried mounting the shares but failed with some strange results.

i tried mount shareA when in fact i mounted shareB..

no idea how.

many thanks

i will use LVM as storage instead.
