NFSv4 problem [SOLVED]

Just upgraded to NFSv4

# pacman -Qi nfs-utils
Name           : nfs-utils
Version        : 1.2.0-3
...

# pacman -Qi kernel26
Name           : kernel26
Version        : 2.6.30-5
...

Same on both the server and client.

When I try to NFS mount from the client, I get this error:

# mount -t nfs4 vendhya:/vcpp /var/cache/pacman/pkg
mount.nfs4: No such device

I've tried manually loading the nfs4 module:

# grep nfs /proc/filesystems
nodev    nfs
nodev    nfs4
# lsmod | grep nfs
nfs                   295280  0
lockd                  72876  1 nfs
fscache                44688  1 nfs
nfs_acl                 2884  1 nfs
auth_rpcgss            38144  1 nfs
sunrpc                190560  4 nfs,lockd,nfs_acl,auth_rpcgss
# modprobe nfs4
FATAL: Module nfs4 not found.

Anyone else encountered this?

Re: NFSv4 problem [SOLVED]

Sorry, found a typo in /etc/conf.d/nfs-common.  It works now.

Re: NFSv4 problem [SOLVED]

I'm getting similar issues to this, what did you have to change in nfs-common???

Re: NFSv4 problem [SOLVED]

Hi Brenix,

I run NFS through a firewall, so I use fixed ports for statd (which I'm only using for a little while 'til everything gets moved over to NFS4).  The firewall also requires that smnotify has it's port fixed.

NEED_STATD=
STATD_OPTS="-p 12345 -o 12346"
SMNOTIFY_OPTS="-p 12344"
NEED_IDMAPD=yes
IDMAPD_OPTS=
NEED_GSSD=no
GSSD_OPTS=
PIPEFS_MOUNTPOINT=
PIPEFS_MOUNTOPTS=

(Basically, it needs to be identical to the /etc/conf.d/nfs-common.conf on your server.)

I got some issues when not specifying NFS4 as the filesystem type.  I found I had to use:

mount -t nfs4 server:/remote_mountpoint /local/mountpoint

Also, I used to disable autoload of the ipv6 module.  This seems to be required by NFS4, so you may need to modprobe ipv6 on both client and server.

Finally, I didn't need the rpc_pipefs entry mentioned in the wiki in /etc/fstab for the client or the server.

Hope this helps!
