Hello

I have a HN with some CTs and need to do a nfs server in one of them. I have followed the wiki, all modules/settings are made however cannot start the nfs inside the CT.

On HN I have the nfs and nfsd modules loaded.
lsmod | grep nfs
pio_nfs 19011 0
ploop 118719 14 pio_kaio,pio_nfs,pio_direct,pfmt_raw,pfmt_ploop1
nfs 445290 6 pio_nfs,vzrst,vzcpt
fscache 55676 1 nfs
nfsd 313774 1
lockd 76070 3 vzrst,nfs,nfsd
nfs_acl 2655 2 nfs,nfsd
auth_rpcgss 46084 2 nfs,nfsd
sunrpc 271776 10 pio_nfs,nfs,nfsd,lockd,nfs_acl,auth_rpcgss


When I start the nfs service inside a CT I get, but as you can see the modules already laded in the HN.

Starting NFS daemon: rpc.nfsd: Unable to access /proc/fs/nfsd errno 2 (No such file or directory).
Please try, as root, 'mount -t nfsd nfsd /proc/fs/nfsd' and then restart rpc.nfsd to correct the problem

The HN and CTs are running centos 6.7 (HN -64bit, CTs 32bit) with latest updates, with kernel Linux 2.6.32-042stab111.12.

Nor sure why the nfsd is not seen inside the CT, what should I check?

Thanks!

have you restarted your nfsd container after loaded the kernel modules in your hn for nfsd?

Yes, I have restarted several times, same message that the nfsd is not loaded. The nfs and nfds modules are set to autload at boot time for the HN - added the modprobe nfsd and modprobe nfs to /etc/rc.modules. Also, added to load in to rc.local, same issue.

vzctl version 4.9.4 is used on the HN.

Not sure why nfs4 is used, I have set MOUNTD_NFS_V3="yes" RPCNFSDARGS="-N 4" and NFSD_MODULE="noload" in /etc/sysconfig/nfs inside the CT. Why is loading the v4?

vzctl exec 104 cat /proc/filesystems
nodev cgroup
nodev devpts
nodev mqueue
ext4
nodev nfs
nodev nfs4
ext3
nodev delayfs
nodev devtmpfs
nodev sysfs
nodev proc
nodev tmpfs
nodev binfmt_misc
nodev rpc_pipefs

Installed also the testing kernel 2.6.32-042stab112.7 and despite the modules are loaded in to the HN, the nfs won't start inside the CT.
