Hello All. New user of openvz. I have an openvz server VE that used to be able to mount an nfs share on a remote system. VE Server lost power and nfs hasn't worked since. Have not been able to mount this nfs share. Have read and googled but can't get nfs to work. I have files on another server that I need to access from this VE and can't get the nfs share to mount. Error is:
# mount /media
mount: fs type nfs not supported by kernel
# service nfs start
Starting NFS services: OK ]
Starting NFS quotas: OK ]
Starting NFS daemon: FAILED]
Starting NFS mountd: OK ]
Starting RPC idmapd: Error: RPC MTAB does not exist.
# tail -f /var/log/messages

I've restart portmap
I've modprobe sunrpc

It was working before I lost power to the server. Any ideas?

Hi all
i have same problem. I have experience with OpenVZ but I never tried NFS with VPS. Today was first time. And i couldn't let it runing. My intention is to run NFS server in container if is possible. So I did next steps:
1) I created new VPS
2) With vzyum, installed nfs
# vzyum VPSID install nfs*
3) Setup NFS inside VPS (export, hosts.allow)
4) Inside VPS, tried to run services
# /etc/init.d/portmap
# /etc/initd./nfs
Starting NFS services: [ OK ]
Starting NFS daemon: [FAILED]
output /var/log/messages
Oct 6 11:43:38 52 nfsd[5290]: nfssvc: No such device
I read this thread and installed a NFS utils on HNode and then restarted VPS without success. When i try to run NFS on HN it happens:
Oct 6 12:21:01 hn10 mountd[31545]: Caught signal 15, un-registering and exiting.
Oct 6 12:21:01 hn10 kernel: nfsd: last server has exited
Oct 6 12:21:01 hn10 kernel: nfsd: unexporting all filesystems
Oct 6 12:21:01 hn10 kernel: NFSD: Using /var/lib/nfs/v4recovery as the NFSv4 state recovery directory
Oct 6 12:21:01 hn10 kernel: NFSD: starting 90-second grace period
IPtables on HN are disabled. And the rest of services works properly.
Kernel is:
Linux 2.6.18-92.1.1.el5.028stab057.2PAE
I checked kernel config file on /boot and nothin is returned
# cat config-2.6.18-92.1.1.el5.028stab057.2PAE |grep "CONFIG_NFDS"
Nothing returned :/
Can anybody give some idea? Do I have to recompile kernel with NFS support? or are there another way ?
Thanks!

Have you read the wiki pages on NFS?
You can't run the kernel-based NFS server inside of a container. That has been made clear from the beginning.
You can however:
1) Run a userspace NFS server (haven't tried it myself)
2) Have a container that is an NFS client
