depends on your setup/permissions ... if you have
access to the host system, simply mount it there

inside, you have to use some kind of userspace nfs
daemon as you do not have/get kernel support without
proper permissions ...

HTH,

Hi

I remember having done from the root server:

chbind --ip myvserverip  --bcast myvserverbroadcast   mount -t nfs
mynfsserver:/myshare /vservers/myvserver/mnt/mymountpoint


Nowwaydays you probably have to be in the right namespace so do at
first:

vnamespace -e myvserver /bin/bash

Not tested recently. If all went well the nfs share shoud be visible
inside the vserver.

I have tried this, I can mount the nfs filesystem but it is not viewable inside 
the vserver.  Something else I need to do?

You should be able to put the mount entry in /etc/vservers/XXX/fstab,
and it will be mounted at the appropriate time on vserver startup.

The alternative is to turn on "secure mounts", whereby the vserver can
do mount operations, with certain restrictions.  I haven't needed to use
this myself.

RE: [Vserver] mount a NFS filesystem into a vserver

2005-09-14 Thread smagnuson 

Sam,
That worked like a charm.  I was thinking that is was going to be more 
complicated than that.

For anyone interested here are my steps

On NFS server (non vserver)
---
added vserver host/root system ip address to nfs shares
ie:
sudo vi /etc/exports
/nfs_unix_data vserverhost.corporate.net(rw,sync,insecure,no_root_squash)

sudo exportfs
sudo exportfs -r (to reread your config changes)
sudo exportfs


On vserver host/root system
---
start portmap
start rpc.statd

sudo vi /usr/local/etc/vservers/unixdev1/fstab
calnfs01.corporate.net:/nfs_unix_data /unix_data nfs hard,intr,nolock 0 0 

sudo vserver unixdev1 stop
sudo vserver unixdev1 start
sudo vserver unixdev1 enter
df -h
FilesystemSize  Used Avail Use% Mounted on
/dev/hdv1  58G  8.0G   47G  15% /
none   64M 0   64M   0% /tmp
calnfs01.corporate.net:/nfs_unix_data
  100G  406M  100G   1% /unix_data

I wasn't able to find any other process that worked.  The above will work fine 
for what I need.  

On a minor note: Anyone know how to umount this now that it is mounted?  I am 
ok with restarting the vserver if that is the only way.
ssh unixdev1
sudo umount /unix_data
umount: /unix_data: must be superuser to umount
umount: /unix_data: must be superuser to umount

thanks
sig
