[Vserver] mount a NFS filesystem into a vserver
I am looking to mount a NFS filesystem into a vserver. I have searched the
archives, the site, and the web but can not find a straight answer to this.
What is the proper/preferred method of doing this?
Does anyone have the steps?
I would like to mount a nfs filesystem from a non vserver (nfs server) into a
vserver (nfs client).
Thanks

depends on your setup/permissions ... if you have
access to the host system, simply mount it there
I would like to mount a nfs filesystem from a non vserver (nfs server)
into a vserver (nfs client).
inside, you have to use some kind of userspace nfs
daemon as you do not have/get kernel support without
proper permissions ...

Hi folks,
Ok, I'm totally lost. I don't seem to get a vserver install to work...
well at least not the latest version..
I am also a newbie, and I have done it with Debian recently, so let's see
what's different.
I'm trying to install vserver from this source:
http://linux-vserver.derjohn.de/ on Debian Sarge. I written down the
steps I took for this vserver installation:
[..]

[1] Wget:
http://linux-vserver.derjohn.de/kernel-image-2.6.12-p3_10.00.vserver20_i386
.deb http://linux-vserver.derjohn.de/util-vserver_0.30.208-1_i386.deb
I have used the sources from Linus 2.6.12.4 :
wget ftp://ftp.kernel.org/pub/linux/kernel/v2.6/linux-2.6.12.4.tar.bz2
wget http://www.13thfloor.at/vserver/s_rel26/v2.0/patch-2.6.12.4-vs2.0.diff

[2] Install new kernel:
~# dpkg -i kernel-image-2.6.12-p3_10.00.vserver20_i386.deb
[2a] Update /boot/grub/menu.lst to change the label so it contains vs
~# nano /boot/grub/menu.lst
[3] Reboot...
---
[4] Install Util-Vserver:
~# dpkg -i util-vserver_0.30.208-1_i386.deb
I used the sources :
wget
http://www.13thfloor.at/vserver/s_rel26/v2.0/util-vserver-0.30.208.tar.bz2
apt-get install vlan iproute e2fslibs-dev
apt-get install dietlibc-dev beecrypt2-dev
./configure --sysconfdir=/etc --localstatedir=/var
make make install make install-distribution
mkdir -p /var/lock/subsys
update-rc.d vprocunhide start 74 0 2 .
update-rc.d rebootmgr start 98 2 . stop 02 0 6 .
update-rc.d vservers-default start 98 2 . stop 02 0 6 .
[5] download and run the testscript:
~# wget http://vserver.13thfloor.at/Stuff/SCRIPT/testme.sh
[..]
[6] So, vserver 2.0 and vserver-util should be running now:
~# vserver-info
[..]
Paths:
prefix: /usr
sysconf-Directory: ${prefix}/etc
cfg-Directory: ${prefix}/etc/vservers
initrd-Directory: $(sysconfdir)/init.d
pkgstate-Directory: ${prefix}/var/run/vservers
these paths seems strange : under Debian, the sysconf-Directory should be /etc
instead of /usr/etc, cfg-Direfctory should be /etc/vservers instead
of /usr/etc/vservers, etc.
[7] Create Vserver basedir since the default location isn't there:
~# mkdir /vservers
make install-distribution makes it for you if you compile the userland
tools. Perhaps you forgot to setattr --barrier /vservers during this step ?
~# mkdir /vservers/vstest01
not necessary. The next step (vserver .. build) should do it for you.
[8] Create new Context/Virtual Server:
~# vserver vstest01 build -m debootstrap --hostname vstest01
--netdev eth0:vs01 --interface 192.168.27.33 --context 42 -- -d sarge -m
ftp://ftp.nl.debian.org/debian/
[9] /proc/sys/kernel/vshelper contains: /sbin/vshelper, must be updated:
~# echo /usr/lib/util-vserver/vshelper /proc/sys/kernel/vshelper
make install-distribution makes the link under /sbin
In your case, you could also put it in the /etc/sysctl.conf file (to make it
persistent across reboots) :
kernel.vshelper = /usr/lib/util-vserver/vshelper
[10] Then Vserver should run?
~# vserver vstest01 start
/proc/uptime can not be accessed. Usually, this is caused by
procfs-security. Please read the FAQ for more details
http://www.linux-vserver.org/index.php?page=Linux-Vserver+FAQ
That's normal (from what I have understood) : the default is that everything
is protected, you have to unlock things under /proc
I search the irc-log and then tried this:
~# /usr/lib/util-vserver/vprocunhide
Normally, this script is called by /etc/init.d/vprocunhide during the boot
process of the host system (if your Debian package configures it correctly).
The files to unhide are listed
in /usr/lib/util-vserver/defaults/vprocunhide-files (or
in /etc/vservers/.defaults/apps/vprocunhide/files if that file exists)
/proc/net/: Bad address
[.. every file to unhide with an error ..]
I have no clue what this means anyone?
I don't have any idea about that. Do you use devfs ? On my machine, there's no
devfs.
You could also try some basic commands :
cat /proc/uptime
showattr -d /proc/net
setattr --~hide /proc/net/arp

IMHO a dual GB nic and a proper switch (which is vlan aware) would be a much better solution ... but YMMV not only that but the load would be horrendous using a single nic for multiple vservers.. we are already beyond the limits of 100mbit bandwidth on the web server and the email server is pushing about 50mbit continuous at this time. our entire network is gigabit even into the border routers. and this is exactly where vlans on a GB interface would improve throughput while reducing the load if i can't do this, then my only other choice is to leave those 2 as dedicated servers which i really don't want to do. the rest of the machines have less than 10 ip addresses in each of their nics. many of these smaller servers are sharing the same net segment so packing those into the same host would allow them to share a single nic or two without trouble. everything is possible ...
