 Thanks a lot! These kernels worked very well. I think I will
 stick with them.
 
 Another question: I don't really understand the difference between
 vserver-debiantools - Tools to manage debian virtual servers and
 util-vserver - tools for Virtual private servers and context
 switching.

the vserver-debiantools should not be needed on debian
as util-vserver should be able to provide all the 
funtionality ... 

for some time (maybe still? and at least in sarge) the
tools are broken, so better get them as source tarball
or from unstable/testing ...

HTH,
Herbert

 Is it safe to install both on Debian Sarge?

RE: [Vserver] unmount nfs with vserver

2005-10-18 Thread smagnuson

I have done the following but am getting a error
sudo vi /usr/local/etc/vservers/caloratst01/bcapabilities
VXC_SECURE_MOUNT
VXC_SECURE_REMOUNT
VXC_BINARY_MOUNT

I also tried:
SECURE_MOUNT
SECURE_REMOUNT
BINARY_MOUNT

I am getting the following error on vserver startup
sudo vserver caloratst01 start
Unknown bcap 'VXC_SECURE_MOUNT'

An error occured while executing the vserver startup sequence; when
there are no other messages, it is very likely that the init-script
(/sbin/init) failed.

Common causes are:
* /etc/rc.d/rc on Fedora Core 1 and RH9 fails always; the 'apt-rpm' build
  method knows how to deal with this, but on existing installations,
  appending 'true' to this file will help.

Failed to start vserver 'caloratst01'

Have I got the syntax of the file wrong?

hmm, looks like you are missing one of the

#define VXC_SECURE_MOUNT0x0001
#define VXC_SECURE_REMOUNT  0x0002
#define VXC_BINARY_MOUNT0x0004

 I thought I would be fine with it that way but it turns out it is a
 bigger issue than I thought. Any suggestions on how to umount the NFS

unmounting on the host should work quite fine ...

[Vserver] memory : free gives wrong numbers

2005-10-18 Thread Xavier Montagutelli

Hello list,

The free command gives me false number on vservers. Can someone reproduce 
the same as below :

*) Host

linux 2.6.12.4, vs 2.0
server memory : 5 Go

*) On vserver #1 :

[EMAIL PROTECTED] # free
 total   used   free   
Mem:   5128164   13738683754296
-/+ buffers/cache:   -30770728205236 --- negative number

[EMAIL PROTECTED] # ps auxw | awk '{rss+=$6} END {print rss}'
1991724

*) On vserver #2 :
[EMAIL PROTECTED] # free -g
  total   used free 
Mem:4  0   4
-/+ buffers/cache:   4091  9  --- 4To used !!

*) On the host :

[EMAIL PROTECTED] # free
total   used   free 
Mem:   5128164   4964772 163392
-/+ buffers/cache: 5124044615760

[EMAIL PROTECTED] # vps auxw | awk '$4 == vs1 {rss+=$8} END {print rss}'
1989684

So with ps on the vserver or vps on the host, vserver #1 seems to consume 
nearly 2Go of RSS. vserver-stat gives the same information.
But free gives a negative number for used memory on the vserver #1. And on 
vserver #2, memory used is ... erk ... interesting.

Do you think this is related to vserver, perhaps because of a total memory 
exceeding 4 Go (32 bits) ? Or is it a (known) limit of the free command ?

Thx

[Vserver] Quota for guest servers on /vservers, /vservers is on LVM ext3

Hi, all. After reading some of the messages regarding quota, I
would like to implement quota for the guest servers on a LVM partition
/vservers. I only care to limit the amount of space a guest
server could use and I do not care about the per user quota in each
guest.

I found this link from a recent message and wonder if the instructions applied to my situations.
http://linux-vserver.org/Standard+non-shared+quota

And how LVM could assist in limiting disk space of each guest server? (If by any means)

Please assist me in this attempt.

 http://linux-vserver.org/Standard+non-shared+quota
 

to be honest i am not sure of the above method.. all i did was create a 
logical volume using lvm for each guest the size i wanted that guest to have.  
easy to extend if more space is needed for a given guest.

i followed this how-to below but interpolated my own needs into it and it 
worked great the first time out. now each guest is limited to  a 10g 'hdd'. 
on my next round of installs some will be a 40g etc...and it doesn't place 
any extra responsibility on the kernel for quotas or anything.

http://www.gentoo.org/doc/en/lvm2.xml

although the doc is written for gentoo, the information in it is not gentoo 
specific besides how to install packages. the only other change i made was i 
did not use modules but included all lvm items needed within the kernel since 
i use monolithic kernels (not capable of loading modules). i used one volume 
which was half the raid disk system i have set aside for this, leaving the 
other half to be used sometime in the future as needed. i then used the file 
system i wanted for each guest on each virtual volume.

i made a small /vservers home mount point and then mounted the individual 
guest disks within that so it is all well separated from the host.  the final 
tree looks like this now with each volume/mount point the name of the guest:


/dev/sda6 9.4G  516M  8.9G   6% /vservers
/dev/mapper/vg-colossus  10G  429M  9.6G   5% /vservers/colossus
/dev/mapper/vg-nagios  10G  371M  9.7G   4% /vservers/nagios
/dev/mapper/vg-ns  10G  352M  9.7G   4% /vservers/ns
/dev/mapper/vg-ns110G  342M  9.7G   4% /vservers/ns1
/dev/mapper/vg-ns210G  337M  9.7G   4% /vservers/ns2
/dev/mapper/vg-prometheus10G  703M  9.4G   7% /vservers/prometheus
/dev/mapper/vg-usage10G  528M  9.5G   6% /vservers/usage

that's about as close to physically partitioning the disk for each as you can 
get but any of them are easily extendable and won't pass its own boundaries 
if a rogue guest gets artistic and desides to write pretty 1 and 0 designs 
all over the 'disk'. :) .

this was my first attempt with lvm and i honestly now cannot say how i lived 
without it before. :)

 And how LVM could assist in limiting disk space of each guest server? (If by
 any means)
 
 Please assist me in this attempt.
 Thanks.

[Vserver] I would like to know how to build a FC4 template

Hi, all. It is a good idea to build a guest server with basic all
around apps and then clone this basic server to other guest of the same
distribution, in my case FC4. Then for each clone, I would be able to
add specific apps to it.

For this matter, I could not find enough information to try. It
seems like for Gentoo distribution
http://www.gentoo.org/doc/en/vserver-howto.xml shows that you can tar
the whole guest server and then reuse this tarball.

I also found vserver-copy and read the man page and tried this on my
configured guest server. I got the following error trying to copy my
lanweb FC4 guest server to a newtest guest server:

vserver-copy -v lanweb/ newtest
I: vserver-copy: called on abc-25 at Tue Oct 18 12:28:25 PDT 2005
newtest
E: vserver-copy: Vserver file /etc/vservers/lanweb/.conf does not exist

Coudl somebody tell me what .conf file and where/how to configure/find
it? Is it the same file with /etc/vservers/lanweb/lanweb.conf
file. Currently, I disabled/do not have this lanweb.conf file.
In the man page, it also mention about /etc/vservers/vserver.conf and with my current settings, I don't have this file either.

Could someone give me some information regarding all of these .conf files? 

Thank you in advance for all your helps.

I get the same error. I just touch an empty file 
by that name and it works. you get an error at the end indicating a issue 
with the conf file but seeing as I don't use it I have not been 
concerned.

I was under the impression that the .conf file in 
question is legacy. More experienced vserver folks should probably 
correct/confirm this.

I tried limiting a vserver memory this week-end but had no luck doing it..

I tried setting the AS and RSS files in the configuration directory, but 
it doesn't seem to work the way I wanted. It kills processes (like 
apache in my tests) which need more memory than what I allowed in the 
limits.


What I would like to do is limit the usage of RAM the vserver has. It 
seems that AS and RSS limits are the total ressources of a vserver.


I want to give a vserver 128 megabytes of RAM and 1 gig swap space. I 
don't want the OOM killer to restrict applications to ask for more than 
128 megs of RAM.


I know I can do it, since how does VPS using vservers work then?

Re: [Vserver] memory : free gives wrong numbers

 Hello list,
 
 The free command gives me false number on vservers. Can someone reproduce

 So with ps on the vserver or vps on the host, vserver #1 seems to
 consume nearly 2Go of RSS. vserver-stat gives the same information.
 But free gives a negative number for used memory on the vserver #1.
 And on vserver #2, memory used is ... erk ... interesting.

yes, interesting indeed ... will look into that asap,
but I guess I need your help on that (or a machine with
more than 4GB of memory :)

 Do you think this is related to vserver, perhaps because of a total
 memory exceeding 4 Go (32 bits) ? Or is it a (known) limit of the
 free command ?

no idea yet, but we had some reports of free showing
funny values for the buffers/caches ...
(which are hard to get right, with shared resources)

best,
Herbert

Re: [Vserver] I would like to know how to build a FC4 template

 I was under the impression that the .conf file in question is legacy.
 More experienced vserver folks should probably correct/confirm this.

yes, the entire vserver-copy is legacy stuff ...

 sudo vserver vcrux02 build -m skeleton -n vcrux02 --context 200 --hostname 
 vcrux02.corporate.net --interface xxx.xxx.xxx.xxx --netdev eth0 --netmask

if you already built the config with the above, you can 
simply do:

sudo rm -rf /vservers/vcrux02
sudo cp -va /vservers/vcrux01 /vservers/vcrux02

 Hi, all.  It is a good idea to build a guest server with basic all around 
 apps and then clone this basic server to other guest of the same 
 distribution, in my case FC4. Then for each clone, I would be able to add 
 specific apps to it.
 
 For this matter, I could not find enough information to try.  It seems like 
 for Gentoo distribution http://www.gentoo.org/doc/en/vserver-howto.xml shows 
 that you can tar the whole guest server and then reuse this tarball.
 
 I also found vserver-copy and read the man page and tried this on my 
 configured guest server. I got the following error trying to copy my lanweb 
 FC4 guest server to a newtest guest server:
 
 vserver-copy -v lanweb/ newtest
 I: vserver-copy: called on abc-25 at Tue Oct 18 12:28:25 PDT 2005
 newtest
 E: vserver-copy: Vserver file /etc/vservers/lanweb/.conf does not exist
 
 Coudl somebody tell me what .conf file and where/how to configure/find it? Is 
 it the same file with /etc/vservers/lanweb/lanweb.conf file.  Currently, I 
 disabled/do not have this lanweb.conf file.
 In the man page, it also mention about /etc/vservers/vserver.conf and with my 
 current settings, I don't have this file either.
 
 Could someone give me some information regarding all of these .conf files? 
 
 Thank you in advance for all your helps.
 Steven.

RE: [Vserver] unmount nfs with vserver

2005-10-18 Thread smagnuson


I can mount it from the host using /usr/local/etc/vservers/unixdev1/fstab but 
have not figured out how to umount (if possible)

I was able to use the bcapabilities numeric values with out getting errors on 
vserver startup.
cat /usr/local/etc/vservers/unixdev1/bcapabilities
0x0001
0x0002
0x0004

even with this I am unable to unmount the nfs filesystem when mounted from the 
host into the vserver.

when trying from inside the vserver I can not even mount the nfs filesystem
sudo mount -v -t nfs calnfs01.corporate.net:/nfs_unix_data /unix_data
mount: failed with nfs mount version 4, trying 3..
mount: permission denied
the nfs server shows
Oct 18 15:31:57 calnfs01 rpc.mountd: authenticated mount request from 
unixdev1.corporate.net:783 for /nfs_unix_data (/nfs_unix_data)
Oct 18 15:31:57 calnfs01 rpc.mountd: authenticated mount request from 
unixdev1.corporate.net:787 for /nfs_unix_data (/nfs_unix_data)


I have been working on this from several angles to no avail.  Is anyone else 
mounting nfs into a vserver?  How are you doing it?  Are you able to umount it 
afterwards?


thanks

Same you can dow with a FC4 guest (must be stopped before tar'ing ...)

The configurations for each guest ist found at /etc/vservser/vsname

Hi, all. Thanks for your answers. Thank smagnuson and
Mr. Poetzl . As Mr. Poetzl suggested by those two commands, then
we just build one guest server and then (hard) copy by: 'cp -va'
the whole guest server to the new one. Is it possible that we
bypass the user-space commands/utilities to clone a guest this way? If
so, then wonderful.
Btw, is it the best possible and portable way?

i think you may be able to create logical volumes within the one large logical 
volume :)

on mine, yeah the partition i created to put the guests is simply a volume 
group, but as far as i know, as long as the /vservers is mounted first, you 
can mount additional logical partitions within it.

 i think you may be able to create logical volumes within the one large 
logical 
 volume :)
 

the reason why i say this is lvm appears to just be an application interface 
method of the manual way of using dd to create a large file then associating 
that file via the mapper and the loopx devices then initializinig a file 
system on it and then mounting it...  using this manual approach i have 
created a master encrypted 'disk' with several  volumes inside it and 
successfully mounted each with no problem... copying the one large master 
file backs up the entire subsystem i created inside as well...so if lvm is in 
fact an application that manipulates this type of setup, then you should be 
able to create volumes within a volume.


 on mine, yeah the partition i created to put the guests is simply a volume 
 group, but as far as i know, as long as the /vservers is mounted first, you 
 can mount additional logical partitions within it.

  Steven.

[Vserver] Re: Quota for guest servers on /vservers, /vservers is on LVM ext3

Oops. I found out that I could set S_CONTEXT in /etc/vservers/lanweb.conf to set the context id. Here is my lanweb.conf
IPROOT=192.168.0.78
IPROOTMASK=255.255.255.0
IPROOTDEV=eth1
S_HOSTNAME=lanweb
S_DOMAINNAME=none

>
S_CAPS=CAP_NET_RAW
S_CONTEXT=10

Once I got lanweb started and then entered it by root. At the prompt of the host, I did

vserver lanweb status

and here is the output:
Vserver 'lanweb' is running at context '49153'
Number of processes: 3
Uptime: 00:02

I did set S_CONTEXT=10 just in case I did not set it correctly.
However, in both case, my context is not 10 and always different
numbers. Is there any restrictions on the range of context id?

Is this kind of servername.conf configuration file a legacy stuff too?
What could be wrong here? Could some expert give me some info on this?
I would like to solve this so I can have a context id for my guest server to set up quota on it.

Thanks.

[Vserver] Re: Quota for guest servers on /vservers, /vservers is on LVM ext3

Ooops. Interesting development on trying quota based on http://linux-vserver.org/Disk+Limits


Currently I have 
/dev/sys/vservers
/vservers
ext3 defaults,tagxid 0 2

Howerver, because I just reboot the host server, so I started the guest, enterred it by root. Then I went to /usr/local/src/httpd-
2.0.55 and here what I did.

[EMAIL PROTECTED] httpd-2.0.55]# more config.log
config.log: No such file or directory

As you can see, suddenly some files lost
permissions as well as owner and group owner settings and I tried to
read one of the files and there was such error.

I then stop the guest, umount /vservers and removed tagxid from the
entry on /etc/fstab. I then mounted /vservers, started server,
entered it, then everything went back to normal.

I also tried to go back to the previous errors and instead of bailing out, I did this on the host server:

vserver lanweb status
Vserver 'lanweb' is running at context '49158'
Number of processes: 3
Uptime: 00:10
[EMAIL PROTECTED] vservers]# chxid -c 49158 -R lanweb/

Then inside the guest server, everything is back to normal again.

Well, I am waiting for some experts to give me a hint on how I could set the context-id before I continue with this quota stuff.

Anyway, there are something interesting regarding this, and it would be
nice if some experts here explain this strange or well defined
behavior so I and probably others could learn a thing or two
about vserver.

Thanks in advance.
Steven.

P.S. Sorry for sending too many emails on the same topic.
