well, yes, unification (this is vunify _and_ vhashify)
works via 'hard links', so the unified files have to
reside on the same physical partition ...

in theory yes, but it would require you to put the
guests on the same partition, which is probably not
the best idea (thinking of context tagging and such)

ahem, no, the unification is just to save disk space
and it can be done at any time (i.e. could be considered
something like 'compress your files', except that it
doesn't compress anything :) but it has nothing to do
with the software or packages installed in your guests

[Vserver] hashify and filesystem

2005-12-27 Thread Daniel Ortiz 

Hi

I am writing from Chile (sorry my english), I am newbie in the vserver wordl
and i begining to play whit this, I search the documentations and in the
mail archives but nothing can answers my questions:

 i Have a litle question about the hashify and filesystem.

First my sistem:

Debian sarge 
Linux 2.6.12.4-vs2.0 (patched)
vserver 0.30.209.

In this moment I created 2 vserves (vserver1 ans vserver2), but i want to
minimize the space in the HD, i begin to study the hashify feature, but i
cant understand some things:


1.- "In each used filesystem which contains unifyable files, create a hash
directory and link it into the database-directory"

This means that the .hash directory must be created in the vdir directory of
the vserver that have the files to unify, for example if I want to unify the
fylesistem of my vserver1:

mkdir -p /etc/vservers/.defaults/apps/vunify/hash

 
mkdir -p /vservers/vserver1/vdir/.hash 

ln -s /vservers/vserver1/vdir/.hash
/etc/vservers/.defaults/apps/vunify/hash/0 


mkdir -p /etc/vservers/vserver2/apps/vunify



vserver vserver2 hashify

2.- The host (my really machine) contains all the things that i want to
unify (apache, ssh, mysql, and another stuffs) ¿can I unify that?


3.-  and...the unify feature with hashify means that if I have some software
installed i dont need to install again in some vserver? The software in
question is fully accesible from the vserver and configurable accords the
requirements of the vserer usser? The veserver configurations of the unify
software dont are in trouble with the root or main configuration of the
software? 

Thank you in advance...sorry my english and happy new year

XFS, reiser and jfs failes because there is neither reiserfs nor jfs nor 
xfs-support in the kernel.

So far so well, i created a vserver with

| vserver chaosweb build --interface [...] -m debootstrap -- -d sarge
 which worked quite well, but i experience some errors with starting the
vserver:

| weltzentrale:~#  vserver --debug chaosweb start 
failes with:

Any ideas?

Looks like I should add that to the list.

Now that Santa Claus has gone home, I should have time to
look at three packages instead of two.

I also stumbled across the following link - which I do not
think is on the project page:

Did you look at the dropbear sshd ?

Joel, group;

I have been looking at that, it seems I have two choices:

www.matrixssl.org : : Because it is small.
www.openssl.org : : Because it is what most people expect.

If we are going to be successful at building a vserver guest
that can be remotely rescued, then the decision may have
to be made on which can be built with static linkage.

Perhaps both?  Like this:

initial-install (baby01) : : chroot/vserver rescue software
 - - - - the matrixssl staticly linked
 - - - - the BusyBox is already providing a telnetd
 - - - - the BusyBox is providing a vi editor
 - - - - the BusyBox can be staticly linked
 - - - - already have a staticly linked Bash

base-install (baby02) : : rescue, backup, restore, and maintenance.
 - - - - the openssl dynamicly linked
 - - - - a dynamicly linked nano editor
 - - - - the BusyBox is currently dynamicly linked
 - - - - I added a dynamicly linked Bash in /opt/gnu/bash/*

The baby02 level should be fine for anyone that is not playing
with an experimental libc6 (like some that I know).

People who need more features should be loading the
base-install of some Linux distribution.

I am also trying to keep this exercise within a single semester's
work in system administration - but I will not cripple the 
package for that purpose.

I will give this some more study, I can't answer my own
question at the moment.

Mike
