so, that's how it works for me.
this is how i set it up, synthesized from
http://linux-vserver.org/alpha+util-vserver under vhashify.
* mkdir -p /etc/vservers/.defaults/apps/vunify/hash
* mkdir -p /home/vservers/.hash
* ln -s /home/vservers/.hash /etc/vservers/.defaults/apps/vunify/hash/0
* mkdir -p /etc/vservers/vserver/apps/vunify
* customize exclusions (if necessary)
o cp
-av /usr/lib/util-vserver/defaults/vunify-exclude
/etc/vservers/vserver/apps/vunify/exclude
o echo '/usr/src/*' /etc/vservers/vserver/apps/vunify/exclude
* vserver vserver hashify -nv | less
* vserver vserver hashify
all but the first three steps should be repeated for each vserver.
note: /etc/vservers/.defaults/apps/vunify/hash/0,
/etc/vservers/.defaults/vdirbase,
and correspondingly /etc/vservers/*/vdir must all be (or symlink to
directories) on the same filesystem, otherwise hardlinks cannot be
created.
hth.

Thanks for the detailed explanation. I have done exactly what you said,
but the two folders /etc/vservers/.defaults/aaps/vunify/hash/0 (and the
linked one /home/vservers/.hash)
contain a separate file for each file in the 2 vservers I unified (i.e.
twice as many files as there should be). So when I check my vserver
files, the number of links is 2 for the unified files: one link from the
vserver and one link from the host. But the files are not unified
between the two vservers.
Is there any configuration that might be necessary for unification and I
may have missed?
Thanks,

Hi there, on Tuesday, May 23, 2006 at 9:08:12 PM there was posted: AG i have issue on the unify test on debian, perhaps you have something AG related or a beecrypt issue ? FC5 from RPM work's fine out of the box yet, this is prooven binary packages. The problem _is_ somewhat related to installing yum-2.4.1 from FC4 instead of 2.6 original version supplied with FC5. I guess this can relate just to dependencies of FC4 yum only, which I don't have avail for the moment. -- regards 'n greez, Guenther Fuchs (aka muh and powerfox) ___ Vserver mailing list Vserver@list.linux-vserver.org http://list.linux-vserver.org/mailman/listinfo/vserver

2006/5/23, ADNET Ghislain [EMAIL PROTECTED]: sorry to jump on the thread, just a little test : when you make the vserver-util, do the make check worked for all tests ? i have issue on the unify test on debian, perhaps you have something related or a beecrypt issue ? You cannot use Debian-supplied beecrypt. Grab the source of 4.0 or newer from sourceforge or wherever (4.0.0 is fine, as is 4.1.2, tested on these two versions). It should be in the archives btw, because I remember writing about this earlier. i presume you are referring to the beecrypt released with sarge. if anybody is using the util-vserver (and necessary beecrypt) from sarge, they have my sympathies. on sarge i use the packages from backports.org, versions 0.30.210 and 4.1.2. instructions for using backports.org are at http://backports.org/instructions.html. to provide background to my previous post in this thread, the vhashify demonstration, i'm running debian sarge with ubuntu's linux 2.6.12 source (from breezy) patched with vserver 2.0 using util-vserver 0.30.210. corey -- [EMAIL PROTECTED] ___ Vserver mailing list Vserver@list.linux-vserver.org http://list.linux-vserver.org/mailman/listinfo/vserver

[Vserver] Quick question
Hi, I just wanted to make sure hashify only unifies rpm packages, right? Any other files I want to unify I will have to manually hardlink them? And vdu gives the disk space counting only files that have one hardlink, but when I do a vdu on my vserver directory I get 0...why is that?
