I can help documenting the whole lot, but starting with repli-sync and 
repli-update is a good idea, as I'll have to use them soon also, and 
have recently put an eye on them.
Sadly, I'm not someone who makes things by itself, I always need a reason.
The maintainers are good-willing, off course, but have other things to 
do right now, as I understood.

We should contact each other and discuss (on IRC) about the code (I know 
it enough to reply to common questions).

I have *very* less perl knowledge but good programming experience in
some other languages. I like to help.

At first I feel, that there is less concept or less (detailed)
dokumentation. (What are the function of the different skripts of
replicator).

First I think it is important to fully understand the function of
repli-update.

What do you think about writing some dokumentation, as preparation for
programming an fixing error? Are one of the Maintainers willing to to
help on this, answer questions ?

What do you think the next step should be?

[Replicator-users] How to use "repli-sync"

[Bernd H. <bj...@da...>]

Hello,

I have replicated two hosts (frodo, giga) from one modell-most (bilbo)
using the cvs version from replicator. Now I have made some changes to
the modell and want to synchronice the replicated hosts.

This mail describes how I try to get repli-sync working. At the end
there are some new files an the model (bilbo) missing on the replicat
(frodo).

It would be nice if you can give me a hint, how I get the hosts
completly synchronizes with repli-sync. If you need some additional
information or if I can do some tests I like to do it.

Thanke
Bernd

----------------- 8< -----------------------------------------

On "frodo" I have the following repli-sync.conf:

frodo:~# cat /etc/replicator/repli-sync.conf=20
$model =3D "bilbo";
$nousr =3D 0;
$noboot =3D 1;
$norcd =3D 1;

#do not remove the following line..
$the_end=3D1;


If I try to start repli-sync I get the following error:
frodo:~# /usr/share/replicator/repli-sync=20
Name "main::share_dir_on_server" used only once: possible typo at /usr/shar=
e/replicator/repli-sync line 41.
Can't exec "/repli-update": No such file or directory at /usr/share/replica=
tor/repli-sync line 41.


The I try to set the variable $share_dir_on_server in repli-sync.conf
on frodo to /usr/share/replicator, where i have found repli-update:

frodo:~# cat /etc/replicator/repli-sync.conf=20
$share_dir_on_server =3D "/usr/share/replicator";
$model =3D "bilbo";
$nousr =3D 0;
$noboot =3D 1;
$norcd =3D 1;

#do not remove the following line..
$the_end=3D1;

frodo:~# /usr/share/replicator/repli-sync=20
Name "main::share_dir_on_server" used only once: possible typo at /usr/shar=
e/replicator/repli-sync line 41.
dpkg: warning, architecture `i386-none' not in remapping table
Erreur: no file /etc/replicator/replicator.conf available
; at /usr/share/replicator/repli-common line 70.
Compilation failed in require at /usr/share/replicator/repli-update line 45.


It seems that repli-update wants am /etc/replicator/replicator.conf.
But this file is on the modell (bilbo) and was not copied to frodo
during initial replication.

Now I copy the /etc/replicator/replicator.conf from bilbo to frodo.
Next try I got:

frodo:/etc/replicator# /usr/share/replicator/repli-sync=20
Name "main::share_dir_on_server" used only once: possible typo at /usr/shar=
e/replicator/repli-sync line 41.
dpkg: warning, architecture `i386-none' not in remapping table
Can't locate /etc/replicator/update_rules at /usr/share/replicator/repli-up=
date line 56.

Ok. I also copy /etc/replicator/update_rules form bilbo to frodo.
After that, repli-sync seems to work, may file names are scrolling over
the window. But not all new files seems to be copied:

bilbo:/home/bernd# whereis lyx
lyx: /usr/bin/lyx /usr/share/lyx /usr/share/man/man1/lyx.1.gz

frodo:/etc/replicator# whereis lyx
lyx:

[Replicator-users] Solved! Re: rsync failed in repli-install netcopy --real

[Bernd H. <Ber...@On...>]

Hello,

the Problem with rsync was related to the problem with the missing
modules.dep, I reported in=20
https://sourceforge.net/tracker/index.php?func=3Ddetail&aid=3D598742&group_=
id=3D11570&atid=3D111570

Because of the high amount of the error messages about the missing
modules.dep, I did not see the message "Can't locate module net-pf-1"

I think there a two ways to solve both problems:

a) Provide Modules
   On the miniroot-server
   1) Prepare replicator.conf
   2) Copy the Kernel-Image to the Pfad specified in replicator.conf
   3) Run repli-miniroot
   4) Copy the Modules from the used Kernel to
      <miniroot>/lib/modules/<kernelversion>/
  =20
   After booting the target with the replicator-bootdisk a new
   modules.dep is generated and rsync is working.
   This is working for me with the DHCP Kernel from the Debian-Package
   "fai-kernels"
  =20
b) Don't use modules at all
   Use a kernel witch has completly disabled modules support.
   I think such a kernel should be compiled with "CONFIG_UNIX=3Dy" to
   solve the problem about the missing module "net-pf-1"
   I did not test this.
  =20

Bernd

[Replicator-users] rsync failed in repli-install netcopy --real

[Bernd H. <Ber...@On...>]

Hello,

during trying to replicate a Debian 3.0r0 Host with the CVS-Version of
your replicator from 20.08.2002 and rsync 2.5.5-0.1 I get a strange
error with rsync.

On the miniroot-server "bilbo" is a running nfs-kernel-server and a running
rsync-Daemon. The rsync-Module "[replicator]" points to the
miniroot-Directory. No Problems with NFS.

After running:
repli-install hdsetup --real
repli-install hostconf --real
witch finish sucessfully (after adding -text2 to the mount command) ist
run:

repli-install netcopy --real

an get the following error message:

 Receive file list (or equal)
 ...
 pipe failed in do_recv
 rsync error: error in socket IO (Code 10) at main.c (377)
 ERROR: command failed!!! at main, /usr/sbin/repli-update, 192:
 rsync --archive --hard-links --sparse --whole-file -v bilbo::replicator/bo=
ot target/boot/. 2>&1


I get the same error starting rsync on the command line of target. I
tried the command "rsync -r -v bilbo::/replicator/boot target/boot/."
with the same result.

An rsync-Daemon is running on bilbo. The rsync-request is logged in
syslog of bilbo and the file list is received by targed.

This seems to be more an error in rsync then in replicator, or?=20
Can you reproduce this behavior?
Do you have any hints for me?
Witch Version of rsync do you use?

Thanks,
Bernd
