SystemImager Falko-Way

[pureblood]

Hey everybody, this is my first one over here, so upfront:
great site so far and man I really spent a lot of hours already trying out the most of the how tos, not that they are so fdifficult but most of all they very interesting and many of them available;-).

To the point:
I tried to figure out http://www.howtoforge.org/dedicated_server_backup_restore_systemimager
but it fails with

@ERROR: Unknown module 'scripts'
rsync error: error starting client-server protocol (code 5) at main.c(1171)
ERROR: rsync of the master script failed!


So I took a look at the script itself and found this line

rsync $image_server::scripts/$image_name.master /tmp

to be honest I have no clue what thi ":scripts" should be and why there is a ".master" behind the image variable

One would think the command should be s.t. like
"rsync -r $image_server:/var/lib/systemimager/images/$image_name /tmp"

So I guess the error is somewhere there ..

Would be amazing if some of you guys could gimme a hint ;-)
thanks in advance

Please post the output of ls -la /var/lib/systemimager on the image server.

ok this hints me to edit the ::scripts with my real directory which is /var/lib/scripts

I edited your script and now i get this

btw I also use a strato server but the rescue system does not seem to be busy box .. this maybe a problem right?

ok next thing I now just made an mkdir /etc/init.d/ so your skript can work

but next failure is this

ok this is caused because my image originated from an sda install and the server only has a hda
so I just changed the sda`s with hda`s

but now I ended up here

: bad interpreter: No such file or directory


I think this is caused by this ::${IMAGENAME}/ part in the my_image.master
and I am sure it fails for the same reason like the script failed in the first place above where I replaced
::scripts with my real directory which is /var/lib/scripts

but I dont know why this doesnt work out of the box ?
what do the two colons mean?

but now I ended up here

: bad interpreter: No such file or directory


I guess you have edited the file on Windows and then transferred it back to your server? Make sure you save the file with Unix linebreaks, not Windows linebreaks.

[pureblood]

hmm ok so i started it all over again, I did edit the files in windoze, because the f.... up vi on the rescue system didnt let me to.


but the root of all evil still seems to be the following notation
rsync $image_server::scripts/$image_name.master /tmp

could you please explain to me why there are two colons right one after another? ::

maybe this is just damn easy but I ve never encountered such a notation I am just familiar with
rsync $image_server:/scripts/$image_name.master /tmp

Is this some kind of shortened way for a path?

And man, thanks so far for your quick replies and your kind help.
It is great to have such support in ones learning process


ADDED:
I asked around a bit and looked at the rsync man pages and there I found that the

rsync HOST::SRC DEST
and that this requires a rsync daemon....

so I guess for your script to work a rsync daemon must be running?

[falko]

Yes, you must have rsync on your rescue system.

[pureblood]

I found it ;-)

on the the image server runs a xandros system and for whatever reason, the rsync manager included in systemimager-server was not startet...

now everything works fine just right out of the box without anything needed to be edited
JUST it ends with a few errors ;-(:

Is there anything I can do to fix this??
So near...

[falko]

I don't know where the df warnings come from, however, they are warnings, not errors.
Have you tested if the image works afterwards?

[pureblood]

no sorry the server didnt came online after a reboot ;-(
