    Hi Falko,

    I have a very big problem at the moment. I followed your howto Backing Up And Restoring Your Dedicated Server With SystemImager. I also have a Strato root server but as it seems Strato has decided to move from BusyBox to LFS based rescue system. And there are some components missing.

    First of all there is no /etc/init.d/ directory in this new rescue system so having a look at this post I created one for storing the functions (right?).

    But then the script stops with this error

    Code:
    get_arch
    DISKORDER=sd,cciss,ida,rd,hd
    /tmp/backup.master: line 105: logmsg: command not found
    /tmp/backup.master: line 121: logmsg: command not found
    /tmp/backup.master: line 133: logmsg: command not found
    /tmp/backup.master: line 158: logmsg: command not found
    /tmp/backup.master: line 159: logmsg: command not found

    rsync: no process killed
    
    write_variables
    \s \r \m\ \n
    LFS based rescue system
    Unfortunately your suggestion from this post could not help me because now I simply get this:

    Code:
    get_arch
    DISKORDER=sd,cciss,ida,rd,hd
    
    Disk geometry for /dev/hda: 0.000-58644.140 megabytes
    Disk label type: msdos
    Minor    Start       End     Type      Filesystem  Flags
    Killing off running processes.
    kill: usage: kill [-s sigspec | -n signum | -sigspec] [pid | job]... or kill -l [sigspec]
    udp-receiver: no process killed
    rsync: no process killed
    
    write_variables
    \s \r \m\ \n
    LFS based rescue system
    Your script is very important for me, since it seems to be the only way of restoring my test system in which I investigated a lot of time and the sollution could be interesting for many outher Strato users who like to use your script.

    I hope you can help me. Thanks in advance.

    OK, I symlinked the logger of the rescue system with logmsg, so now I have logging to /var/log/messages enabled but this didn't help me any further.

    Here my steps so far:
    Code:
    cd /tmp/
    wget http://www.falkotimme.com/howtos/dedicated_server_backup_restore_systemimager/restore
    chmod 755 restore
    ln -s /bin/logger /usr/bin/logmsg
    chmod 755 /usr/bin/logmsg
    mkdir /etc/init.d
    ./restore
    Output of /var/log/messages:

    Code:
    Jul 25 19:26:52 rescue root: enumerate_disks
    Jul 25 19:26:52 rescue root:  hda
    Jul 25 19:26:52 rescue root: DISKS=1
    Jul 25 19:26:52 rescue root: Partitioning /dev/hda...
    Jul 25 19:26:52 rescue root: Old partition table for /dev/hda:
    Jul 25 19:26:52 rescue root: parted -s -- /dev/hda mklabel msdos || shellout
    As far as I could see, the script still was't trying to restore the image and I didn't no why. It stops around here:
    Code:
    DISK_SIZE=`parted -s $DISK0 unit MB print | grep 'Disk geometry for' | sed 's/^.*-//g' | sed 's/\..*$//' | sed 's/MB//' `
    [ -z $DISK_SIZE ] && shellout
    As I had a closer look to the parted params I found out that the version of the rescue system doesn't support "unit MB" for parted. So I simply deleted it because it uses MB as standard unit.

    Now it seems to work. At lease it is running...

    More later.

    Thanks to Falko's work and his script I was able to restore my system but I'm a little bit afraid if it really worked completely as I get the following error messages at the end of the systemimager.master script. Does anybody know what that means and if it is critical?

    Code:

    ./

    Another problem is, that si_prepareclient doesn't include all installed kernel modules. I'm missing ipv6 although it's included in lsmod (see below)

    This produced some postfix errors about non supported protocols. Any ideas why it isn't included by default?

    This is the former output of lsmod on the old machine:

    mbcache                 9348  2 ext2,ext3
    So on the new machine I'm missing ipv6 although I have a line alias net-pf-10 ipv6 in /etc/modprobe.d/aliases and there is a directory /lib/modules/2.6.8-3-686/kernel/net/ipv6 with content.

    To reenable ipv6 I had to run
    Code:
    modprobe ipv6
    and to test if the module was loaded successfully
    Code:
    lsmod |grep -w 'ipv6'
    and finally to enable the automatic startup with
    Code:
    vi /etc/modules.conf
    alias net-pf-10 ipv6
    But the module is still not loaded automatically. What am I missing?

    One last thing: The ispconfig user is only shown as 110 in ps -aux. Is this correct? Shouldn't it be something like admispconfig??

    It seems like a few files are missing or truncated, e.g. /etc/modules (that's where the kernel modules are lsited that should be loaded automatically) and /etc/passwd (that's for the usernames).

    Did you restore the image onto the same hard disk, or was it maybe slightly smaller?

    It's not the same hdd since Strato has replaced the server due to a memory fault. The hardware seems to be exactely the same but perhaps the disk is a little bit bigger or smaller. Is there anything I can do now?

    If it's smaller, then you've got a problem. If it's bigger, it should be no problem.
