samba - Dec 2020 - Cloning Samba equipped VM

Hi,

I would like to smoothly clone VM running Samba.
As I understand there have to be a kind if machine ID which became duplicated in
such a case.
Are there any command to clear cloned VM data so it will advertise itself as
virgin new one?

My ideal scenario would be to:

  1.  Clone Samba to new Copy
  2.  Run, network isolated, Copy
  3.  Perform magic cleaning
  4.  Change Copy name and IP
  5.  Connect network and join AD as new VM.

What should I do in step 3?

Paku.

# Clone VM to new copy. 
1. ok, as your showed 
2. ok, as your showed
3. cleanup /var/(lib/cache)/samba/* 
   Clean/clear all logs in /var/log 
4. rgrep oldhostname /etc/* 
   Change hostnames where needed. 
5. reboot. 
   Check : hostname -f, hostname -d, hostname -s outputs. 
6. change/verify /etc/samba/smb.conf
7. join samba again. 
8. reboot
9. verify logs. 
10. get coffee your done. 


# Example clone exact as is to "move" an os from old to new hardware. 

1. install rsync on both servers. 
2. down all services on both servers execpt ssh. 
3. install a minimal OS, as minimal as possible, but the same as the old one. 
4. login in destination server.
5. run:   

rsync -auHxv ?numeric-ids ?exclude=/etc/fstab ?exclude=/etc/network/*
?exclude=/proc/* ?exclude=/tmp/* ?exclude=/sys/* ?exclude=/dev/* ?exclude=/mnt/*
?exclude=/boot/* ?exclude=/root/* root at SRC-HOST-IP:/* /

verify any udev rules for you nic. 
reboot, check logs, but should be ok now. 

Thats how i recently moved a full server from old hardware to new(er) hardware.
