Hi, I am using virtualmin pro in 2 servers and for the sake of having a backup server I frequently use module Cluster Users and Groups to add missing users and groups.
However, the quotas applied on one server are not copied on the other server so I have to change them manually.
Could you add an option to Cluster Users and Groups to replicate quotas as well? I intend to use it in a script so it would be very helpful if you could add an option to the corresponding script also, so that I could call it from command line?
Thanks in advance!

I wouldn't really recommend using Cluster Users and Groups for this kind of replication .. why not instead make use of Virtualmin's backup and restore capabilities?
You could backup all your domains on the master system, and restore them on the target. If home directories are shared between the two (perhaps via NFS), you could choose to not include home directory contents in the backups.

I see your point.
I am doing an initial backup restore from restore-domain.pl through a command line script.
I had some problems in that script regarding restore of dns and that's what's keeping me from using this procedure for synchronizing users as well.
I wanted to exclude dns setup from restoring on the backup server since the domain in the backup server was already setup as secondary dns. The option --except-feature dns on restore-domain.pl didn't work. It checked if the domain was already served by dns and stopped with an error
I had to comment named.conf.local through sed on each server to make the restore and then use the previous named.conf.local I had taken backup before the restore. I don't really want to do this kind of actions for synchronizing users as well. If you can fix --except-feature dns I can try it and maybe this is better.
So
1) I would be happy if --except-feature dns continues without checking anything or restoring anything for dns and this might solve my situation.
2) And I leave as a proposal enhancing Cluster Users and Groups to synchronizing also quota if you think it might be useful
3) And a quick question. Is there a way to check from command line from one of your scripts in /usr/share/webmin/cluster-useradmin, the way you check if users are in sync in the web interface, so that I can take actions only if users are not synchronized?
Thanks!

One option that might help in your case is the --only-features flag, which will not enable or restore features that you disable, such as DNS. Let us know if that helps ..

This is what I did
Backing up from one server
/usr/share/webmin/virtual-server/backup-domain.pl --dest /backup/virtualmin/test-dom.gr.tar.gz --domain test-dom.gr --all-features --except-feature dns --except-feature mail --except-feature mysql --except-feature dir

.. done
1 servers backed up successfully, 0 had errors.
Backup completed successfully. Final size was 30.55 kB
I assume that this excludes dns, mysql, postfix and files. Am I correct?
I am trying to use the only-features flag to restore
/usr/share/webmin/virtual-server/restore-domain.pl --source /backup/virtualmin/test-dom.gr.tar.gz --domain test-dom.gr --feature ftp --feature logrotate --feature status --feature unix --feature webalizer --feature webmin --feature web --only-features --no-reuid

.. all features in backup are supported
Starting restore..

.. done
Restoring backup for virtual server test-dom.gr ..
Error: setquota: user test-dom does not exist.
-----
setquota: user test-dom does not exist.
What went wrong? Am I not restoring a feature? I don't know though where to find the short names of all features. I saw some scripts like feature-dir.pl so I used these short names. Can you provide me with a list or a suggestion where to search.

For the backup, you can include all features if you like .. but including only those you want to replicate is also OK.
For the restore error, does the target system have disk quotas enabled? If so, does a Unix user named test-dom exist in the /etc/passwd file?

The target system didn't have a user test-dom because I wanted him to be created by the script.
I added --feature dir and now it creates user as well.
/usr/share/webmin/virtual-server/restore-domain.pl --source /backup/virtualmin/test-dom.gr.tar.gz --domain test-dom.gr --feature dir --feature ftp --feature logrotate --feature status --feature unix --feature webalizer --feature webmin --feature web --only-features --no-reuidI think this command Is good for initial restore
Now I change plan on the domain on the master server, add a user and then take a full backup
Trying to restore with the same command adding --feature ftp --feature mail --feature virtualmin
/usr/share/webmin/virtual-server/restore-domain.pl --source /backup/virtualmin/test-dom.gr.tar.gz --domain test-dom.gr --feature dir --feature ftp --feature logrotate --feature status --feature unix --feature webalizer --feature webmin --feature virtualmin --feature web --feature ftp --feature mail --only-features --no-reuid

Everything is OK
This one worked also to apply changes (as a second restore not as a first)
/usr/share/webmin/virtual-server/restore-domain.pl --source /backup/virtualmin/test-dom-s2.gr.tar.gz --domain test-dom-s2.gr --all-features --except-feature dir --except-feature dns --except-feature mysql --no-reuidExcellent!
I tried dir feature to apply quotas and that worked and guessed there might be a feature virtualmin which also changed the plan, but I would like some directions on where to find more info.
Is there anywhere a full list of supported short feature names and any help on what they do?
Thanks for all replies!

Cool, glad you got that working.
You can find a list of feature codes from the command
virtualmin list-featuresDoes that answer all your questions?
