SME Server 9.2RC1 Release Notes

The SME Server development team is pleased to announce the release of SME Server 9.2RC1 which is based on CentOS 6.8 Release Notes

Bug reports and reports of potential bugs should be raised in the bug tracker (and only there, please);

The Koozali SME Server project

The Koozali Foundation Inc. is a nonprofit corporation that governs the open source Koozali SME Server project. Koozali SME Server is a stable, secure and easy to use/manage linux server that provides common server functionalities out of the box. Many open source contributions are available that can extend the default server functionality making Koozali SME Server an even more powerful and flexible business server solution. Thousands of Koozali SME Severs have been deployed as real or virtual servers and in the cloud to serve many small to medium enterprises, and this number is growing day by day. The Koozali SME Server is free to use but it takes a lot of effort and money to develop, make, and maintain. We therefore ask you for your considerations.


Koozali Foundation Inc. together with it's community hosted at are a collaborative effort of volunteers. You too can contribute to the development and continuity of the Koozali SME Server project as described on our volunteering page. Everybody is welcome to join the already 4000+ member community and with any skill set.

About SME Server

SME Server is the leading Linux distribution for small and medium enterprises. SME Server is brought to you by Koozali Foundation, Inc., a non-profit corporation that exists to provide marketing and legal support for SME Server.

SME Server is freely available under the GNU General Public License and is only possible through the efforts of the SME Server community. However, the availability and quality of SME Server is dependent on meeting our expenses, such as hosting costs, server hardware, etc.

As such, we ask for a donation to offset costs and fund further development. a) If you are a school, a church, a non-profit organisation or an individual using SME Server for private purposes, we would appreciate you to contribute within your means toward the costs associated with hosting, maintenance and development. b) If you are a company or an integrator and you are deploying SME Server in the course of your work to generate revenue, we expect you to make a donation commensurate with the level of revenue you generate and the number of servers your have in the field. Please, help the project

The development team would like to thank all of those who have involved themselves with this release.


In-place upgrades are not supported. It is necessary to backup and then restore. /boot partition is always RAID 1.

The spare handling for RAID arrays is not implemented.

USB installs are now supported, see:


Hardware requirements

Installation procedure



Important.png Note:
In-place upgrades to SME 9.2 *are* supported - from 9.# only.

Important.png Note:
You are advised to only upgrade clean machines, e.g. without contribs or other modifications.


This is the most affordable way to get a clean and secure upgrade. During the upgrade process the existing installation is detected and the option to upgrade the existing system is displayed.


Even if possible and tested the yum upgrade must be performed only with stable internet connections and, preferably, not remotely. Loosing connection may leave your system in an unknown state.

Check for known issues, here Dashboard and at open bugs for SME 9 in bugzilla.

Check for contrib packages that may need upgrading

Even though it is recommended that you only upgrade clean machines (e.g. without contribs or other modifications), it may be possible that you have a contrib installed that you forgot about. After the upgrade, check if any contribs may require an upgrade from the smecontribs repository.


Important.png Note:
In-place upgrades from SME 8.# to SME 9.x using yum or CD are not supported due to design constraints imposed by CentOS.

It is necessary to backup the old server & then restore to the new server. Contribs will need to be reinstalled.

The simplest way to do this is via a Console Backup to attached USB disk on the old server. Alternatively use one of the Backup & Restore options available in server manager panel, ie backup to desktop, or backup to workstation (either to attached USB or network share). Other non standard options exist to Backup virtual servers that do not have USB ports etc, & Restore to similar virtual systems, eg using ssh.

Information.png Tip:
The Restore from USB on first boot function (on a newly installed SME 9 server), will only utilise backups that are saved as smeserver.tgz files, which are the Console backup to USB or the server manager backup to Desktop. The server manager backup to Workstation (either to USB or network share) creates a "backupdate.dar" type filename (or multiple split parts) & cannot be used to restore using the Restore on first boot function, it can only be used for restores from server manager.

Information.png Tip:
After a Restore to new hardware, networking may not be functional. This is caused by the restored NIC settings being incorrect for the NIC's in the new hardware. To fix this, login as admin & from the console menu select Configure this server. Step through the screens & choose the new hardware network card (NIC) drivers, & leave other settings unchanged.

Upgrade via Console backup to USB drive

  • Log in as admin & Backup the old server via a Console Backup to attached USB disk. This may take many hours if you have a lot of data on your server, depending on USB port speed, USB drive speed, & types of files being backed up ie whether already compressed or not etc. Typically for 250Gb of data on your server hard drive, 2 to 4 hours.
  • Install the SME 9.x OS from CD on the new hardware (on new server).
  • Select to do a Restore on first boot of the newly installed SME Server 9. Only attach USB containing the backup file, when asked on first reboot. Restore may take a few hours depending on data size etc. Make sure you wait for the Restore complete message.

Upgrade via server manager backup to Desktop or Workstation (USB or network)

  • On the old server in server manager, configure the required backup in the Backup or Restore panel. Schedule the backup to run at a suitable time. This backup can be to a workstation desktop for systems with a smaller amount of data, which creates a smeserver.tgz backup file, or to a locally connected USB drive or to a network share, & creates xx...xx.dar files, split into multiple parts if configured & data size is large. This may take many hours to run depending on data size etc.
  • On the new SME9 server, manually configure the identical backup job in the server manager Backup or Restore panel. The backup job MUST point to the exact same location that the original backup file is saved to.
  • Select the Restore function within server manager & select the full backup you want to restore from. This may take many hours to run depending on data size, network speed etc. Make sure you wait for the Restore complete message.
  • Basic networking configuration of the new and/or restored SME9 server will be required if different from original server.

Upgrade using command line restore via ssh or USB

  • It is possible to use the command line to transfer a backup file via ssh (or USB) to the new server & then to run the restore. Standard & non standard backup concepts & procedures are outlined in the Backup server config Howto, If using any non standard method, then the integrity of your SME server data cannot be guaranteed.
  • To do a standard backup & restore using CLI, on the old server log in as admin & perform the Console Backup to USB drive (to a locally connected USB). Alternatively using suitable commands, a smeserver.tgz backup file could be created & saved to / folder, refer Howto.
  • Install the SME 9.x OS from CD on the new hardware (on new server).
  • Answer No when asked if you want to restore from USB during the first boot.

  • If you created or have the backup file on the old server, transfer the smeserver.tgz backup file via ssh from your old server to your new server. Both servers must be connected & remote access enabled
  • On the old server do:
scp -P zzzz /smeserver.tgz newserverIP:/

(where zzzz = port number)

  • If you saved the backup file to USB, then transfer the smeserver.tgz backup file from USB to your new server
  • Log in as root or a root user on the new server & do:
mount /media/usbdisk
cp /media/usbdisk/Backup-date-folder/smeserver.tgz /

(replace usbdisk with actual mount point name & Backup-date-folder with actual folder date name)

  • After the backup file has been copied to the new server, on the new server do:
cd /
signal-event pre-restore
tar -C / -xzvf smeserver.tgz
/sbin/e-smith/signal-event post-upgrade
/sbin/e-smith/signal-event reboot
  • Before restarting the new server, disconnect old server from network (as you will have clashes due to duplicate IPs)
  • On new server do:
cd /
rm smeserver.tgz
  • Note the backup & restore may take many hours to complete depending on data size etc.
  • After restore, the Configuration of the new server should be identical to the old server.
  • Note with two servers connected during ssh copying operations, basic networking configuration of the new unrestored SME9 server will need to be temporarily different to the old server to avoid clashes

Reinstall Contribs after restore

Add on contrib rpm packages will need to be re-installed on the new SME 9.x server as these are NOT included in the backup. Contrib data & configuration is included in backups & will be restored, but its usefulness will depend on the contrib design being unchanged between older (SME7/el4 or SME8/el5) & SME9/el6 package versions.

Delete & Reconfigure Manual tweaks

Other manual tweaks eg custom templates or scripts, will need to be deleted & recreated in line with SME 9.x template code & base code.

Where extensive modifications have been made to the "old server (eg SME8.1)", it is recommended to carry out a test backup & restore upgrade first, to discover any problems & ascertain suitable fixes & workarounds. Removing contribs & custom templates before upgrading is recommended.


/boot partition is always RAID 1.

The spare handling for RAID arrays is not implemented.
