SME Server 8
Status: Final Release
SME Server Version 8.0 is the current major version of SME Server, and is based on CentOS 5.8.
See the Release Announcement for 8.0 Final.
A copy of the latest CD image can be downloaded here.
Testing
All users are encouraged to test, see our draft quality assurance testing page for tasks SME8.0 QA
All testing should be based on the released version plus updates from smeupdates-testing.
Considerations before installing
Please report any issues to our bug tracker under the SME Server 8 section only if you have installed all current updates.
This way all problems can be fixed as quickly, early and efficiently as possible by the development team.
Contrib owners/maintainers should check their packages for compatibility on SME Server 8.0 final and update them if necessary.
For comments regarding contrib test results on previous SME8beta releases see SME8.0 Contribs QA
Upgrade paths
Check for rpms installed from outside the standard yum repositories and remove at least all contribs:
/sbin/e-smith/audittools/newrpms
CD
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.
If upgrading with less than SME Server 8.0 Beta 6, reset repositories to SME 8, see below, bug bugzilla:5705. This is fixed for SME Server 8.0 Beta 6
Yum
Even if possible and tested the yum upgrade must be performed only with stable internet connections and, above all, not remotely. Loosing connection may leave your system in an unknown state.
Check for known issues, here SME8.0 QA and at open bugs for SME 8 in bugzilla.
Note especially bugzilla:5316, detach all USB drives, ie your backup
Pointing repositories to SME 8
Update the MirrorList property to point to the sme8 lists...
db yum_repositories print | grep '^sme' | cut -d= -f1 | while read repo
do
db yum_repositories setprop $repo MirrorList \
http://distro.ibiblio.org/pub/linux/distributions/smeserver/mirrorlist/$repo-8
done
Expand your yum.conf...
/etc/e-smith/events/actions/generic_template_expand yum-modify
Performing the upgrade
- Clean out the yum cache so upgrades work: yum --enablerepo '*' clean all
- Perform the upgrade: yum --disablerepo '*' \ $(echo --enablerepo\ sme{os,updates,extras,addons}) \ upgrade
- Remove outdated rpm database and rebuild it (zeros not O's) rm -f /var/lib/rpm/__db.00* rpm --rebuilddb
- Reset yum updates repositories to defaults, (will delete local changes) mv /home/e-smith/db/yum_repositories /home/e-smith/db/yum_repositories.pre8 /etc/e-smith/events/actions/initialize-default-databases
- Perform a post-upgrade and reboot signal-event post-upgrade signal-event reboot
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, use the following command to see if there are any remaining el4 packages installed that may require an upgrade from the smecontribs repository.
rpm -qa | grep el4
Note that some of the contribs packages may be listed as an el4 package but function correctly on SME8. Check the SME8.0_Contribs_QA pages for more information.
Potential issues that may arise
If you are running a 7.0 system you may need to upgrade smeserver-yum.
- Check which version of smeserver-yum you are running: rpm -q smeserver-yum
- If it isn't at least 1.2.0-25.el4.sme install an updated version: rpm -Uvh \ http://mirror.contribs.org/smeserver/releases/obsolete/7.1/smeos/i386/CentOS/RPMS/smeserver-yum-1.2.0-25.el4.sme.noarch.rpm \ http://mirror.contribs.org/smeserver/releases/obsolete/7.1/smeos/i386/CentOS/RPMS/yum-plugin-fastestmirror-0.2.4-3.c4.noarch.rpm
If you receive the following error while trying to upgrade:
--> Finished Dependency Resolution Error: Missing Dependency: yum-metadata-parser is needed by package yum
Solve it by installing the correct version of yum-metadata-parser:
rpm -Uvh --oldpackage \ http://mirror.contribs.org/smeserver/releases/7/smeos/i386/SME/RPMS/yum-metadata-parser-1.0-8.el4.centos.i386.rpm
Upgrading samba
The Samba packages in SME Server 8.0 Beta 6 have reverted to those provided by CentOS to simplify the support needed. This version of samba provides support for Windows 7 domain logins. Due to this change from samba-3.4 to samba3x-3.3 it is necessary to remove samba if samba-3.4.x has been installed. All users of SME Server 8.0 Beta 5 are affected. Users of other versions of SME Server can check their samba version.
rpm -q samba samba3x
Here is the example output showing samba 3.4 packages installed which need removal.
samba-3.4.3-1.1.el5.sme package samba3x is not installed
Here is the example output showing samba3x 3.3 packages installed which need no further steps
package samba is not installed samba3x-3.3.8-0.52.el5_5
If samba-3.4.x then you need to run two commands:
rpm -e --nodeps libtalloc libtdb samba samba-client samba-common samba-winbind
yum install tdb-tools
Now you are ready to upgrade to SME Server 8.0 Beta 6
USB drives
USB drives are detected differently on SME8, see http://wiki.contribs.org/USBDisks#USB_on_SME_8
Additional steps and potential changes
VMWare
VMware-server installations need some tweaking at this stage, see VMware_server_on_SME8.0beta5.
Problems and bugs
If you have any bug issues with upgrading please open a new SME Server 8.x file a bug here
Major Changes
- CentOS 5 has dropped support for i586 and therefore SME Server 8 will not work on i586 hardware. See
bugzilla:2845. i586 hardware means processors before and including Intel Pentium, Pentium MMX; AMD K5, K6, K6-II, K6-III and Via C3. i686 architecture processors are Intel Pentium Pro, Pentium II, Pentium III; AMD Athlon, Athlon XP and later.
