5. Upgrade Instructions
Follow the instructions from the Parallels Pro Control Panel 10.3.5 for Linux Upgrade Guide.
6. Known Problems and Limitations
- ClamAV (clamd service) will not start after upgrade, if it cannot start before upgrade (because of corrupt antivirus database files).
Solution: before upgrade, deinstall clamav-db RPM package with --nodeps, and remove corrupt /var/clamav/main.cvd, /var/clamav/daily.cvd files.
Another solution: after upgrade, run the following commands as the root user on Parallels Pro Control Panel server:
freshclam
service clamd restart
- CGI is not working for subdomains after the site was
imported despite the CGI that was enabled for subdomains before export.
Solution: KB 6190.
- In some circumstances Apache could crash nearly at 4AM. Solution: KB 6185.
- ProFTPD service may not start after the installation from Parallels Virtuozzo Containers templates. Solution: KB 6229.
- During operations on virtual filesystem Invalid cross-device link errors can be produced.
Solution: KB 5565
- Freshclam process starts despite ClamAV disabled. Solution: KB 5566.
- Problem with shared libraries when importing sites from Parallels Pro 4.x 32 bit to Parallels Pro 10.3.x 64 bit. Solution:
KB 5564
- Problem with resuming a site previously imported from Parallels Pro for Linux 4.x. Solution: KB 5766
- Parallels Pro Control Panel 10.3.5 Beta installed from
Virtuozzo Containers template needs additional actions to be performed
when adding an IP-based site if the container has a host-routed set. For
more information, refer to the section Creating an IP-based Site of
Parallels Pro Control Panel for Linux 10.3.5 Quick Start Tutorial for
Service Provider at Parallels Pro Control Panel documentation page.
- Upgrade may fail when httpd was not stopped before the upgrade.
- Installation of the ensim-postnuke package fails on x86_64 architecture.
- Parallels Pro Control Panel cannot be installed on FC 6/
FC 4/ RHEL 5/ RHEL 4/ CentOS 5.0/ CentOS 4.4 systems enabled with
SELinux.
- Creating sub-folders under the Inbox folder, using the
email client Microsoft Outlook, fails with an error. This is a known
limitation with the email client Microsoft Outlook.
- Parallels Pro Control Panel supports the Python version
that is packaged with the operating system you install on the server.
You can upgrade Python to updates released by the operating system at
any time, however, you must not upgrade Python to a version that is not
supported by the operating system you installed on the server.
- Parallels Pro Control Panel does not support InnoDB
tables with MySQL databases. Importing sites that have InnoDB tables
causes the process to fail with errors.
- Attempts to add or update the zone records created
manually using the Add New Zone option (Zone List page) in Parallels Pro
Control Panel fails returning the user to the DNS configuration page.
Solution: To resolve the issue, log in as the root
user to the Parallels Pro Control Panel server, and restart the BIND
service by running the following commands:
rndc reload
service named restart
- Parallels Pro Control Panel fails to upgrade
SpamAssassin version 3.0.1 (installed by default with RHEL 4/ CentOS
4.4) to the required version 3.0.3.
- The Parallels Pro Control Panel services fail on FC 6 servers, because of dependencies issues of the kernel-xen RPM.
Solution: To resolve the issue, ensure that the virtualization option is not selected while installing Fedora Core 6.
