OpenNode Update Error
« on: February 15, 2012, 02:18:05 AM »
Doing "yum update opennode" gives me the following error because I have newer vzkernel's installed.

Code: [Select]
Transaction Check Error:
  package vzkernel-2.6.32-042stab048.1.x86_64 (which is newer than vzkernel-2.6.32-042stab044.17.x86_64) is already installed
  package vzkernel-2.6.32-042stab049.2.x86_64 (which is newer than vzkernel-2.6.32-042stab044.17.x86_64) is already installed
  package vzkernel-2.6.32-042stab051.1.x86_64 (which is newer than vzkernel-2.6.32-042stab044.17.x86_64) is already installed

You have to downgrade your hosts kernels to vzkernel-2.6.32-042stab044.17.x86_64.
Download kernel rpm manually and install with yum downgrade.

The problem occours because you have upgraded your host kernels directly from openvz repo to newer versions that have not been yet officially tested/included in opennode. Recently we decided to go back to strict kernel versioning - eg opennode rpms are tied to specific openvz kernel versions from now on (as they were in OpenNode 1.1 series). There are several  reasons for that - one of them being caused by recent event where stable openvz kernel was not really "stable". So we decided to go back to control kernel versions with opennode rpm and not to allow people to use different kernels at will. We understand that it is a limitation - but imagine also dealing with multitude of problems arising from different kernel versions with the same OpenNode code level.

Actually we were planning to use ksplice service for live kernel patching - which would then solve quickpath for important security fixes without actually changing installed kernel - but sadly ksplice was acquired by Oracle and limited ksplice support to Oracle Linux only. No alternatives have emerged so far.

OK, as long as it is intended.  I will work around it by doing the RPM manually instead of using YUM, no big deal.
