General information and recommendations about CloudBoot OS and Integrated Storage upgrades
Starting with OnApp 5.0 LTS, we have made some changes to updates for CloudBoot OS and Integrated Storage. CloudBoot OS upgrades that include security patches, kernel upgrades and updated drivers will be released on a regular basis. If a security patch was released by CentOS, it will be included in the next released RPM. These releases may not include updates for Integrated Storage, a component of CloudBoot OS, as this platform is stable and does not require changes with every release.
For the best experience, stability, and security OnApp recommends that the CloudBoot compute resources should be upgraded by reboot at a convenient time if a new CloudBoot RPM is released. This is required to completely apply the security patches, kernel upgrades and updated drivers.
Integrated Storage as a platform does not strictly require a CloudBoot compute resource to be rebooted after upgrade. However, in case of critical updates and fixes, it may be required to reboot a CloudBoot compute resource for them to take full effect.
This upgrade method requires to reboot CloudBoot compute resources with all virtual servers powered off to apply security patches, kernel upgrades and updated drivers to CloudBoot OS. Simple Reboot is the fastest and the safest way to upgrade but does result in some downtime for virtual servers. Integrated Storage virtual disks do not become degraded. This upgrade method also upgrades the Integrated Storage platform as a component of CloudBoot OS.
Migrate and Reboot
This upgrade method requires to reboot CloudBoot compute resources to apply security patches, kernel upgrades and updated drivers to CloudBoot OS and Integrated Storage. Your virtual servers will remain online, you only need to migrate them from CloudBoot compute resources that will be rebooted. Keep in mind that it is required to repair any degraded virtual disks before proceeding with reboot.
