Password for relay email server

A server must be selected to send the system emails correctly. If the relay server requires authentication, the corresponding password for the user ID must be entered here. Due to an error, passwords with paragraph characters contained in them did not work. This has been fixed with this update. In addition, a subsequent error when sending the test email was corrected.

Backup functionality

Collax V-Bien temporarily uses snapshots for the backup function. If the operating system of the virtual machine to be backed up was in the initiated sleep mode (pmsuspend), the backup could not be started and was terminated with an error. In the current release an attempt is now being made to wake up the VM in order to enable a successful backup. In addition, under rare circumstances, the scheduled backup of virtual machines does not start automatically. The is beeing fixed within this update.

Changed partition scheme for new installation since version 6.9.0 / Important

when replacing a node

If one of the nodes is defective, it can simply be exchanged via the “Add New Node” dialog. Due to a changed partition schemes take a few things into account. - Both nodes should have nearly identical hardware equipment - Both nodes must have the same version - An additional 10 GB of free space must be available on the storage volume “default” if the version of the existing node at installation was older than 6.9.0. Under “Virtual Disks” click on “Storage Volumes”, then right click on the storage volume “default” and check the free space specified under Size.
