  2. Select the other (not the local) V-Cube+ node and change into the Start Maintenance dialog.
  3. Now, put this other node into maintenance mode by confirming the query in the dialog. Wait until the maintenance mode is reached. Depending on the number of virtual machines and hard disk, this can take some time. Virtual machines will be migrated live, which can take a few minutes depending on the size of the RAM. The progress will be displayed in the list of background activities.
  4. Close the dialog.
  5. In the list of nodes, select again the other node whose software is to be updated by right-clicking it.

New in this Version

New Add-on module - Collax V-Transfer

With this version, the new add-on module “Collax V-Transfer” is available. It gives administrators more flexibility in handling the VMs and increases scalability when the Collax V-Bien, Collax V-Cube and Collax V-Cube + interact. Because Collax Transfer provides functions transferring VMs between the products.

With just a few clicks of the mouse, it is possible to transfer a VM directly between two Collax V servers or the storage type and change other properties prior to transfer. Before the transfer starts, there is a detailed check, whether the VM can be operated on the other side instead. Actions that affect the smooth transmission and errors during the transfer are prevented or intercepted. Together with Collax Central, the operation significantly increased by Collax virtualization solutions. A transfer can be conveniently initiated via the dashboard.

Virtualization: eSAN metadata

When configuring the size of an eSAN (DRBD), the specified value was used for the data including the metadata. This does not correspond to the expected behavior of being able to use the specified size for the memory completely for the data. With this update, the fully configured memory for the data is now available.

System Management: Linux Kernel 4.9.236

This update installs Linux kernel 4.9.236.

Issues Fixed in this Version

Security: Important security relevant System Components

This update will also install/update the following important system components:

CVE-2020-13765 CVE-2020-15863 CVE-2020-12829 CVE-2020-14364 CVE-2020-16092 CVE-2020-8608 CVE-2020-13754 CVE-2019-14563 CVE-2019-14586 CVE-2019-14558 CVE-2019-14587 CVE-2019-14559 CVE-2019-14575 CVE-2019-14559

Virtualization: Console screen resulted in a process being busy

Clicking on the icon in the column of the virtual machines (VM) opens the screen console of the corresponding VM in a separate browser tab. Due to an error in the noVNC software used in this context, the call could lead to a load on one of the processes involved. With the use of noVNC v1.2.0 whitin this update, the behavior is corrected.


Hardware: 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.
