→ Applies to: SynetoOS 6.x

 

Step 1. Login to SynetoOS GUI

https://<your_ip_address_or_hostname>

 

Step 2. From Virtualization menu, click on Virtual machines

 

Step 3. Select the VM clone you want to promote

 

Step 4. Write down the Volume ID

 

Step 5. Connect to SynetoOS appliance via SSH as admin ("How to connect to SynetoOS 6 CLI")

Step 6. Promote the VM clone (replace <pool_name> and <volume_id> with the correct information)

zfs promote <pool_name>/syn-volumes/<volume_id>

Wait 5 minutes to allow completion of necessary background operations.

 

Step 7. Remove ‘syneto.clone’ parameter from ESXi ("How to remove 'syneto.clone' parameter from a VM in VMware ESXi")

As a result of this workaround, the system will display replicas of the same virtual machines with zero space usage. 

IMPORTANT
It is mandatory not to delete these replicas, as this would also delete the production VM.
 


If this happens, open a ticket by contacting Syneto Support.

 

Step 8. Protect the VM ("How to protect a virtual machine in SynetoOS 6")
