Time Synchronization in VMware Environments
It is important that the Anvil and DSX nodes are time synchronized. DataCore vFilO uses Network Time Protocol (chrony implementation) and the Anvil acts as a time server for all DSX nodes. In VMware environments, vSphere can sometimes adjust the clocks on the virtual machines and this can cause the DataCore vFilO nodes to lose time synchronization. For this reason, it is necessary to follow the guidance in the following VMware Knowledge Base article: Disabling Time Synchronization.
Before installing Anvil and DSX, configure the environment as follows:
- Launch the vCenter web client.
- Select the virtual machine in the vSphere Web Client inventory and power it off.
- Right-click the virtual machine and choose Edit Settings.
- Click the VM Options tab.
- Expand the Advanced option.
- Under Configuration Parameters, click Edit Configuration.
- Click Add Row and add the following information:
| Name | Value |
|---|---|
|
tools.syncTime When adding tools.syncTime via the Configuration Parameters in vSphere 5.x, it is not displayed again after the entry has been accepted and closed. When you view the vm_name.vmx file, you see the parameter inserted as tools.syncTime = "FALSE". Please refer to Disabling Time Synchronization in the VMware Knowledge Base for more details. |
