When you creating a Datastore in your VMware environment there are two file systems that you can select for your Datastore
VMFS-3 (Old file System)
VMFS-5 (New file System)
VMFS 3 is the old file system and here I’m going to show you how to Upgrade your old VMFS3 Datastore to a VMFS 5 Datastore which is known as the new File system in VMware. Datastore is the main Storage component which keeps all the Virtual Machine related files. There can be local and shared Datastores, if you are using features like vMotion in your environment there should be a shared Datastore which can be accessed from all your ESXi Hosts. You can use a feature called “Enhanced vMotion” which you can migrate your Virtual Machines without a Shared Datastore. But this is not an article to explain those concepts.
There are three main methods which you can use to upgrade your old VMFS 3 Datastore to a VMFS 5 Datastore.
- Using vSphere Client
- Using “esxcli” command
- Using vmkfstools
Upgrade using vSphere Client
Upgrade using “esxcli” command line tool
Once command complete the upgrade your Datastore will be upgraded to the VMFS-5 file system.
