Learn how to upgrade a VMFS data store from VMFS3 to VMFS5. Rick Crisci explains the implications of upgrading a data store vs. creating a new one.
- [Instructor] In this video I'll explain how to upgrade VMFS3 datastores to VMFS5. And the VMFS3 upgrade process is fairly straightforward. You can perform these upgrades using the vSphere Web Client, the vSphere Client, or the command line, whichever tool you prefer. Now, as you upgrade the VMFS3 datastore to VMFS5, your virtual machines can continue to run on that datastore during the upgrade process. It won't affect powered on virtual machines.
However, any hosts that are currently using the VMFS datastore must support VMFS5. Now, as you perform this upgrade, certain aspects of the VMFS3 datastore are not going to change. For example, VMFS3 has multiple block sizes that you can choose from when you create a datastore, however, VMFS5 only has a block size of one megabyte. Now, as you upgrade your datastore from VMFS3 to VMFS5, the block size that you have in place will remain.
It will also keep the same sub-block size. So, what does this mean? Well, when you store really small objects on a VMFS datastore, it can store multiple objects per block. So, for example, if you have an object that's only eight kilobytes in size, why store it on a one meg block? If we can just consume part of that one meg block, that would be ideal. So, VMFS5 enhances VMFS3 because it supports a smaller sub-block size.
For this reason, you should really consider just creating a new datastore with VMFS5, and using stored vMotion to migrate your virtual machines from the VMFS3 datastore to the VMFS5 datastore. This is the best practice, and in most cases it's the ideal way to go. However, if you don't have the space to make that happen and you have to do an in-place upgrade of a VMFS datastore, that's supported as well.
