Hey guys,

I am trying to backup a VM here, we use ESX 4.1.0, and its throwing an error when trying to create a virtual machine snapshot.

"File <unspecified filename> is larger than the maximum size supported by datastore <unspecified datastore"

We use an MD3200i for storage. Thanks!

This is because the size of the virtual disk (vmdk) and the snapshot when added together exceeds 2TB-512bytes which is the maximum size of virtual disk under 4.1

What is the size of the virtual disk?

Options.

1. Reduce the size of the virtual machine disk.

2. relocate the snapshot to another datastore.

Size of disks?

okay, also the VMFS datastores support different files sizes for virtual disks....

• 1MB block size – 256GB maximum file size
• 2MB block size – 512GB maximum file size
• 4MB block size – 1024GB maximum file size
• 8MB block size – 2048GB maximum file size

I would think you have exceeded the block size for your VMDK.

Option 3.

Change the block size of the disk. (needs a re-format!).
