VMware: Creating a snapshot for a virtual machine fails with the error: File is larger than maximum file size supported (1012384)
When Creating a snapshot for a virtual machine fails
Or you receive the error:
File is larger than the maximum size supported by datastore
Note: This error does not occur on ESX 3.5 or earlier.
ESX 4.0 is able to detect when a snapshot file at maximum size cannot fit into a datastore. Instead of allowing the file to be created, which may not work correctly if it grows to big, ESX cancels the operation and displays the above error.
To confirm if the snapshot files may be too big, compare the size of the virtual machine’s base disks against the block size of the datastore which contains the virtual machine’s working directory.
Note: If you are using Raw Device Map, you should compare the size of the RDMs instead of the base disks.
