ESXi 5.0 and 5.1 with VMFS5
On ESXi 5.0 and 5.1 and newly formatted VMFS5, a standard 1MB block size is available. The maximum file size is 2TB - 512Bytes.
Block Size / Maximum File Size 1MB 2TB - 512 Bytes
ESX/ESXi 4.1 and ESXi 5.1 with VMFS3
On ESX/ESXi 4.1 and ESXi 5.1 using a VMFS3 datastore, the maximum file size corresponds to the block size of the VMFS datastore:
Block Size / Maximum File Size 1MB 256GB
Block Size / Maximum File Size 2MB 512GB
Block Size / Maximum File Size 4MB 1TB
Block Size / Maximum File Size 8MB 2TB - 512 Bytes
ESX/ESXi 4.0 with VMFS3
On ESX/ESXi 4.0, the maximum file size corresponds to the block size of the VMFS3 datastore:
Block Size / Maximum File Size 1MB 256GB - 512Bytes
Block Size / Maximum File Size 2MB 512GB - 512Bytes
Block Size / Maximum File Size 4MB 1TB - 512Bytes
Block Size / Maximum File Size 8MB 2TB - 512 Bytes
Step 2. Move Files to Accommodate Space Requirements
This step describes how to resolve this error by changing either the location of the virtual machine configuration files or the workingDir to a
datastore with enough block size.
The is the location where the snapshots are created, By default, the workingDir contains the virtual machine's configuration file.workingDir .vmx
To change the workingDir directory to a datastore with enough block size, see the VMware solution Creating snapshots in a different location than
.default virtual machine directory (1002929)
To move the virtual machine's disks and/or configuration files, use Storage vMotion or cold migration with relocation of files. For more information,
see the following VMware documentation:
vSphere 5: section of the .Migrating Virtual Machines vCenter Server and Host Management Guide
vSphere 4.1: section of the .Migrating Virtual Machines vSphere Datacenter Administration Guide
vSphere 4.0: section of the .Migrating Virtual Machines vSphere Basic System Administration Guide
If the virtual machine already has snapshots, some procedures may not work, or they may attempt to create a snapshot. This table lists the
requirements for the various procedures:
Procedure Requirements
Storage vMotion The virtual machine must not have snapshots on ESX/ESXi 4.1 hosts
or earlier. It may have snapshots on ESXi 5.0 or later.
Cold migration with file relocation The virtual machine may have snapshots. The source and destination
hosts must be running ESX/ESXi 3.5 or later.
Change workingDir The virtual machine may have snapshots. When new snapshots are
created, new redologs are placed in the workingDir directory.
A virtual machine on NFS or VMFS has a maximum virtual disk size of 2TB - 512Bytes, the same as the maximum in each of these
tables.
On ESXi 5 hosts using VMFS5 upgraded from VMFS3, upgraded volumes inherit the VMFS3 block size. The default block size
for new volumes is 1MB. The maximum file size, regardless of block size, is 2TB - 512Bytes. For more information, see the Sto
