The maximum file size, regardless of block size, is 2TB - 512Bytes. The default block size for new volumes is 1MB. On ESXi 5 hosts using VMFS5 upgraded from VMFS3, upgraded volumes inherit the VMFS3 block size. If the file can grow beyond the maximum size, ESX cancels the Create Snapshot operation and displays the error message: File is larger than the maximum size supported by datastore The redolog file may not work correctly once it reaches the maximum size of the datastore. Beginning with version 4.0, ESX/ESXi compares the maximum size of a snapshot redolog file to the maximum size of files on the datastore. These errors occur when the snapshot file has exceeded the maximum size to fit in a datastore. Vmx| The destination file system does not support large files. Vmx| Error encountered while saving snapshot. Vmx| SNAPSHOT: SnapshotBranch failed: The destination file system does not support large files (5).

Vmx| SNAPSHOT: BranchDisk: Failed to create child disk ' /vmfs/volumes/uuid/vmname/vmname-000001.vmdk' : The destination file system does not support large files (12) Vmx| DISKLIB-LIB : Failed to create link: The destination file system does not support large files (12) Vmx| DiskLibCreateCustom: if your disk is on VMFS, you may consider increasing the block size.

Vmx| FILE: File_VMFSSupportsFileSize: Requested file size ( 554051831808) larger than maximum supported filesystem file size (274877906944) In the vmware.log file of the virtual machine, you may see an error similar to: Snapshot guest failed: The file is too big for the filesystem. In the hosted log file, you may see the error: In the vSphere Client, you may see the error:įile is larger than the maximum size supported by datastore. Use the steps in this article to resolve the error "VMDK is larger than the maximum size supported by datastore" encountered when creating an ESX/ESXi virtual machine snapshot.
