By default, Storage vMotion 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. there is no other workaround other than formatting : ( There is a drop-dead maximum on your Volume size that you can create in your RAID util and have ESXi recognize the Volume correctly for a LUN. 5. The max size is 2TB minus 512 bytes, Maximum file size of vmdk is 2TB-512B which is 2,199,023,254,528 B" I don't know why VMware allows us to create vmdk file with size 2TB-512B = 2,199,023,254,528 B and at the same time VMware File <unspecified filename> is larger than the maximum size supported by datastore <unspecified datastore> The Veeam Backup & Replication job fails with the following error: VMFS5. Source and destination datastores are both Netapp Ontap NFS v3 datastore vCenter shows both datastore vmdk max size is 15. The workingDir is Issue/Introduction An administrator attempts to storage vMotion a VM or a VMDK residing on a vSAN datastore to another vSAN datastore or an external storage and vice-versa, encounters an error: File The maximum file size is not limited to 2 TB in the NFS server configuration. With VMFS6, no overhead calculations are required for virtual disks (VMDKs) regardless of the size. I don't get this as I have the block size as 1MB and it should high chance that you will need to format the datastore to change the blocksize for the larger VMDK to be created. Source and destination Problem description The snapshot creation fails for virtual machines with the VMDK size larger than 2 TB. To resolve this issue, either change the location of the virtual machine configuration files or change the workingDir to a datastore with enough space for the snapshot file (s). 81TB Anyone run into this before? I am not sure how the vmdk was The maximum virtual disk size would report as 2TB on the vCenter instead of 62TB which is the maximum supported size for NFSv3. In cases where the snapshot file becomes large, the maximum size of an exported agent volume set Discover our VMware Snapshots "file is larger than the maximum size supported for the datastore" fail resolution. The issue is observed on the I’m going to assume this is a VMFS-3 datastore, as VMFS-5 does not have this issue even with a block size of 1MB. For further IT support, get in touch today Cause This error occurs if VMX file is located in a datastore whose block size does not support the size of the VMDK file for that virtual machine. So I have hit a roadblock on my Veeam backup. Performing the same task of creating or expanding a vmdk disk located on a NFS datastores to a size of more The problem I have is that it keeps complaining that the . With VMFS5, you can create a 64TB File [SourceDatastore] File. ” NOTE: Though VMware’s VMFS5 and VMFS3 support files larger than 2TB, the current maximum VMDK file size is 2048GB minus 512 Bytes. 5 and later, VMFS5 supports a maximum files size of 62TB As per the VMware KB: Support for virtual machine To resolve this issue, either change the location of the virtual machine configuration files or change the workingDir to a datastore with enough space for the snapshot file (s). The maximum exportable size is equal to the VMDK size and snapshot file combined. NOTICE: Strangely i can create a snapshot of another virtual machine Issue/Introduction Symptoms: Cannot perform Storage vMotion Storage vMotion fails Cloning a virtual machine or a virtual disk fails In the Migrate Virtual Machine wizard, you see these The snapshot file size is referred to as “overhead. VMFS5 is a new version of vSphere Virtual Machine File System that offers improved scalability and performance, and provides internationalization support. vmdk is larger than the maximum size supported by datastore 'DestinationDatastore' It seems, according to this thread, that 2Tb is shown as the maximum virtual VMware - Creating a snapshot for a virtual machine fails with the error: File is larger than maximum file size supported After looking at this, it's not entirely clear what I have to do to fix this.
