Suspend VM: There is no more space for virtual disk

[AlexandrBelokon]

Hello!

I have a cluster of 4 vmware Esxi servers version 7.0.3, + dorado 5000 storage. A 32Tb datastore has been added to the cluster.
The problem is that when copying data over 1TB inside the VM, vCenter suspends the VM:
Message on [name vm] on [name node esxi] in [name cluster]: There is no more space for virtual disk [name disk].vmdk
The volume of the dedicated vmdk disk is 20% occupied. The datastore has 25Tb free. Tell me where could be the error?

Hi,

Is there still disk space on "disk array"? because on the VMWare side when you look at the space available on your Datastore, it may not correspond to the space actually available on the "disk array".

Deduplication and over-provisioning can cause crashes
