How to expand a block storage by methods.ExpandVmfsDatastore?

[jiangbo202]

I want to expand a block storage that is currently in use through "methods.ExpandVmfsDatastore".

Actual testing found that it is necessary to specify the "EndSection" after expansion
But I couldn't find how to get the "EndSection" after expansion.

I can obtain the last sectors on esxi by using the command "partedUtil getUsableSectors"/vmfs/devices/disks/naa.600a0980383047526e3f4c6c31625xxx".

I tried using "methods. ComputeDiskPartitionInfoForResize" and the result was "Returnval.Spec.Partition[0].EndSector", but what I got was the last sections before the expansion, not the last sections after the expansion.

If I directly use the "EndSection" before expansion, an error message will appear: "ServerFaultCode: Cannot change the host configuration."

I generated code by enabling developer mode on the vmware page, and the EndSection was set directly in the result. I don't know where to obtain it, as shown in the figure
