I have been using the procedure for resizing hard disks for VM images on ESXi hosts documented at https://cwiki.apache.org/confluence/display/VCL/How+to+Increase+the+Size+of+a+Virtual+Machine+Hard+Drive+Under+VMware+ESXi with no problems in the past.
Suddenly, I'm now getting this error in vSphere client when I try to remove the original hard disk of the VM, and add the copy that was made from it and resized: "Cannot remove virtual disk from the virtual machine because it or one of its parent disks is part of a snapshot of the virtual machine." This is after making an imaging reservation for the image, shutting down the vm, making a copy of the current disk and resizing it using: vmkfstools -i original.vmdk copy.vmdk -d thin vmkfstools -X 35G copy.vmdk I can't think of anything that has changed in the setup (VCL 2.3.1 or ESXi) since I last did this successfully. I've tried with several different images on differ ESXi hosts and get the same result. I've tried on both ESXi 5.1 and 5.5 hosts. Has anyone else seen this? -- Mike Waldron Systems Specialist ITS - Research Computing Center University of North Carolina at Chapel Hill
