My brain is screaming obscenities because I have spend the last 2 hours trying to delete a datastore from ESXi4. It’s a small 16G one (the one I was using to try and copy to a USB stick) which resides on a 500G internal SATA drive. I have been trying from the vSphere client and from the command line with more and more severe methods culminating in “Reset System Configuration” from the console. Even that didn’t work which only leaves me the option of re-burning my ESXi on USB stick.

The error is as follows:

Error from Delete Datastore

Don’t bother to ask me to try something. I’ve tried it all.
