You can connect it to ESXi hosts and transfer files from […]

Thank you! My use case is a home lab off of my laptop. I kept my default windows installation intact but wanted to bring up a VMW 8x environment on an external usb 2TB drive. I did need to have a second usb [thumb] drive that I ended up using for the OS as I got the “read only” message trying to partition the single usb drive. All good. Thanks for posting this!

I don’t think it can be done since you are trying to format a free partition on the same volume that ESXi is running from. That’s likely why the device is locked to read-only.

Perhaps use a local disk as your datastore or plug in another USB and format that for dedicated storage while keeping ESX on it’s own storage.

But when I try in create the partition I get this error:

[root@localhost:~] partedUtil setptbl /dev/disks/mpx.vmhba32:C0:T0:L0 gpt “10 7086080 15470594 AA31E02A400F11DB9

Error: Read-only file system during write on /dev/disks/mpx.vmhba32:C0:T0:L0

It seem to be read-only 🙁

Any solution?
