Hi, thanks for bringing this up. Can you paste the command and complete output, please? Also the version of the knife-vsphere gem you're using, please and thank you.

@jjasghar I am seeing this same issue. Here are some details:

knife-vsphere: 1.2.21 vsphere: 5.5.0

command I am running is:

knife vsphere vm disk extend test-vm 1000000 --folder myfolder --vsdc mydatacenter -p mypassword --vshost myvhost -u myuser -VV

the vm is in a powered off state when running this command.

let me know if you need any more information

What size is the disk already? It may not be well documented but the second command line parameter (1 million in your example) sets the new size of the disk in kB, and you can't shrink a disk. So my guess is you're trying to add a gig of space, when what it's trying to do is shrink it to a gig and throwing an error.

@swalberg that was exactly it! this is working as expected. thank you!

Note for future self or anyone wanting to contribute:

• It's not obvious that we're setting a new size rather than extending
  • Improve documentation
  • Change the behaviour to read the current size and add the param, but consider backwards compatibility
  • Or read the current size and error out if we know it's shrinking
  • Or DWIM and add it to the current size if it's less than the current size (need to think this one through)
  • Support friendlier params like 10g instead of needing 10 zeroes.
