How to Increase rpool in OmiOS VMware Guest Without a Mirror

If you have ever created an OmniOS VM guest and made the root disk rpool too small, there are 2  pretty simple methods to increase the size of the disk. I found this method to be simpler and more straight forward.  The mirror method is described in an earlier post. The following will outline those steps.  Sections in blue are what you would type:

  • Edit the settings in vSphere for the VM

  1. Increase the VM disk to the desired size, this time make it twice as big as you think you might need
  2. Reboot VM.

incdisk

 

  • On the VM do the following:

  1. Format disk using format command
  2. Reboot VM
  3. Resize rpool
  4. Confirm your work

    I noticed that it’s hard to find your site in google, i found it on 24th spot, you should build some quality backlinks to rank it in google and increase traffic. I had the same problem with my website, your should search in google for – k2 seo services – it helped me a lot

  2. My brother recommended I would possibly like this website.
    He was once entirely right. This post actually made my day.
    You cann’t imagine just how so much time I had spent for this info!
    Thank you!
