It’s been a while since I’ve gotten any fresh content on this blog, hopefully I’ll get some content ideas to keep a regular cadence of updates going.

While I was updating the cabling on the garage lab, I realized it had been a while since I had done anything on my CE lab from a version perspective, in fact the last update I had done was March of 2019.  So I figured now was as good a time as any to go ahead and upgrade the CE cluster.

Much like the luck I usually have, I went to upgrade CE thru Prism, and the upgrade seemed to fail with a USB that was corrupted – seems like my USB luck continues on having really crappy USB drives.  So, I went over to Best Buy, bought a few $9.99 64GB PNY USB Drives, came home and started the process to get the image file over to USB, since the CE .iso installer still hasn’t made it’s return.

All was going well, until the hosts booted up.  Now my hosts are a bit long in the tooth, but they are still decent enough with 24 cores and 48gb ram.  This PNY USB drive was HORRIBLY slow, so much so that I couldn’t stand it.  Never again will I buy PNY drives.

So, I thought about what other options do I have.  The drive configuration on these CE nodes was as follows:

  • 1x 256GB Samsung EVO SSD
  • 1x 500GB Samsung EVO SSD
  • 1x 1TB Samsung EVO SSD
  • 1x 1TB Western Digital HDD

So, I figured, why not try to use the 256GB SSD as the boot drive, instead of a USB drive. My Supermicro hosts are old enough that a Satadom might be hard to come by for it, and I honestly had more than enough space on each node, that the 256GB drive wouldn’t hurt too bad.

So, I pulled the drives out of the drive caddy’s, pulled out my trusty Inatek USB Drive Caddy, and proceeded to drop the CE .img file onto the 256GB SSD, using the gdd commands I prefer over the dd command.

Imaging done, and once I correctly set the BIOS on the Supermicro hosts to use the 256GB drive in Port 0, I booted  up each of the hosts and much to my happiness, I was able to get the install to go thru, CVM deployed and cluster created.  And the speed of install was as you’d expect much better!

So in hindsight, with my dislike for USB boot, I wish I had thought of using the internal drive with the .img file.  I did this when the CE .iso installed allowed you to select a boot drive, but for some reason always tried to get the usb drive to work.

So, now I’m happy to say I’m not using the USB drives anymore, have a sturdy SSD drive for my CE boot drive without having to give up much space at all.


Nutanix CE Version 5.6 is out, and it’s hot!!!

With the release of Nutanix Community Edition version 5.6, Nutanix has also provided a new installation mechanism as an alternative to the previous dd imaging method, now allowing for a .iso installer.
