So don't put it on a USB. Boot a liveCD environ and use the IMG to image to your satadom. Than you can boot off that. Gut says you won't even have the dracut/initrd stuff you can find in the forum.

Hi,
the 'dracut stuff' @jrack mentions is (my guess) https://next.nutanix.com/discussion-forum-14/how-to-deploying-nutanix-ce-to-a-local-disk-no-usb-13836/index1.html
If a boot off the image works, that is of course the preferred choice.

Yup tons of posts on that concept. After nuking enough drivers that the supplier was rejecting my rmas I switched to a spindle and have never looked back.

Hi @jrack 

I tried to plugin the SATADOM on my SM E200-8D but the SM SATADOMs are too big if you have the 2.5” slot occupied.
Each of my E200s has 1x NVMe (512GB) and 1x SSD (2TB) connected.

  1. Can I install Nutanix on the NVMe?
  2. If yes how, because I failed booting from the IMG file via KVM connection? (ISOs for other products e.g. XenServer or Windows Server works just fine)
  3. If I can install Nutanix on NVMe will it occupy the entire space or will it behave like a XenServer installation, e.g. partition the disk and only use what it needs to leave the rest for storage?

Kind regards

Hi all,

I just prepped a USB stick with Ubuntu and booted the server with it. I can access the drives now.
What file system do I have to setup for the IMG file to run?

Kind regards

So dusting off my old account since you rang.  You will just “dd” the IMG file to your desired disk.  The linked post above at https://next.nutanix.com/discussion-forum-14/how-to-deploying-nutanix-ce-to-a-local-disk-no-usb-13836 provides the examples.  Instead of Kali you are using Ubnt which will work the same.

The disk img file already has a file system so no need to prep the target.  You are not “installing” CE and more just putting it on a block device as a finished product.

For your previous questions

  1. Maybe, the ramdisk provided used to not have many modules which is why you needed to use dracut.  It doesn’t hurt to try.
  2. So the ISO is a read only file system and pulling it over the network at moderate latency will work.  The IMG is expecting a low latency as it brings the kernel up and a writeable block device which won’t work well over the BMC redirected device.  The kernel is launched readonly to reduce stress on the USB devices, but still have tons of scratch data etc needed for CE to run.
  3. CE historically didn’t support partition targeting so while the IMG will prep an 8GB filesystem you could always expand it, but that extra capacity was not presented to hades for use in NDFS.  If you have those disks behind a hardware RAID card you could carve them up for CE, fast and capacity but you will bottleneck your IO.

Been out of the game for a couple years though so hopefully some things have changed though so not sure if there is a nutant moderator? @aluciani
