Upgrading NexentaStor to

You may have seen my Fusion upgrade article and now this one is about upgrading NexentaStor to the current GA of 5.0.3.  I am particularly looking forward to the vSphere 6.5 support so I can get the Nexenta vSphere Web Client plug-in working.

I can confirm it is OK to upgrade Fusion first, and NexentaStor second, and I think that is the right way to do it.

I also recommend you follow the exact steps of my upgrade as in the past they worked and slightly different steps did not.

Prep Work

There is no other prep work other than having a backup of what you are running on your Nexenta. Which I do but as I am not in an HA cluster I will be rebooting the array so I need to have the VMs on it powered off.

Here is the release notes and the docs.


  • Log in on the console via SSH.
  • Execute software version to see what your current version is.

  • We can see that 5.0.2 is my current.
  • I also have a cluster error or two, but I don’t have a cluster and I am told by Nexenta that it is not an issue.
  • Now use the software upgrade -n to see what is available.

  • We can see there is outstanding updates.
  • So we now use software upgrade to do the upgrade.

  • The download finishes soon.

  • We see the upgrade start.
  • Before you know it you have a prompt to restart.

  • And we do.  We see at boot in the loader the 5.0.3 choice so things look good.

I go off and do some work and forget what is going on.  I look back and I see on the console that it is still 5.0.2 so I do a manual restart. When it restarts and we can see the console looks healthy we use Fusion to see if things worked.

When we log in to Fusion, we can see on the Administration page of the appliance that it is using now.

Or, if we look on the console after we have logged in, we can also see the version.

So I start my VMs and all is good.

However, I did have a problem.  It did not restart on its own.  When I manually restarted the array it came up with some errors on the console (with SMF mentioned), and when I forced a reboot again, there were other errors. It restarted once or twice on its own, and by morning it was done and in perfect shape.  The console looked good and so did Fusion when I logged in.  I got support and engineering invoked and shared logs and they have not determined exactly what happened.  So the upgrade took longer, and there were some odd moments with strange error messages but it ended well. I have only one issue outstanding and that is my statistics are not working – so total IOPS on my NFS share is blank.  Support / Engineering at Nexenta is investigating.

    Looking into the forums but since Nexenta changed the forums I’ve not had much luck there?
