Troubleshooting Virtual SAN on-disk format upgrade to 3.0 failures

Posted on October 13, 2016 by Ramesh B S

This video demonstrates how to troubleshoot Virtual SAN on-disk format upgrade to 3.0, which may fail in small Virtual SAN clusters or ROBO/stretched clusters.

This video demonstrates how to troubleshoot Virtual SAN on-disk format upgrade to 3.0, which may fail in small Virtual SAN clusters or ROBO/stretched clusters.

Attempting an on-disk upgrade in certain VSAN configurations may result in failure. Configurations that can cause these errors are:
– The stretched VSAN Cluster consists of two ESXi Hosts and the Witness Node also called ROBO configuration
– Each Host in the Stretched Cluster contains a single VSAN Disk Group
– A Virtual SAN cluster consists of three normal nodes, with one disk group per node
– A Virtual SAN cluster is very full, preventing the full data migration disk-group decommission mode

During this upgrade, a single point of failure is exposed. Follow all VMware best practices, and your business practices, regarding the backup of important data and virtual machines.

This exposure to additional failure risk is referred to as “reduced redundancy,” and must be manually specified in the Ruby vSphere Console or RVC to allow the upgrade to proceed.

RVTools 3.7 is here!

RVTools 3.7 is here!

It has been a year since the last version. This weekend Rob de Vey finally released RVTools 3.7.
With over 400.000 downloads so far, this is for sure the most used free health check tool that exists. And there is a good reason for it, it is most definitely also one of the bests tools that can provide valuable insights.
RVTools is a windows .NET 2.0 application which uses the VI SDK to display information about your virtual machines and ESX hosts. RVTools is able to list information about VMs, CPU, Memory, Disks, Partitions, Network, Floppy drives, CD drives, Snapshots, VMware tools, Resource pools, Clusters, ESX hosts, HBAs, Nics, Switches, Ports, Distributed Switches, Distributed Ports, Service consoles, VM Kernels, Datastores, Multipath info and health checks. With RVTools you can disconnect the cd-rom or floppy drives from the virtual machines and RVTools is able to update the VMware Tools installed inside each virtual machine to the latest version.
Make sure to follow RVTools on twitter for any updates.

RVTools 3.6 works with VMware vSphere 6.0

RVTools 3.6 works with VMware vSphere 6.0

This little gem of a piece of freeware is very useful for the home virtualization lab enthusiast. Should you decide to use it, don’t forget to consider donating to Robware’s Rob Deveij.

The VMware API 6 hasn’t changed in a way that’d affect tools like the extremely handy and free RVTools. So it’s highly likely you’ll still be able to make good use of this tool as you prepare your home lab for vSphere 6:

• looking for orphaned VMDK files you no longer use
• cleaning up datastores
• saving off ALL your configuration details, such as networking

Especially helpful if you are considering doing a completely fresh vSphere 6.0 install, with the new vCSA appliance. You can very quickly see everything you have, sort the various views, and export it all to Excel or CSV.

Even after you’ve made the move to vSphere 6.0, there seems to be no issue with continuing to use the tool. This is good! Using the tool is pretty self evident, and I wouldn’t want to take away any of your fun in exploring the various tabs.

As was the case before, you can log in to either the:

• ESXi host
• vCenter server

In my case, I logged RVTools into the vCSA 6.0 appliance, in the very short install/configure video seen below.

Enjoy!
