Common vSAN Troubleshooting Questions Answered

Our monthly webcasts always generate excellent questions from the audience. And when Francis Daly (one of our Staff Technical Training Specialists who trains VMware’s technical staff on all things storage) delivered Virtual SAN Troubleshooting a few weeks ago the questions were outstanding.

We pulled a few of the questions below, and you can read the entire list and listen to the recording on your schedule.

Q: I have a test vSAN environment with 3 ESXi hosts. I set a policy to tolerate 1 failure. I pulled the network cables on one of the ESXi hosts. My VM was still not available after 30 minutes. Shouldn’t it still be available?

A: Yes, If HA is enabled. Please ensure HA is enabled so the VM can start elsewhere in the cluster.

Q: Is there any way to stop a resync operation, or halt it? During VM replication to VSAN, upon powering up VM on vSAN, storage policy takes effect and a resync operation starts.

A: There is no “recommended” way to stop resync this is an expected process. Interrupting it is unsupported at this time.

Q: Are there any recommendations or best practice to follow when you are migrating VMs from non-Cluster vSAN to the vSAN cluster?

A: If both clusters are part of the same vCenter this is a straight forward migration back and forth. Best practice is to test your environment first with non-critical and or test VMs first.

Q: What is most common issue on upgrades?

A: Depending on versions there can be a few different things. Ensure you have run all pre-checks. people performing upgrades before checks can be a big issue. Also ensuring you have enough cluster resources is huge as you need to ensure you can satisfy policies during upgrade.

Q: If I have both vSAN and HA enabled and I pull the NICS on an ESXi host, how long should the failover take?

A: HA is quite fast. It takes as long as is needed to register the VM on the new host and power it on. HA typically takes a matter of seconds to get the VM powered on, then however long the VM takes to boot. It is sometimes slower but HA is a quick process.

Q: What is the free space recommendable in vSAN?

A: 30% per disk group is what we would like so we can rebalance easily if that is required.

Q: Does it make sense, to install more than 1 vSCSI controller in a VM and attach multiple disks to different vSCSI controllers? Will this give me more IOPs?

A: To improve IOPS we usually recommend looking at more disk groups so you can take advantage of a larger amount of cache.

Q: What are the logs we need to collect when there is a problem?

A: Mostly clomd, vobd.log and command outputs help a lot. More details in this KB article.




What’s Coming in 2017? Here’s What the VMware Magic 8 Ball Says



As 2016 wraps up, predictions are flying on what’s ahead for the coming year. What can we expect to see in security? How will networking look 12 months from now? What changes are on the horizon for the cloud?

To help answer some of these questions, we asked VMware’s all-knowing magic 8 ball (i.e., we took a look through all the recent Radius articles and collected the ones that contained 2017 forecasts). Here are some of the top predictions we discovered:

Answering Questions about What’s New in vSphere 6.5

Last month’s free webcast on vSphere 6.5 Training: What’s New gave viewers a high level look at the new features in vSphere 6.5 and why they are important in today’s data centers. It also provided an overview of our new vSphere 6.5 instructor led classes designed to help you and your organization realize all of the benefits of updating your existing vSphere infrastructure to vSphere 6.5.

Below are some of the questions that were covered during the hour-long webcast. A recording and complete list of questions are also available.


Can we upgrade directly to v6.5 from v5.1?

  • No. To upgrade from v5.1 you would need to upgrade to v5.5 first, then upgrade to v6.5.

What is the upgrade path from v5.5 including SRM?

  • Check out this KB article for information about the order in which to upgrade components. There are links to the upgrade documentation for each product.

Will backups be incremental, or will it end up having to back up each full VM every time?

  • The backup APIs remain the same for this version, with the addition that encrypted VMs will be also supported, so incremental backups will still be possible.

Can the VCSA migration support migrating an embedded setup to an external setup?

  • You upgrade to embedded, and then repoint as external.

Will VCSA 6.5 be able to operate in Link mode with older version of vCenter?

  • vCenter servers connected to the same PSC will still work in Enhanced Linked mode.

Can you schedule a backup?

  • No, the vCenter backups cannot be scheduled, it is a manual task.

Will it allow you to migrate from a Windows vCenter 5.5 with an external database to v6.5 VCSA with integrated DB?

  • Yes, the migration tool does just that.

AD authentication is key for us since we have SSO. Does the VCSA supports SSO or this is only a Windows feature?

  • Full support for SSO in the appliance.

Is the entire UI based on HTML5?

  • There are several clients – one of which is H5.

Is there a size limit on Windows server drives or the size of the vMDK?

  • The max vMDK size is 62TB.

The Promise of Software‐Defined Storage (SDS)

Hyper Converged Infrastructure for DummiesTogether with Intel, VMware has released a new ebook covering virtualized storage, Hyper-Converged Infrastructure (HCI), and vSAN.

Hyper‐Converged Infrastructure for Dummies by Michael Haag shows you the ways HCI evolves how compute, storage, and management are delivered and provisioned to help you cut operational and capital costs, increase IT and business agility, and improve application performance.

Chapters explore common use cases, abstraction paths to software defined storage (SDS), getting started, and 10 reasons you’re going to love HCI. As Haag puts it:

Basically, SDS puts the application and its requirements at the top of the IT hierarchy. Now storage can respond to dynamic changes in application requirements.

SDS uses policies to create a just‐in‐time model for storage service delivery. Storage assets and capabilities aren’t configured and assigned to specific applications until they’re needed. Should the policy change, the storage environment responds with the requested new service level.

What matters are the needs of your business. In an age of digital everything and cloud‐savvy end users, you need to quickly deploy IT applications that dynamically adjust storage services so you deliver consistently great performance. SDS helps you get there today.

SDS creates a compelling opportunity for your IT team to fundamentally reenvision how data is stored and managed. Through the introduction of new technologies and associated operational models, you can get ahead of rising storage costs and deliver better and more tailored storage services.

SDS allows you to precisely and automatically match storage supply to application demand.
