On VMTN someone hit a situation where the sps-runtime.log.stderr log file grew extremely large on their vCenter Server Appliance (7.0 in this case). I have seen this before, and sizes over 10GB are not uncommon. The sps-runtime.log.stderr file belongs to the service that provides the Policy-Based Storage capabilities. … [Read more...]

iSCSI IQN may have changed after working after upgrade to 7.0 U2

Last week I noticed some folks reporting that they had an issue with upgrades to 7.0 U2 from 7.0 U1. The issue they experienced was not being able to access their iSCSI Datastores any longer. I did some digging internally and found out there was a change in how we store the iSCSI IQN when the IQN is randomly created. … [Read more...]

How do I change the name of a vSwitch with vSphere 7.0 U2 and higher?

Some of you may have noticed it already, and some may not, but a lot of the configuration details that were traditionally stored in “esx.conf” have now moved elsewhere. The question is where did it go? Well it went into “configstore” and with “configstore” now also comes a … [Read more...]

Last week there was a question on VMTN around maintenance mode, this customer wanted to find out which vSAN Maintenance Mode option was used while the host was placed in maintenance mode.

Issue adding tags to the vCLS VMs with vCenter Server 7.0 U2b

Today I was talking to one of our field folks and he asked if there was an issue with Tags in combination with vCLS VMs in 7.0 U2b specifically.

Can I make a host in a cluster the vSphere HA primary / master host?

There was an interesting question on the VMware VMTN Community this week, although I wrote about this in 2016 I figured I would do a short write-up again as the procedure changed since 7.0u1.

Can 2-node or Stretched be used as client or server cluster with vSAN HCI Mesh?

I had this question today, probably sparked by my post earlier where a showed a single-node cluster being able to leverage HCI Mesh to mount a remote vSAN Datastore. The question was if this also works with 2-node vSAN or with a vSAN Stretched Cluster. Unfortunately, the answer is no, a 2-node cluster or a vSAN … [Read more...]

Using HCI Mesh with a stand-alone vSphere host?

Last week at the French VMUG we received a great question. The question was whether you can use HCI Mesh (datastore sharing) with a stand-alone vSphere Host. The answer is simple, no you cannot. VMware does not support enabling vSAN, and HCI Mesh, on a single stand-alone host. However, if you still want to mount a vSAN … [Read more...]
